In the 1-day Workshop you will build the VM to run a simplified version of a 2D Map Viewer webapplication to explore.
In the 10-day Course you will build the full GeoStack VM to run 3 webapplications: a Dataset Dashboard, a 2D Map Viewer with the OpenLayers geospatial web application framework and a 3D Map Viewer with the Cesium framework.
The datasets used in the course are GPS track logs that are publicly available as Open Content. Two kinds of file formats are used: CSV files with GPS track logs from GPS trackers on the legs of ringed common cranes (Grus grus) from the animal tracking website Movebank.org and GPX files with track logs from a GPS navigation device from travelling routes in The Netherlands donated by a GitHub user as Open Content.
So, now Go, Enjoy and… Learn things!
The repositories of the The GeoStack Project and the project’s YouTube Channel are online as of midday, October 14, 2020!
Tip: check out the 76 introduction, overview and tutorial videos by using the playlists! Quick study in 90 minutes!
Read this project’s home page first!
Follow the advice in the section ‘Skill Levels’ below to check and get the required skill levels for this course.
Follow the steps in the section ‘Getting Started’ below to get the course on your pc or laptop.
Do the 1-day GeoStack Workshop to explore the world of Open Source Geospatial Programming by building the Workshop Virtual Machine using the installation scripts and then by working through the programming assignments to build the simplified 2D Map Viewer webapplication.
Explore the overview videos and tutorial clips on the YouTube channel for the different parts of the full course.
Do the full 10-day GeoStack Course by first building the Course VM the easy way with installation scripts to explore and then building the Course VM the manual way and get the 3 webapplications up and running.
Finally experiment with loading your own datasets and extra digital topographical maps from OpenStreetMap and of course by modifying and extending the webapplications to learn how to build your own dataset visualizations.
The learning goals of this course are to create and run a free and light-weight Open Source Geospatial Software Stack, the GeoStack for short, in a Virtual Machine (VM) with Ubuntu Linux on a stand-alone pc or laptop and to program webapplications to visualize geospatial datasets on locally hosted topographical digital maps from OpenStreetMap and OpenSeaMap.
So this course is about downloading some manuals, software and data sets from the internet, adjust it so it can run on the pc in ‘airplaine mode’ without an internet connection and then learn how to install and configure the GeoStack and program Geospatial Web Applications by using 100% Open Source Software, Open Standards and Open Content!
There are 3 learning goals:
End goal: Programming Webapplications in TypeScript
Intermediate goal: Programming Middleware in Python
a Dataset Dashboard to visualize datasets of GPS track logs that are stored as JSON documents in MongoDB;
a 2D Map Viewer with OpenLayers to visualize the datasets on 2D digital topographical maps from OpenStreetMap (OSM);
a 3D Map Viewer with Cesium to visualize the datasets on 3D maps with Digital Elevation Models (DEM height files).
The intermediate goal is to learn how to build three web services with an API for the web applications to use.
Two web services are required to get access to the 2D and 3D digital topographical maps through the API’s of their respective map tile servers as the geospatial web map servers (WMS) to serve tiled web maps to the web browser.
The third web service is provided by programming a micro web service application with the Python Flask framework to get access to the datasets in the MongoDB datastore.
It is in this Python ‘back end’ web application where the magic happens to program the ‘payload’ or ‘business logic’ for data selection and processing that needs to match the functionality in the TypeScript ‘front end’ web application to visualize the required geospatial data.
Isolating the data processing in a (Flask) web application behind a web service API from that Flask web application uncouples the data processing from the visualization in the front end web applications, making it easy to replace or update either application seperately.
The starting goal is to learn about the approximately 50 software components required in the Client / Server software architecture you will need to download, install, configure, program and run to be able to use the end-user web applications in your web browser.
You will learn about virtualisation to run the course software and data on Ubuntu Linux in a Virtual Machine (VM) completely isolated from your host operating system. In the full course you will also learn how to isolate software components in the VM by using Docker and its Containers and Volumes.
So yes, the GeoStack Installation and Web Application Programming is done on Linux as the guest operating system in the VM. A great opportunity for Linux newbies to explore Ubuntu Linux step-by-step from the Gnome Desktop and the Linux Command Line.
Learn along the way about the architecture and how virtualization helps to update components independently and in sharing your VMs, containers and volumes with other data scientists and software developers.
In order to achieve these learning goals the activities are of course in the reverse order of the learning goals:
Building an Ubuntu Linux Virtual Machine: first you will learn to download all the required datasets and software packages to be stored and installed on your pc or laptop in a Virtual Machine running Ubuntu Linux in VirtualBox.
Data Storage: then you will learn to store the digital topographical maps in the relational spatial database PostgreSQL + spatial PostGIS extension and convert the GPS track log datasets from CSV and GPX files to the JSON dataformat to store the data as JSON documents in the MongoDB datastore.
Programming: finally you will learn how to program in Python and TypeScript in the Atom programming editor and run the web services and web applications locally in your web browser, without the further need for an internet connection (running in ‘airplane mode’).
Depending on your level of expertise you may need to double or triple these time estimates or you might need even more time because there is also a lot of documentation to read, so your mileage may vary!
Don’t worry if it takes you a little longer because you will get there with the user friendly installation and programming manuals with lot’s of screenshots and the Python source code files in Jupyter Notebooks and example scripts in Python and TypeScript with lot’s of inline comments!
If you are on the other hand a real beginner in programming, you might want to invest some extra well spent study time first as a newbie to get to the required skill levels to follow this course as per the advice below in the section ‘Skill levels’!
Assume 1 - 3 days for the workshop x 8 hours = 8 - 24 hours
Assume 10 - 30 days for the course x 8 hours = 80 - 240 hours
Assume 5 - 20 days to build extra skill levels = 40 - 160 hours
Study time range = 128 - 424 hours, so let’s say it’s a range of 3 - 10 weeks depending on your level of expertise and skill set to start with.
TIP: watch the videos first to check your skill level and reduce study time!
1 - Basic skills in Python programming are a must!
Advice: take 5 to 10 days to study the great beginner course ‘Python for Everybody’ by Charles Severance (dr. Chuck).
It’s all Open Content and free to re-use and… also aimed at data scientists with it’s focus on data processing!
Advice: take 5 days to study some beginner tutorials to get a feel for the source code examples used in this course.
3 - Some knowledge of Virtual Box, Ubuntu Linux, MongoDB, Docker, OpenLayers and Cesium comes in handy of course!
Advice 1: take 2 days to properly read up on these topics on their wikipages on Wikipedia and on their project websites!
Advice 2: take 3 days to experiment and get some hands on experience that will serve you well later!
The course manuals en example source code files will guide you to get the software up and running!
To get fast situational awareness there is a 1-day GeoStack Workshop to build the Workshop VM with installation scripts which is documented in both a manual and in a series of presentation files to carefully read to get step-by-step to a working GeoStack and basic end-user webapplication.
The 1-day Workshop focusses on building a Client / Server infrastructure in a VM to get familiar with the server side software architecture of the entire software stack.
To learn all the details after the workshop there is the 10-day GeoStack Course which will take you through all the details to build the Course VM with the full GeoStack and the fully functional end-user webapplications.
About the 1-day GeoStack Workshop
To learn most of the components of the Development Environment, which is described below, to install the required server software for the GeoStack and to program a webapplication this workshop will take you through the whole process to get
familiar with the server and client software architecture for geospatial programming.
The steps will include installing a spatial database, importing topographic maps from OpenStreetMap, install MongoDB as a datastore for JSON documents with geospatial data, prepare and import geospatial datasets in MongoDB, install a Python webserver with a middleware Flask webapplication for data handling, install a NGINX webserver and finally program an end-user webapplication to visualize the dataset on a digital topographical map.
If you are not yet familiar with the components of the Development Environment then just take a day extra to read a little more.
If you’re in a hurry (not recommended!) or just curious then simply run the installation scripts to get to a working GeoStack and webapplication more quickly.
Building the Workshop VM is documented in the cookbook ‘Creating the GeoStack Workshop VM’.
The cookbook ‘Workshop Assignments’ introduces the programming assignments with lots of background information for beginners!
The programming assignments themselves are of course in the Jupyter Notebooks, source code files and configuration files.
About the 10-day GeoStack Course
In the GeoStack Course there are many manuals, cookbooks, installation scripts and programming examples in Python to learn the details of installing, configuring, using and programming all components in the entire GeoStack.
This will take a serious time investment of 10 - 20 or even 30 days of study time to read and experiment with the software and datasets but after that you will have build a GeoStack VM from scratch and you know how geospatial web applications work!
You will also learn to use Docker Containers to run applications and Docker Volumes to host data.
For topographical sea maps you will learn how to add the OpenSeaMap data of nautical objects to your spatial database PostgreSQL/PostGIS and visualise these objects with OpenLayers in a data layer overlay to create a digital nautical map.
