I have a county where there is some LiDAR (1 meter) coverage. For the rest of the county I downloaded 10 meter DEM from USGS. Both rasters are in same projection and units. I resampled the 10 meter to one meter and Mosaic to New Raster to produce one seamless raster for the county.
Need to get Zonal Statistics for parcels, and it keeps missing some parcels, I read some suggestions are convert to tif and resample so small parcels don't get omitted. So trying multiple analysis and always get 999999 error. These include:
(From Catalog) Export Raster to Different Format: TIFF
Spatial Analyst: Slope
Spatial Analyst: Aspect
Should I try new mosaic? Seems to me like my merged raster is corrupt in some way but I don't know how to best fix it.
