[gdal-dev] DTED Elevations with Java and gdal

[Kyle Shannon]

Check the code for gdallocationinfo app.  

Docs for the app:

http://gdal.org/gdallocationinfo.html

code for the app:

http://trac.osgeo.org/gdal/browser/trunk/gdal/apps/gdallocationinfo.cpp

That should get you started.  I assume the java bindings are up to date.

Subject: [gdal-dev] DTED Elevations with Java and gdal

There have been other threads on this topic.  The threads seem to die with no clear solution presented. 

Does anyone have a Java example on how to get elevations from a DTED file? 


org.gdal.gdal.Dataset dataset = org.gdal.gdal.gdal.Open(<some dted file>, org.gdal.gdalconst.gdalconst.GA_ReadOnly);


With an x y point how can the elevation be derived?


We have been able to run GDALtest.java against a DTED file with no problem. 
There does not seem to be any reference to any elevation in DTEDtest.java

Just want to get the elevation at a point.



Thanks,

Roger
