[Qgis-user] Export to new Projektion

[Claas Leiner]

Hi, thanks for answer

the parameters are

ETRS89 / UTm32:
+proj=utm +zone=32 +ellps=GRS80 +towgs84=0,0,0,0,0,0,0 +units=m +no_defs

wgs84
+proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs +towgs84=0,0,0

DHDN GK3:
+proj=tmerc +lat_0=0 +lon_0=9 +k=1 +x_0=3500000 +y_0=0 +ellps=bessel 
+towgs84=582,105,414,1.04,0.35,-3.08,8.3 +units=m +no_defs

 From ETRS89/UTm32 to wgs84 and then to DHDN GK3 the result ist right
In one Step From ETRS89/UTm32 to DHDN GK3 the result ist wrong.
