  • A World of Projection Distortions

    We discuss common map projections and projection distortions.

  • Applying Map Algebra – Part 2

    This is the second in a series of articles on applying Map Algebra to solving problems. In the last installment, I discussed beginning to develop a habitat model as an example through which to apply map algebra. Now that there is a defined study area, it is time to dig into the model itself.

  • Applying Map Algebra – Part 1

    Over a series of blog posts, we will take a look at map algebra functions (that are currently or will be soon incorporated into GeoTrellis) by creating a site suitability model using wildlife habitat preferences.
