Dear list,<br>
I used the geoprocess "reproject" in order to change the projection of
some layers from ETRS89 to Gauss-Krüger and observed some <br>
strange things:<br>
a) the size of the dbf-file of the shp was much bigger after the
reprojection was done. I checked the field properties of both the
source and target layer and <br>
found that the field length was set to 18 for all columns, while the
original columns had different field lengths (5 or 8)<br>
b) there are several options for transformation within this geoprocess.
I got the best result, when I chose "no transformation". However, the
reprojected shapefile did not 100% fit<br>
to the correct location in the target projection. There's a little
shift of a few meters (x and y). Of course, it is possible to shift the
whole layer a bit, but this is not a "clean" method. Shouldn't it fit
with only reprojecting the layer? <br>
c) Choosing the option "manual transformation", I have the possibility
to set x- and y-translation, but the result was <br>
not what I expected: specifiying 10 for x- and y-offset did not result
in a equal shift of 10 meters in both directions. The distance in both
directions was bigger!<br>
c) when choosing EPSG transformation, several possibilities are listed,
but the description was not clear to me. I just did not know which
option to choose. Hopefully, the enclosed screenshot will explain
better what I want to say here ;(<br>
I searched for some information in the user manual of version 1.1.x,
but the description there is not exhaustive. Some information on how to
use this nice extension would be great.<br>
<br>
Best,<br>
