Hi everyone, I am working on a tree crown delimitation project with lidar data. Everything is going well but at some point, it just seems I can't use the query builder in the con tool. I've used it in steps before this point so I don't know where the trouble might be.... Here are the steps thus far: invert canopy raster (Math/Negate tool) - tree peaks become ponds - branches/crowns become watersheds Smooth inverted raster (Filter) Determine local minima - focal flow to extract tree tops (Con tool, VALUE = “255”, if true, return Inverted raster Remove lowest trees (< 7 meters) --> here comme the trouble, trying to use the con tool, I don't have access to the data in the Query Builder of the con tool!! Any help would be appreciated! Thanks!
