7: Raster data processing

In this chapter, we will introduce how to conduct various data analysis and manipulation operations in Python using raster data. You will learn to use a few of the core libraries for raster analysis/processing, such as xarray and rioxarray. More specifically this chapter will cover:

• Introduction to raster processing

• Reading and writing raster data (Data I/O)

• Reprojecting raster data

• Mosaicing

• Raster resampling

• Map algebra – Doing calculations with raster data

• Raster to Polygon - Polygon to raster

• Masking / clipping

Sections:

• Introduction to raster processing with Python
• Reading raster files
• Common raster operations
• Raster operations between multiple layers
• Exercises