At the end of the course you will have 3 working end-user web applications that run in your web browser to visualize geospatial datasets as basic programming examples for future programming projects and knowledge building:
a Dataset Dashboard with graphs plotted with ChartJS to visualize information on the datasets stored in MongoDB;
a 2D map viewer web application with OpenLayers to plot geospatial data on OpenStreetMap and OpenSeaMap maps;
a 3D map viewer web application with Cesium to plot data in a 3D map projection with the map showing a terrain elevation model to get a nice visualization when plotting datapoints with a height coordinate. So it’s all about plotting (x,y,z) coordinates instead of just (x,y) location positions.
Building the Course VM is documented in the cookbook ‘Creating the GeoStack Course VM’.
The full GeoStack Course is documented in the following set of detailed Cookbooks and Programming manuals:
700+ illustrated pages in 11 documents: 6 Cookbooks for Installation and Data Science and 5 Programming Manuals.
About the 5 Programming Manuals: there is 1 manual for the Python Flask web application to get Crane and Route datasets from the MongoDB database and there are 4 manuals for the TypeScript/Angular web applications: 1 manual for the base web application and 3 manuals for the end-user web applications: Dataset Desboard, 2D Map Viewer and 3D Map Viewer.
Open Source Software
There is Source Code in Jupyter Notebooks (Python), in Python script files and in Bash Shell installation scripts.
Configuration files for the server software.
The program files for the web applications in TypeScript, HTML5 and CSS3.
Re-use of around 50 Open Source Software components: from text editors and web servers to geospatial software packages!
Open Content Videos
76 introduction videos, overview videos and tutorial clips to visualize the documentation, server software and web applications.
Follow the 8 Playlists on our YouTube channel, totalling to almost 90 minutes of video:
1 Playlist for the 2 Short Showcase videos: Introducing The GeoStack Project (1 min) and Presenting the GeoStack Project (6 min)
1 Playlist for a series of Overview videos.
6 Playlists for the 6 series of short Video Tutorial Clips.
Open Content Datasets for topographical maps
Re-use of topographical data from OpenStreetMap, OpenSeaMap and DEM (height) files for 3D Maps from the Dutch AHN dataset via PDOK.nl.
Open Content Datasets for map plotting
Re-use of GPS track logs of ringed common cranes (Grus grus) from MoveBank.
Use of 8 GPS track logs of car, bike and hike routes.
Re-use of the World Port Index dataset.
Free online Topographical Content Services
To learn how to work with web map services The GeoStack Project uses 4 free online web map services and also their web applications for testing.
Notice there are limits to the number of map tiles or map views per month for these free services but it is more than enough to learn how to program.
2D Maps: OSM web map service for (1) OpenStreetMap and OpenSeaMap maps and (2) Thunderforest to learn how to work with a service that uses an API key to access their maps. For Thunderforest you need to register a free account to request their API key.
3D Maps: for height maps (3) Cesium ION is used for the 3D web map services that provide an online Cesium Terrain Server pre-loaded with DEM height files and the option to visualize both topographical maps and aerial maps.
For the use of Cesium ION you need to register a free account.
The DEM files used in the Cesium ION Service are low resolution so the height profiles are not very accurate. Understandable because of the costs and that’s why the GeoStack course explains how to download and use these large high resolution DEM files.
In the GeoStack Cesium demo web app the (4) Bing Aerial maps are used as an example but there are other map options too.
All in all, the documentation and source code totals up to more than 1.000 pages to learn from!
And… complemented by many minutes of video!
And… with thanks for the re-use opportunities to the creators of the Open Source Software and publishers of the Open Content Datasets!
The Development Environment in this course will learn you about the following subjects:
1) Virtual Machine hosting: Virtualbox (Installation and Use).
2) The Linux Operating System: Ubuntu LTS (Long-Term Support version).
installation scripts are programmed as bash shell scripts;
there is also a small script written in Java used to create the links for the topographical map tiles between the nautical objects on them from OpenSeaMap and the nautical map icons to generate the map tiles for all the map zoom levels to store in the cache folders of the tile server.
deleting data(sets) with the database managment tool MongoDB Compass to clean up the MongoDB JSON document datastore.
11) Storing datasets in a SQL datastore: learn to use the RDBMS PostgreSQL in combination with the spatial PostGIS extensions for storing RAW OpenStreetMap data and storing geospatial data from ShapeFiles:
loading RAW OSM data in a database using OSM2PGSQL;
13) Creating a middleware web service with an API using the Python micro web services framework Flask and a Gunicorn webserver:
programming the middleware web application app.py in Flask to run the ‘business logic’ of data handling as a (micro) web service that is necessary to fetch data and pre-process it so the end-user web application can get the data to visualize from the API and plot it on topographical maps. This is where the magic happens!
connecting to the MongoDB datastores using PyMongo;
connecting to the PostgreSQL datastores using PsycoPG2;
executing queries on the datastores using among other things geospatial queries in combination with PyMongo and PsycoPG2;
transforming and serving the queried data, obtained from the datastores, to the front end (= end-user) web application.
