QA/QC on LIDAR DATA ?
By Svenne68,
Hi out there,
I have been tasked to do comment on the quality of a LIDAR product. But the only thing I've got is a "point cloud" as a shapefile and no other information. There is no metadata or text in the description.
How do I do the QA/QC then ??
Raster to polygon random figure
By phanteon,
Hello guys I've got this map which I have to convert into shapefile. Each zone represented with a different color must be transformed into a polygon. (Feature) I know I can create features manually, that I have to many Maps and some of them have too many polygons that need to be created. I already tried raster to polygon in arcgis. But it creates waaay to Many polygons and the result is basically useless. Please tell me about any method you may know. Thanks
