[Geoserver-users] Process orthophotos to plugins mosaics

Hello!

At first, sorry my poor English.

My mother language is Spanish.

I want share, via webbroser, a recents orthophotos take on the air.

I read in others formuns that, the ortophotos required a pre-process
to make a mosaic, to resolved "errors".

I find "er mapper" software to do this, but always I tray to use
opensorce software.

I want know if exists any opensource solutions to pre-process the
orthophotos and make the mosaic.

In additions, I have georeferencing in shape file of the orthophotos.

But I think that, I can't use this shape file to implements my mosaic
in geoserver because, each orthophoto have a diferent resolution.

The orthophoto format is ".PMI" but I think that this format is JPG
with PMI extensions.

In any case I can export .PMI files to .JPG

thanks for all!

Hi,

I would have a try with OSSIM Image linker (http://ossim.org). There is a illustrated tutorion on the web site and Image linker is not very hard to learn.

Manolo,
If every orthophoto has a different resolution, (pixel size different in x,y) there are two ways to do this:

  1. A different layer for each ortho, let GeoServer resolve the differences. Not too speedy, but might work if you have only a few.

  2. Use Gdal to convert all the orthos into a common format/resolution/projection, then use the Mosaicing plugin in GDAL to display them. Jpeg2k might be a likely suspect for the format, although I don’t know.

For either, you can then use the GeoWebCache to speed up the access by the end user. However, I haven’t been able to get GeoWebCache to work (yet!), so this may be wishful thinking.
