Hi,

I just made another observation: when changing the units of the projection_?_axis from m to km, the results are stable and stay those of the first try.

Hi,

I have a file with gridded polar-stereographic data in CF-1.0, which
shows nicely in IDV. When putting the file on thredds and requesting WCS
GetCapabilites, I receive the following:

First try:

<lonLatEnvelope srsName="WGS84(DD)">
<gml:pos>-77.0 43.95245311362685</gml:pos>
<gml:pos>103.0 43.95245311362685</gml:pos>
</lonLatEnvelope>


Second try:
no envelope

Third try:
<lonLatEnvelope srsName="WGS84(DD)">
<gml:pos>-32.0 90.0</gml:pos>
<gml:pos>-32.0 90.0</gml:pos>
</lonLatEnvelope>

And it stays at the values of the third try, which are the definitions
of the projections (polar-stereographic, view at -32 degree) rather than
the envelope.

The data spans over the northpole, so longitude is from 0-360 while
latitute starts at 90 and has a minimum value of 43 degree.

The file can be found at ftp://ftp.met.no/pub/emep/heikok/testShort.nc
(1.6MB)
I'm running thredds 3.16 on linux with java 1.6 and tomcat 6

Does anybody know how I can solve the problem of the wrong envelope?

Best regards,

Heiko
