Hi, What I want to do I thought was quite simple! I have a image array of data that has been mapped to a UTM projection (zone 32, ie longitude centre 9degrees). The map resolution is in kilometers - each pixel is 5km in size. I know the centre pixel latitue and longitude (and UTM co-ordinates), but not the lat,lon of exery pixel only their UTM position. I want to overlay a map using the MAP routine, but using the mercator package I can only specify max and min lat and lon - or a centre and zoom. There appears to be no way to specify the limits in other ways. Even if I did get the max and min lat,lon for the array, would this still produce a correct map as in UTM the array is not parallel to lat/lon grid lines? many thanks andy
