Routine psmile_transform_extent_cyclic(grid_type,
extent, transformed, tr_codes, n_trans, ierror)
The routine transforms the extent
"extent" of a
grid of grid type
"grid_type" into the common coordinate system and subdivides the extent
corresponding to the cyclic behaviour of grid type "grid_type"
grid_type,
extent = in
transformed, tr_codes, n_trans, ierror = out
The routine assumes that :
- longitude range is within interval (-3*180:3*180)
- latitude range is within interval (-3* 90:3* 90)
and maps the data into the range (-180:180, -90:90)
When all the grids on all the components will be in the same common
space, it will be possible to search for intersections.
get in entry the extent of the grid "extent" in the 3 directions of
space.
return an array "transformed" into the range
(-180:180, -90:90).
