Topic outline

  • Introduction

    In this course you'll learn an essential skill for researchers dealing with (spatial) data. With scripting you can better control your analysis using command line tools. You can also automate your procedures by writing batch scripts. Furthermore, you can process your data and make models using Python and its useful libraries.

    The online learning course on Programming for Geospatial Hydrological Applications is part of the Climate Services for Water Management (CliMWaR) project, funded by the Flemish UNESCO Science Trust Fund (FUST) from the Government of Flanders in Belgium.

    The course is also available at the UNESCO Open Learning platform.

    The course materials have been last updated on 19 July 2023.

  • Module 3: Map Algebra in Python

    • In this module you'll learn how to perform map algebra using the PCRaster Python library.

      There are three Jupyter Notebook tutorials:

      • Map algebra for finding inaccessible wells in a study area
      • Interpolation of borehole data using Inverse Distance Weighting (IDW) and Thiessen methods
      • Stream and catchment delineation

      After this module you'll be able to:

      1. Explain the concepts of map algebra
      2. Convert rasters using GDAL in Python
      3. Use PCRaster in Python for map algebra
      4. Use PCRaster for interpolations
      5. Use PCRaster for stream and catchment delineation
