- Using Pro 3.1.1
I need to locate specific infrastructure on a 3m resolution DEM. The specific infrastructure are dams throughout a county. Naturally, I went through the usual hydrology tools to narrow down search area to the stream network within the county, and I began by using the masked Extract by Attributes on a Drop Raster because it seemed like the best choice. The search did locate most of the dams (I have a validation data set), but it also located thousands of other false positives. What other tools or code is available to further refine the search to only locate the dams?
Perhaps a better question would be how can I include more search criteria in the process? For example "locate only cells that are grouped adjacent to each other with high threshold values" and/or "locate only cells that are within a short distance (say 3 meters) from a large water body" (which could be the expected reservoir upstream of the dam).
I am a novice with Python (teaching myself in spare time), but was also exploring the Raster Cell Iterator as a potential. Good idea/bad idea?
