Introduction

Welcome to the wonderful world of the Geo Data and Model Software (GeoDMS). The GeoDMS is an opensource GIS modelling framework which can be used to make fast calculations in a controlled, transparent and reproducible way on (very) large (geographical) datasets.

The software is continuously in development and is, for example, being used by the The Netherlands Environmental Assessment Agency, the Joint Research Centre of the European Commission, the Vrije Universiteit Amsterdam and multiple Dutch municipalities.

Features

The GeoDMS is especially suitable for applications with one of more of the following characteristics:

  • modelling/analyzing with large geographical datasets, such as large grids, building registers, or road networks;
  • combining multiple calculation steps to reach a certain result;
  • parameterize calculation schemes to perform scenario analyses and compare their results;
  • discrete allocation under capacity restrictions, accessibility and network assignments
  • being able to reproduce and understand what you calculated last week, and transfer your methodology to your successor.

The GeoDMS is less suitable to:

  • make a fast (simple) thematic map. QGIS or ArcGIS are more suitable for this purpose;
  • manage data; a database of version management systems are more useful for this.

GUI and scripts

Working and modelling with GeoDMS consists of two components, the GeoDMS GUI graphical user interface (GUI) and a text editor.

The GeoDMS GUI runs a set of text files with the .dms extension. In these scripts all commands to read data, perform analyses and export outputs are specificied.

The GeoDMS does not support modelling data with menu options such as mainstream GIS software (QGIS, ArcGIS). All analysis steps need to be scripted in .dms-scripts.

Outline of this academy

In this section you will find a set of modules on how to learn to work with GeoDMS and use its scripting language. This GeoDMS Academy is structured in way that it enables you to accumulate the knowledge when you work through it front to back, or you can just dive into certain topics when you are already acquainted with the topic discussed in earlier modules.
