GDAL Plugin

The GDAL Plugin provides access to all the raster and vector formats support by GDAL and OGR. You can find a complete list of raster and vector formats here:

• ​Raster Formats
• ​Vector Formats

Drivers

All GDAL/OGR drivers are prefixed with "gdal_". For example, the GDAL driver code for the ERDAS Imagine file format is "HFA". The equivalent driver in OSSIM is "gdal_HFA". Here's an example of how to use the HFA driver in orthoigen:

ossim-orthoigen -w gdal_HFA input.tif output.img

Note that there is some overlap between formats supported via GDAL and the other plugins (e.g. jpeg, png, nitf, tif, etc.). Let's take PNG as an example. The PNG Plugin uses ossim_png. GDAL's png driver is called gdal_PNG. In orthoigen you can specify which writer to use. Example:

ossim-orthoigen -w ossim_png input.tif output.png

ossim-orthoigen -w gdal_PNG input.tif output.png
