[GRASS-user] Mercator projection

[Steve Smith]

I am attempting to reproject data from a lamber conformal conic (lcc) projection to a mercator projection. The reproject appears to go well. The output is listed below. However, when I attempt to display the data I get the message: The bounding box of the map is outside the current region. So I use g.region to change the bounds of the region to: 50, 20, -40, -100, but I still get the same error message. As a test, I created another Location, this time as Global LatLon, and after reprojecting the data, from my lcc projection, I was able to display the data, after changing the bounds of the region to the values above.  This makes me think that there is something wrong about my mercator projection. When I run v.info on my data the projection info is:

Projection: x,y (zone 0)                       
           N: 4370846.189    S: 3988531.316                                
           E: -8414703.985    W: -9288507.105                              
           B: 0.000         T: 0.000 

It does not say I have a mercator projection?  When I created the location, I selected merc as my projection, declined to select a datum(wgs84 was used by default), and then when it asked for an ellipsoid I selected sphere, with the following settings:

lat_ts=0, lon0=0, k=1, a=6378137.0, north=85.05112878, south=-85.05112978, west=-180, east=180, nsres=0.00000904, ewres=0.00000898
