Hi
I want to resample a grid in lat/lon to a grid in a projection and do the
transformations myself. Both grids has a rectangular topology and the
projection grid has also has a rectangular geometry. Then, what will be most
efficient:

1
Transform all lat/long coordinates to the projection (forward transform) and
resample the data to the projection grid (in "projection space")

2
Transform the projection grid to lat/lon (inverse transform) and resample
the data to this transformed projection grid (in "lat/lon space")

If someone has some input to this and/or to how to resample most effective I
will be happy.

As I am using GRIB data and have a Java GRIB reader (JGrib of course, look
at sourceforge), I would like to know how to make a "GRIB adapter". Does
anyone have input to this?
