----------------------------Original message---------------------------- Is there anybody out there who can supply reliable conversion formulae - or the relevant constants and parameters - for converting map data (Arc/Info coverages and ArcView shape files), in both directions, between Irish Grid coordinates and UTM; and also between Irish Grid and geographic (latitude and longitude) referencing? Thanks!
