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. <br>
</div>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.<br></div>Have you tried with some CAPPI, PPI or similar product?<br>
<br></div>I'm really interested in having some feedback with this, so ask as much as you need.<br><br></div>Roger<br></div><div class="gmail_extra"><br><br><div class="gmail_quote">2013/4/30 Roberto Oliveira Santos <span dir="ltr"><<a href="mailto:roberto@geodev.com.br" target="_blank">roberto@geodev.com.br</a>></span><br>

<div><br></div><div>I tried to use it against the volumetric data and it reads all metadata from file but does not bring any information about reference system, origin and pixel's size.
