Hi Rainer I'm not sure where Keurboom nature reserve is, but South Africa uses transverse Metacor. So it probablity one of the following projections, just the +lon_0 changes.
+proj=tmerc +lat_0=0 +lon_0=25.00000000000003 +k=1 +x_0=0 +y_0=0 +ellps=WGS84 +towgs84=0,0,0,0,0,0,0 +units=m +datum=WGS84 +no_defs +proj=tmerc +lat_0=0 +lon_0=27.00000000000003 +k=1 +x_0=0 +y_0=0 +ellps=WGS84 +towgs84=0,0,0,0,0,0,0 +units=m +datum=WGS84 +no_defs +proj=tmerc +lat_0=0 +lon_0=29.00000000000003 +k=1 +x_0=0 +y_0=0 +ellps=WGS84 +towgs84=0,0,0,0,0,0,0 +units=m +datum=WGS84 +no_defs +proj=tmerc +lat_0=0 +lon_0=31.00000000000003 +k=1 +x_0=0 +y_0=0 +ellps=WGS84 +towgs84=0,0,0,0,0,0,0 +units=m +datum=WGS84 +no_defs Lester On Tuesday 05 July 2011 12:52:01 Rainer M Krug wrote: > Hi > > I have two shape files of which I do not know the projection (and it seems > that the person I got them from does not know either...).