This is provided to learn how to install the mod_security module and the basic OWASP security ruleset to secure all the GeoStack components running behind the NGINX web server by letting the mod_security module run the security checks.
SECURITY WARNING: do NOT run this configuration for production or other purposes when connected to the internet or any other untrusted network because this course shows just an educational setup with the basic OWASP ruleset!
It has not been checked if the configuration or ruleset is fit-for-use!!!
It’s just a basic installation guide and adding your own security rules is not explained!
YOU HAVE BEEN WARNED!!!
a 2D Map Viewer using the geospatial framework OpenLayers in which you can select multiple routes, animate routes, change map layer styles and much more;
a 3D Map Viewer using the geospatial framework Cesium in which you can visualize the datasets on 3D maps.

Work instructions –> GeoStack Workshop and Course
Start with the 1-day GeoStack Workshop by following the document Cookbook-Creating-the-GeoStack-Workshop-VM.pdf.
Here you will learn if you need to build some extra skills first.
After building the VM, start the file manager Nautilus by clicking the file cabinet icon on the left in the Favorites menu.
Then in the Home folder of the GeoStack account on the VM, go to the folder GeoStack-Workshop.
Follow the programming assignments in the file Cookbook-Workshop-Assignments.pdf.
Work through the full 10-day GeoStack Course by following the document Cookbook-Creating-the-GeoStack-Course-VM.pdf.
There are two ways of building the Course VM:
1 - Automatic installation by using the supplied set of installation scripts as explained in chapter 4.
2 - Manual installation by working your way through the large set of 8 detailed course cookbooks and manuals as explained in chapter 5.
Advice GeoStack Course: first build the Course VM the easy way with the installation scripts to explore and then do it the hard way by really learning some serious Systems & Network Management in building the GeoStack and programming the web applications!
Note: in the manuals on how to create the VM’s you will find detailed instructions about:
cloning the git repositories GeoStack-Workshop and GeoStack-Course;
creating the Virtual Machines and installing Ubuntu Linux and all the GeoStack software you need;
the download instructions for the GPS track log datasets;
the instructions to export, download and import the map and terrain elevation datasets required for visualizing digital topographical maps in OpenLayers and Cesium.
Download instructions –> GeoStack Project Files
Go to the top of the web page and click the blue button ‘Project Files’.
Save the large ZIP file GeoStack-Project-Files-master.zip of 570 MB (!) that contains the repository GeoStack-Project-Files.
Unzip the ZIP file which will give you the folder GeoStack-Project-Files-master.
In this folder you will find the subfolder GeoStack-Document-Files with the original ODT text editor files created with LibreOffice Writer as well as the document covers, diagram.net images, photos, the blue GeoStack ‘Clock-Compass’ logo etc.
The project files are provided for easy re-use content of Open Content.
Tip: if you want to copy a lot of source code then use the original ODT files because indentations get lost in a Copy & Paste from PDF files!
Tip: if you unzip an ODT file you find all the images of the document in the folder Pictures.
Lowering the Learning Curve
1) First of all: read the weblinks on this web page! They paint the picture! Then read the cookbooks, manuals etc.
There is a lot of documentation to explain what, why and how things work. Don’t be smart, read it first!
It will be reading time well spent! There is no ‘black magic’ left, once explained!
2) Second: study the installation scripts and example scripts!
There are also many installation-, import-, export- and conversion scripts to work fast and install and run without errors but also to help in learning how things actually work!
3) Third: remember in programming ‘a point is not a comma’!
Typos are easy to make, but finding them to correct can be really hard!
So first read carefully until you understand and only then grab your keyboard!
When coding: type slow and read your code back!
4) Finally: make copies of files before you change them!!!
If you want to experiment with building the VMs for the Workshop or the Course
then make a copy of the configuration files and the installation scripts and
document your changes with in-line comments to keep track of what you did!
Save new file versions in your Programming Editor before running them!
Keep the original files alongside to look at as the working examples!
So do not use the original files as you might end up with a broken VM.
Also do not make command line changes because they are by their nature
undocumented changes or you might end up with a broken VM.
The same goes for changes you want to make to code in Jupyter Notebooks or in
–> Make it a habit to use a file copy and you’ll be safe and save yourself a lot of time!
1) Educational goal: the software and content of this project are only intended to learn about programming geospatial dataset processing in Python and programming webapplications in TypeScript for the visualization of this geospatial data on digital topographical maps.
