Input Data
Please select one
Option  1
Option  2
Option  3
Option 1:
Method based only on maps, photos, or GIS analysis (may include panchromatic, true color, color IR photos; multi/hyperspectral data; satellite imagery).
Option 2:
Method based on field data - may include GIS component.
Option 3:
Method based on field data - may include GIS component and requires lab analysis or taxonomic analysis subsequent to field collection.
