Advanced Geospatial Modeling
In this chapter, we’ll build on the data processing concepts that we learned about in the previous chapter in order to create some full-scale information products. The previously introduced data processing methods rarely provide answers to questions by themselves. You can combine these data processing methods to build a geospatial model from multiple processed datasets. A geospatial model is a simplified representation of some aspect of the real world that helps us answer one or more questions about a project or problem. In this chapter, we will introduce some important geospatial algorithms that are commonly used in agriculture, emergency management, logistics, and other industries.
The topics that we will cover are as follows:
- Creating a normalized difference vegetation index (NVDI)
- Creating a flood inundation model
- Creating a color hillshade
- Performing least cost path analysis
- Converting the least cost path to a shapefile...
