[mapserver-users] convert projection from UTM to WGS84 using proj

[Murat Beyhan]

Dear Jorn Vegard,

thanks for this help I have done it and I obtained DD WGS84 shape file
but problem the data which I study on it goes 3 degree east of the
actual places. I mean 3 degree shifted on the longitude. So how can I
ignore  this problem. 

here is command: 

ogr2ogr -s_srs "+proj=utm +datum=European_Datum_1950 +epsg:4230
+zone=37" -t_srs "+proj=latlong +datum=wgs84 +epsg:4326"  mahalle1.shp
mahalle.shp

thanks
