I am trying to project the ESRI OpenStreet raster map from WGS Auxillary Mercator projection to WGS 1984 geographic coordinatesystem. This is to be used within a third party application ( NOT ESRI!) in which the WGS 1984 geographic system IS REQUIRED.The third party application cannot project on the fly.therefore I must reproject the image. I´ve tried using the project raster tool which uses the NEAREST resampling method. The image appears blurry and unnoticeable.
Projecting this raster takes a long time so Can some please advise on an appropriate methodology?
