[Qgis-user] why is EPSG:2180 not recognised?

Hello,

I agree.
Other examples :

WGS72 (EPSG 4322)
----------------
The QGIS database contains :
+proj=longlat +ellps=WGS72 +no_defs

It should be :
+proj=longlat +ellps=WGS72 +towgs84=0,0,4.5,0,0,0.554,0.219 +no_defs
(look at <http://proj.maptools.org/gen_parms.html#towgs84>)


Guadeloupe 1948 (EPSG 4622)
---------------------------
The QGIS database contains :
+proj=longlat +ellps=intl +no_defs
It should be :
+proj=longlat +ellps=intl 
+towgs84=-472.29,-5.63,-304.12,0.4362,-0.8374,0.2563,1.8984 +no_defs



Martinique 1938 (EPSG 4625)
---------------------------
The QGIS database contains :
+proj=longlat +ellps=intl +no_defs  <>
It should be :
+proj=longlat +ellps=intl 
+towgs84=126.93,547.94,130.41,-2.7867,5.1612,-0.8584,13.8227 +no_defs


Conclusion : Don't trust the EPSG database, allways check the parameters.
