Dear all,
I have a shape file tha for a certain reason has wrong coordinates.
The areal geometry data originally come from a dgn file with EPSG3004
coordinates, but now as I edited and exported from Geomedia, they have been
multiplied for a factor 100, ie the exported shape has coordiantes 100times
greater than real ones.
How can I go back (re-translate) to EPSG3004 coordinates?
I saved a custom CRS ading to EPSG3004 string,the keyword +to_meter=0.01 ,
but it doesn't work.
EPSG:3004 is defined as:
+proj=tmerc +lat_0=0 +lon_0=15 +k=0.9996 +x_0=2520000 +y_0=0 +ellps=intl
+towgs84=-104.1,-49.1,-9.9,0.971,-2.917,0.714,-11.68 +units=m +no_defs
If you want to change the units, you have to replace the +units=m part
with +to_meter=0.01:
cs2cs +proj=tmerc +lat_0=0 +lon_0=15 +k=0.9996 +x_0=2520000 +y_0=0
+ellps=intl +towgs84=-104.1,-49.1,-9.9,0.971,-2.917,0.714,-11.68
+to_meter=0.01 +no_defs +to +init=epsg:3004 <in.csv >out.txt
in.csv:
250000000 450000000
out.txt:
2500000.00 4500000.00 0.00
HTH,
André Joost
