If you look at the explanation of each site in the link in the base message, you'll see that specific applications like fish spotting, wild fire reporting, cloud sampling and so forth were not addressed. The FAA is after information on integrating UAS into the national airspace system (NAS), proving radio link dependability, looking at operations in various climate and terrain types and so forth. As you already know, there are all kinds of people chomping at the bit to apply accepted practices to their area of interest, such as photography, aerial application, wildlife spotting and counting the numbers of cattle in a feedlot. 😉
