[GRASS-user] trouble transforming corine landcover raster projection Lambert laea to lcc

[Patrick Giraudoux]

Hi,

I  wonder if this list is the right place to ask for help on such a 
subject since the trouble met can well come from projection definition 
error rather than GRASS itself. Anyway, I have a trouble trying to 
transform projection from one system to another. Within a location 
called corineurope I have extracted a subset of the corine landcover 
2000 data set 100m resolution (whose projection is given below). This 
subset corresponds to a window including the Franche-Comte region 
(geographical sense). I have created another location in a French 
coordinate system called "Lambert II etendu", the region (GRASS sense) 
including the whole country.

However,  what I get  is just the following sequence:

GRASS 6.0.2 (franceLIIe):~ > r.proj input=fc location=corineurope 
mapset=giraudoux output=fc

Input Projection Parameters: +proj=laea +lat_0=52.0000000000

Output Unit Factor: 1
ERROR: Input map is outside current region
GRASS 6.0.2 (franceLIIe):~ >

The error message is clear, but after many checks about projection and 
region definitions, I cannot find what is wrong.

Any suggestion appreciated.

Thanks in advance,

Patrick Giraudoux
