ossim-mosaic does not recognize projections

[iskandervito]

Dear
I wanted to mosaic two images having ossimPolarStereographic projection.
I just checked that the projection is well set in the geotiff file by running gdalinfo on the two images (here is one of the output of gdalinfo
gdalinfo PROBAV_L1B-CALIBRATION_20171024_235442_2_V101_BLUE_QLK.tif gives this output

When I run the ossim-mosaic using the attached kwl file
I got this error
unable to create product projection

I attached the two images and the kwl configuration file
ossim-issue.zip

Hello: We had a little bug on the latest git repo. I’ll check that in soon. There was a core dump with that type of strip with single band sample that you supplied. Once I fixed the core dump of the latest code I was able to successfully mosaic the images.. I then tested the following command: ossim-chipper —op ortho *.tif out.tif The ossim-chipper application will do a full image mosaic. Other examples can be: ossim-chipper --combiner-type ossimImageMosaic --op ortho f1.tif f2.tif f3.tif outputs/mosaic.tif ossim-chipper --combiner-type ossimFeatherMosaic --op ortho f1.tif f2.tif f3.tif outputs/feather.tif ossim-chipper --combiner-type ossimMosaic --op ortho f1.tif f2.tif f3.tif outputs/feather.tif You also need to make sure that eh ossim-preferences file is set and pointed to by OSSIM_PREFS_FILE. There is a template that can be found under the git repo ossim under the directory share/ossim/templates/ossim_preferences_template. You need to make sure that the projection codes are pointed to by that file. Here is my example of those keywords: epsg_database_file1: $(OSSIM_DEV_HOME)/ossim/share/ossim/projection/ossim_epsg_projections-v7_4.csv epsg_database_file2: $(OSSIM_DEV_HOME)/ossim/share/ossim/projection/ossim_harn_state_plane_epsg.csv epsg_database_file3: $(OSSIM_DEV_HOME)/ossim/share/ossim/projection/ossim_state_plane_spcs.csv epsg_database_file4: $(OSSIM_DEV_HOME)/ossim/share/ossim/projection/ossim_harn_state_plane_esri.csv wkt_database_file: $(OSSIM_DEV_HOME)/ossim/share/ossim/projection/ossim_wkt_pcs.csv Take care Garrett Potts

Has this issue been solved? I encountered this issue too when I tried to perform mosaic on two images with "WGS 84 / UTM zone 46N". My images have only one band.

Hello! I had solved my problem.
1.make install
2.export OSSIM_PREFS_FILE={your install directory}/share/ossim/ossim-preferences-template
3.export OSSIM_INSTALL_PREFIX={your install directory}
