Cursory?!!! I have spent hundreds of hours analysing government trail data from many different agencies, as well as mapping trails in OSM, and attempting to provide feedback to government agencies! I worked with a local TV news station on a story about the problems with government trail data: Colorado preferred trail navigation app COTREX has its own flaws, hikers say - CBS Colorado. I am offended that you call that cursory. I have made many videos documenting my findings that I have posted on YouTube. Here is just one playlist: https://www.youtube.com/playlist?list=PLjNfa27uVmKjX4baod9JHSQhEaXuCCFUM
I presented about my work at a major GIS conference this fall.
I research these issues in depth, often looking at documentation from the agency beyond their GIS data, as well as visiting many trails and taking geotagged phones of signs, recording GPS traces, etc. I am not “throwing darts”, I am only reporting the evidence that I have uncovered. Why does this bother you?
