Use of multiple DTED files for a single WCS source

Hi,

I am trying to use an elevation map containing hundreds of .dt1 files for a single WCS source.

I managed to do it with a single .dt1 files but I don’t know how to do it with multiple .dt1 files.

I try to test it with an app that consumes the WCS data for a given area.

Is it possible to do it or am I missing any previous transformation?

Any help or indication is appreciated, thank you.

Kind Regards

Yes, it’s possible, you’ll have to create an image mosaic on top of the dt1 files.
See the reference documentation and tutorials for details.

The GeoSolutions training also has a section showing how to set up a simple image mosaic using only the GUI.

Hope this helps

Thanks aaime, that was really helpful. I managed to make a working example just throwing into a ImageMosaic a directory with dt0 files.

But I am getting some issues. I am building a longitudinal profile in a desktop application. If I use directly DTED0 files from my hard drive the results is the upper image. Using WCS the result is the image at the bottom.

You can see the WCS result is like from a lower resolution. I tried to see what options I have into WCS query but I don’t see anything I can use. Can this be fixed?

Do you think it is ok to just use dted files into ImageMosaic or should I first transform it to Geotiff or something like that?

Thank you so much, you are awesome.
