Hello,
I am brand new to GIS and have been working with it in order to complete data analysis for my thesis research. I have had zero formal training thanks to COVID and have been learning as I go through online resources but I am struggling at the moment. I am currently trying to use the NHDplus to match COMID with my sample sites in order to use the StreamCat dataset to obtain catchment scale environmental data. I'm sure this is something quite easy to accomplish but I can't seem to figure it out. So I guess my exact question is, how do I go about obtaining the COMID for specific sample sites?
Thanks in advance for any help.
