Chapter 2. Identifying the Best Places

In this chapter, we will take a look at how the raster data can be analyzed, enhanced, and used for map production. Specifically, you will learn to produce a grid of the suitable locations based on the criteria values in other grids using raster analysis and map algebra. Then, using the grid, we will produce a simple click-based map. The end result will be a site suitability web application with click-based discovery capabilities. We'll be looking at the suitability for the farmland preservation selection.

In this chapter, we will cover the following topics:

• Vector data ETL for raster analysis
• Batch processing
• Raster analysis concepts
• Map algebra
• Additive modeling
• Proximity analysis
• Raster data ETL for vector publication
• Leaflet map application publication with qgis2leaf
