[GRASSLIST:3597] Geocoding a Lambert Conformal Concentric raster.

[Martin Stephens]

I am running GRASS 5.3.

I have a raster map draw on the Lambert Conformal Concentric projection, wgs 84 spheroid / datum. I have followed the tutorial and have imported it into a location in the XY projection.

Now I need to create a location in the LCC projection to geocode the raster with i.rectify. My problem is that the known points on the raster map are long / lat. When I create the LCC projection with units as degrees I am asked for a conversion factor for metres.

Can I just enter a conversion of 1m for 1deg and then enter the locations in i.point as degrees? If I have to provide a conversion factor for degrees to metres how do I calculate this?

Thanks for any help.
