I have a netCDF file of fire emissions on a regular grid of 12 km by 12 km grid cells with 200 east-west grid cells by 161 north-south grid cells centered on the continental United States. The map projection is Lambert Conformal. I am using QGIS v1.8. When I open the raster it displays as a very, very tiny raster located in mid-northern reaches of the State of Kansas. Can someone tell me what blunder I am performing?

    Sounds like a projection error. What exactly is the projection of your grid?

  • There are lots of lcc projections defined for Northern America. I wonder how the data can cover the whole US with that. Apart from choosing the right one, there are also some projections in feet instead of metres.

Perhaps units? The grid seems to be 12km*(200x161)= 2400km x 1932km, while the continental US is closer to 5000km x 2500km.

If "very, very tiny" is on the order of 2.400km x 1.932km, it may be a km vs. m units problem as well.
