Hi all, I am brand new to QGIS and have pretty minimal GIS experience, so I apologize for my crude terminology. I was recently handed a large number of ARCInfo files (adf) containing information on species abundance at 30 m2 resolution. Each file (well...group of files since they are adf files) describes the abundance of a single species. I would like to analyze single species density within a custom-defined polygon. Species abundance within a 30 m2 is defined by color intensity (black = 0 abundance, white = max abundance).
I have figured out how to view single adf files as raster layers in QGIS. >From there, it seems like I should be able to generate a polygon and tell the program to analyze pixel count for each level of color intensity. I haven't had much GIS training, but I would really like to conduct an experiment that needs this data. Could someone please point me in the right direction? Thank you for your time, Aaron [email protected]
