This tutorial is an introduction to the basics of map algebra. To teach arithmetical and logical operations, the tutorial demonstrates how to use map algebra to generate a landscape with mountains, plateaus, forests, valleys, and rivers. Since this tutorial generates synthetic data, it does not require an existing dataset. It is designed for a temporary project in an unprojected xy Cartesian coordinate system. Since it is the first of a short series of map algebra tutorials, it has a new map algebra directory and contains an images subdirectory. There are 11 200x800px images in
.webpformat totaling 1.2MB. Images were designed in a landscape format to fit the width of the webpage layout. The next tutorial will be advanced map algebra with Python covering topics such as string formatting, moving windows, randomness, neighborhoods, and evaluation.
