Predictor Variable Data

There are a large number of potential predictor variables. These should be ones that are logical.

1. Satellite and aerial data
2. LiDAR
3. Digital Elevation Models
4. GIS data
5. Derived layers

Quite often you will not find a direct predictor such as "water availability" for plants but you might find precipitation.
