I'm looking for solutions to this in ArcMap 10.2.2 Basic, with no Spatial Analyst extension.
I am trying to find parcels that have been damaged by a large fire. I have a raster image showing the burn path and surrounding areas. I'm overlaying a parcel layer on top of the raster and would like to extract polygons on top of raster cells that have a specific RGB range.
The dark red and black pixels always have a red value > 180 and < 210 with green and blue values less than 50. The lighter pixels all have RGB values > 200.
The raster has no attribute table as it is a multi band image. I converted it to a single band but the values are no longer discernible in the burn path from other areas of the image.
I then tried converting the raster to points. Still, no distinct values for the burn path.
Is there a way to select polygons using a specified pixel RGB range?
