I have a project containing a KML file that presents points on a map, and a .tif file that appears as raster data showing the crops grown on a certain pixel. I was hoping to convert the raster data into polygons by identifying specific crops with select by attribute. However, I am new to GIS and I'm struggling to 1. see any evidence that pixels have been selected and grouped into polygons 2. Am not entirely sure what the next step would be. Ideally I hope to have all of the agricultural land (crop pixels) enclosed in polygons so that I can compare that to the points shown by the KML file. Any help would be greatly appreciated. Thank You
