[gdal-dev] Vaisala IRIS format driver

[Roger Veciana i Rovira]

Hello Roberto,

The driver reads IRIS products, not IRIS raw data.
If I understand well your problem, you are trying to read the direct
information from the radar, stored in azimouth, distance, and antenna
elevation. The driver is intended to read the procesated rasters already
projected and with constant altitudes.
The driver opens your file since I think that the header is common in some
parts, but of course, can't find the projection if the data is no actually
projected.
Have you tried with some CAPPI, PPI or similar product?

I'm really interested in having some feedback with this, so ask as much as
you need.

Roger
