Hello all,

I have downloaded a DTM from Geomatics that comes in tiles (.asc) and when i put these into GIS and mosaic them together they become a FGDBR file. It enables me to load the individual tiles into ISIS but not the mosaic file. I have tried converting it to an ascii file on GIS but it then creats a .prj file. Does anybody know how I get the mosaic raster into ISIS?

Any help is greatly appreciated! Thanks

Hi Jess,

have you tried "mosaic to new raster" in data management tool in ArcGIS? With this tool, you can create a single raster from your tiles which you can then convert to .asc file. I can load .asc files with .prj files into ISIS. The .prj file stores information about the spatial reference of the data and should not be a problem.
