Become a high-skilled geospatial professional

Sharing of open software tools and algorithms for hazard, risk & resilience is one of the aims of the CDR. We aim to provide tools for hazard modelling, python scripts for geo-processing, risk assessment etc. Some examples:


Lisem (Lisem Integrated Spatial Earth Modeller) is a free and open-source software tool that allows users to manipulate geo-spatial data. Featuring both simple operations and advanced algorithms, complex models can be developed. The tool features an internal scripting environment designed for easy data manipulation, a geospatial data viewer, and the LISEM model, which aims at simulation of Hydro-meteorological surface hazards. Additionally, the software comes with Python bindings that allow for interactions with other libraries and automization of code. Have a look at the documentation for more information on how to use and install LISEM.


A GUI for the freeware Geographical Information System PCRaster. This is an independent development. Comes with a map editor "mapedit". Can make a link with GDAL for conversions. The GIT repository is available linked to PCRaster and available here.


RiskChanges is an open-source Spatial Decision Support tool for the analysis of Dynamic Multi-Hazard risk. A Spatial Decision Support System (SDSS) is a “Interactive computer systems designed to support a user or a group of users in achieving a higher effectiveness of decision making while solving a semi-structured spatial decision problem”. An SDSS has an explicit geographic component; it is supporting rather than replacing the user’s decision making skills, and facilitates the use of data, models and structured decision processes in decision making. The RiskChanges spatial decision support system has been developed with the aim to analyse the effect of risk reduction planning alternatives on reducing the risk now and in the future, and support decision makers in selecting the best alternatives.
