Antonio, What you could do is, first inversly project from UTM29 to lat, lon and then reproject to UTM30. For vector data, GMT http://gmt.soest.hawaii.edu/ has a module mapproject that will do the job. If you go to the source code, you will see the formulas from snyder are all there. I suppose the cartographic projection library PROJ.4 http://www.remotesensing.org/proj/ has the same formulas.
Hope it helps. Alejandro Hinojosa At 01:35 PM 11/14/01 +0100, you wrote: >Dear users, > >I am trying to get the manual " Map Projections - A Working Manual" by >John Snyder.