2) Software selection: this course focuses on creating an Open Source geospatial software stack, the GeoStack, to
develop and run webapplications for visualization of geospatial datasets. There are more Open Source Software products that can provide the same functionality as the products chosen in this course.
3) Complexity reduction: some well known software products are left out of scope in order not to complicate things more than necessary for an already fairly complex beginner course, like:
QGIS: a great Open Source geospatial desktop application! Recommended for geospatial enthousiasts after taking this course! Also very useful in exploring geospatial datasets. Left out because it takes a course in itself to learn QGIS.
Leaflet + Python Folium: Leaflet is a comparable geospatial webapplication framework to OpenLayers for generating 2D topographical map views and Folium is the Python wrapper module for it. Once you have learned OpenLayers in this course you have a good reference to explore Leaflet/Folium in order to find out what works best for your use cases.
cesiumpy: a Python wrapper module for Cesium, comparable to Folium for Leaflet. Left out because it is fairly new and still a concept version (currently 0.3). Therefore the 3D Map Viewer webapplication is programmed in TypeScript with the Cesium API.
Marble: as an Open Source Virtual Globe or World Atlas application for desktop and mobile very interesting to get some programming experience with because it also uses OpenStreetMap. Build some knowledge first with Cesium for 3D maps and then it’s time for Marble or programming with another virtual globe application like Google Earth.
GeoDjango: a geographic web framework for the Python Django web content management framework. Also fairly new and although Django is fast and runs large websites with ease it does have a learning curve!
Git: for version management of source code. Highly recommended for larger sofware projects and when working in development teams! The Open Source webapplication GitLab can be used to run your own Version Control System webserver locally.
Also out of scope are:
The geospatial functions of the two JSON document data stores of the No-SQL database MongoDB and the search engine Elasticsearch. Elasticsearch is build around and uses the geospatial functions of the Lucene core search engine.
Beginner documentation and programming tutorials on how to program with the Geopackage and GeoJSON file formats.
The creation of geospatial web applications for mobile devices with a focus on using the Geopackage file format.
Scope Note: software, installation and programming mannuals for the left-out-of-scope software and file formats mentioned above could be easily added to The GeoStack Project if volunteers would be willing to make them!
The document templates and original text editing files of the current GeoStack documentation are available in the repository GeoStack-Project-Files as ready-to-go templates for a quick start!
This programming course was originally created by computer science student Pieter Lems of the Rotterdam University of Applied Science (Hogeschool Rotterdam) as the result of his 3rd year Bachelor internship assignment (201909-202001) in practical programming for data scientists.
The internship was offered by the ICT innovation department of the Netherlands Ministry of Defense (MoD-NL/DMO/JIVC/KIXS).
Read the interview in Dutch about Pieter’s internship project here.
After his internship Pieter continued to contribute to this project as a volunteer software developer.
The first release of The GeoStack Project was published here on GitHub as Version 1.0 on Friday, October 9, 2020.
The motivation to create this course is to collect and combine all the very much fragmented information from many manuals, (video)tutorials, applications, programming languages and frameworks, file formats etc. into one documentation set for beginners in data science, programming and systems managment to learn to download, install, program and use all the software components and datasets in one logical workflow to get:
-----> 'Working Software at the End of the Day!' <-----

Please use the proper labels as described on the wiki page to tag the ticket for your issue accordingly!
Support is very limited, because this project is currently not an active open source project.
Expect at least several days of delay or more for a ticket response! Handling tickets is not a priority! Maybe we look once a week! ;)
Use the Issue Tracker to post a Ticket with the label ‘Contact’ if you want to request a personal conversation with one of the team members and also include information on the subject you want to talk about.
A free one-on-one secured JITSI meeting is an option for both a good quality voice call and the option to use the webcam too.
The name of the meeting room can be published in the ticket to avoid public exposure of personal contact information in a ‘Contact’ ticket.
Currently we are not accepting pull requests from GitHub users other than the current team members.
If you want to contribute to The GeoStack Project then post a ticket in the Issue Tracker with the label ‘Request’ or ‘Contact’ depending on what is suitable for you to communicate about what you would like to contribute.
New Team Members
The project is currently published as-is with a project team of only a few volunteers for very, very low maintenance without making any promises!
New team members are needed to make this project an active Open Source project because, with around 50 software and content components that will be updated over time, the project is expected to have a limited shelf life of around 12 months. Without maintenance the project will then need to be either archived or removed.
If volunteers are willing to participate in project maintenance and creating new course materials this project could become an active Open Source project.
So if you want to contribute some serious time to The GeoStack Project then post a ticket in the Issue Tracker with the label ‘Contact’ and the information on what you would like to contribute.
