If you're getting into details, it might be useful to define what's meant by minimum and maximum - presumably the response isn't tightly bounded but tails off? > - Geolocalization: we have quite a lot of data that is easily represented on a > grid, but the CF-convention requires the grid of lons and lats to be > calculated. > This is of course highly inconvenient for fixed grids (from a data storage and > transfer perspective). We suggest adding a proj-string (proj.4 string As I understand it, the CF convention allows you to specify regular grids as two 1D lat and long coordinate axes. If you've got that case, the data storage isn't as bad as full 2D grids. On 25/08/10 08:32, Martin Raspaud wrote: > I agree with you that including lat/lon is useless when providing a > projection.

It can be useful for those of us who are too lazy to implement the computations ;) Cheers, Mike. -------------------------------------------------------------------------------- Plymouth Marine Laboratory Registered Office: Prospect Place The Hoe Plymouth PL1 3DH Website: www.pml.ac.uk Registered Charity No. 1091222 PML is a company limited by guarantee registered in England & Wales company number 4178503 -------------------------------------------------------------------------------- This e-mail, its content and any file attachments are confidential.
