I want to merge many landuse raster data. Each raster file has its own different kinds of landuse type.    When I try to merge all of them (I have like 30+ raster files) the "Mosaic to New Raster" tool gives me an output with only 4 (the minimum number of unique values in one of the raster files) types of landuse file.  I also tried using… (Show more)

How can I get complete bounding polygon of XS CutLines for flood plain mapping (Flood Inundation Mapping) using HEC-GeoRAS and ArcMap 10.3? When I tried to perform this task, the bounding polygon formed was in an unexpected manner:   I want to get the bounding polygon without the gap that is visible around the river junction.

I am using a practice data set to practice the delineation of watersheds. I have been following the manual and so far everything is going well.
