Hi!
I have to convert a pair of geographic coordinates in wgs84
to epsg:3035 (GRS80 ellipsoid). Where can I find the appropriate
towgs84 parameters? This is to set the NW corner coordinates
of a tifw file for a tif file with elevations of Europe in epsg:3035 projection
(http://www.eea.europa.eu/data-and-maps/data/digital-elevation-model-of-europe)
A *.tif.xml file provides geographic coordinates for the NW corner (
-38.04824, 72.66958) but have to convert
to epsg:3035.
Hi Agus,
What precision do you need ? WGS84 and GRS80 ellipsoids are not very
different.
Jean-Claude
