its been some time since I have done some mosaicing in ArcMap and I am finding some difficulty. I have 6 rasters that I would like to merge into one file so I can serve them out as one map using geoserver. They are currently geotiffs or png's. The maps are at angles relative to one another so I am running into issues with null values.
at places where the images overlap I cannot get a good result. either its white, black, or the wrong values. since the inputs are png there is an alpha of 0 or 255. can someone help me merge them together?
attached is what I am getting and what I would like.
this is the result
this is what I would like
