I have combined MODIS blue marble images into a mosaic, a screen shot of the mosaic raster image with its source info opened in ArcMap is attached. The file source shows that it has angular coordinates defined. I tried to define projection/project but nothing seems to be working. My problem is that this image does not align with other layers having projections defined (e.g. basemap). So I need to align it with other global maps (e.g. basemap) so that it overlaps with them. I know the coordinates of all the four corners of the map (e.g. bottom left corner is -180, -90 or 180W, 90S). I thought it should be a simple problem of georeferencing but it does not seem so after searching all the information online. How can I project or georeference this image in a simple way using the tools in ArcGIS? Please help.

If you need to align your raster layer by coordinates or several known points, you can find the georeferencing toolbar in arcgis Desktop (online help here). I had already test that to put a none spatial picture (like old urban plan) on basemap. I hope i helped you...

So I georeferenced it using georeferencing tool. I used the four corner coordinates as the control points. I used: WGS84 Bounds: -180.0000, -90.0000, 180.0000, 90.0000 Projected Bounds: -20037508.3428, -10018754.1714, 20037508.3428, 10018754.1714
