How would I convert a raster map to a georeferenced vector or include it in analysis? – February 5, 2023 at 06:08PM

A community I’m part of is trying to find where to buy land for a homestead. I was hoping to practice some GIS and do some divergent thinking by doing an analysis of locations. Trying to find the right rainfall, temperature, growing conditions, political climate, proximity to services.

I can’t find a USDA plant hardiness map in vector, so I don’t know how to have GIS analyze it. Just georeferencing the image seems time consuming and prone to error.
