Hi Andrew-
>Hello, I am very new to IDV and displaying meteorological data. I am
>running IDV on Windows 2000 with IDV version 1.1b3 and Java 1.4.1_02.
Are you compiling from source or are you using the InstallAnywhere
installer?
>I am trying to display some GOES / GVAR data, along with some
>topological data in DEM or geotiff format. I am behind a firewall and
>proxy, so all my data is in local files. Below is a description of
>the errors and problems I am having, Any help or suggestions would be
>appreciated?
For local files the GVAR data must be in 8 byte, single band format
for the IDV to view. Even then, if your image is really big, there
might be a limitation where the image shows as a grey image only.
You can use the pixel spacing slider on the control to subsample
the image so it will fit in your graphics buffer.
The IDV does not support the DEM data from the USGS in the raster format.
It supports the USGS DEM format listed at:
http://rockyweb.cr.usgs.gov/nmpstds/acrodocs/dem/2DEM0198.PDF
The IDV support for GeoTIFF is very limited. However the error
message indicates that there is a missing JAR file in the distribution.
Thanks for bringing this to our attention. We will add that in the
next release which should be out in the next couple of weeks.
