Hi, I have twelve UK Ordnance Survey Mastermap tiles which I am trying to mosaic into one layer. If I load the images one at a time they look correct. If I use the Mosaic to New Raster tool some of the tiles do not preserve their colourmap.
I am using ArcGIS 10.41. Tiles are standard OS Mastermap Raster Local.
If I use the Mosaic to New Raster tool to import the twelve tiles I get the following:
River is now green, Bridge is wrong colour, Road changes from blue to grey, some field drains are no longer blue, some of the houses out of screen grab are blue.
I have tried importing colourmap, saving as .tif and saving as ESRI grid. To date no joy.
Any and all suggestions welcome as I am sure it is some simple mistake but I can not seem to find it.
