java applet and data in metric coordinates
Dear LAS users,
I am currently assessing how a combination of OpenDAP freeform server + LAS could suit our needs for serving NOAA AVHRR data specifically processed for us (mainly the map projection is very unusual).
OpenDAP is working fine, so I try to access it via the LAS.
I described the dataset in a noaa.xml file included in las.xml.
I also created a custom ui xml file.
I copied these files at the end of my email.
My problem are
1) when I reach the Constraints page, the java applet does not allow me to select an area. The values displayed for latitude are correct (from -2275900 to 2044900 m) but for longitude, it always remains blocked at 20E. I can not change this value in the text boxes and I can not draw anything in the java applet
2) if I select the "no applet" version, I get an exception from tomcat.
Could you please give me some suggestions ?
Below are the characteristics (size) of the file I want to serve and my custom ui and las include xml files.
Best regards,
Paul
