I have two DSM rasters, one is 10km radius photogrammetric data, the other is 2km radius LiDAR data, both centred around the same point.
I need to combine these together, essentially inserting the 2km LiDAR raster into the other and removing that portion of the photogrammetric data, the idea being that the LiDAR is much more detailed in the area closest to the centre and the site that I'm working on.
I've resampled the photogrammetric raster to match the LiDAR so the cell sizes are the same.
What is the best way to go about doing this? I think it's using 'Mosaic to New Raster' but can't get my head around whether to use FIRST or LAST
