Sometimes there's a need for processing data sets related to geographic information, e. g. locations. For example, you might want to calculate distances between customer addresses and your shop.

Over the last few weeks, I prepared some processes that solve common GIS tasks. They use the GeoScript project's libraries and RapidMiner scripting. You might find this functionality useful.

Part 1 describes the basics of Geographic Information System operations and the installation of GeoScript in RapidMiner studio:

Part 2 is about importing Shapefiles, a popular file format in GIS circles:

Part 3 describes distance and area calculations:

Part 4, the last one for now, is about joining and filtering data sets using geographic criteria:

Feel free to ask if something is not described clearly enough. I'm also really curious about the use cases people solve with this, so please post your results!

Cheers

    GeoScript is a frontend for scripting languages.

    The backend is GeoTools, a Java library. If you want to write a native extension for RapidMiner, you can skip GeoScript and go straight to GeoTools.

    I posted a new tutorial for displaying geographic data (points, lines, areas) in RapidMiner Server dashboards/web apps:
