I am trying to convert a SOSI file (Norwegian geodata format) to a shapefile. I have set up gdal, but apparantly there is a lot of things that I dont have support for. When I do a ./configure, this is the result:

  enable OGR building:       yes
  enable pthread support:    yes
  enable POSIX iconv support:yes
  hide internal symbols:     no

And doing the command results in this:

~/gdal$ ogr2ogr -f "ESRI Shapefile" /media//Geodata/testing/sosi.sos /Documents/test.shp FAILURE: Unable to open datasource `/Documents/test.shp' with the following drivers.

I am fairly inexperienced with this, so I am trying to learn. What is going on here, what am I doing wrong?

According to the manpage http://trac.osgeo.org/gdal/wiki/SOSI you have to compile the SOSI support yourself.

This is dependent on the operating system (which you have not mentioned) and documented on the page.

If you are on a mac, see also Converting SOSI to ESRI Shape

This page (also available in English) has a link to compiled binaries for Linux and Windows of gdal 1.7.2 at the bottom: http://labs.kartverket.no/sos/

For the Windows version, you might run into some error with libeay32.dll. Deleting the ssleay32.dll solves this problem. Or copy both from a 32-bit version from http://www.gisinternals.com/sdk

  • Thank you. I am using Linux. I have compiled the SOSI- support myself, but apparantly I need to add the -DSOSI_ENABLED option. However, I am unsure where to do that. It was at labs.kartverket.no/sos someone said this – DOMINUS MIHI ADIUTOR May 10 '14 at 13:39
  • Maybe a typo? Looking into the configure file github.com/kartverket/gdal/blob/trunk/gdal/configure, --with-sosi sets SOSI_ENABLED=YES. – AndreJ May 10 '14 at 14:05
  • Perhaps. Well, I did follow a guide, and did the with-sosi option. I can try again, maybe it didn't work. – DOMINUS MIHI ADIUTOR May 10 '14 at 14:29
  • Does you configure ouput SOSI support: yes. After when compiling, you can also try to do a make clean before to no keep "garbage" between compilation with different params due do configure changes. – ThomasG77 Nov 9 '14 at 17:02

One thing that tripped me up when reading SOSI files using GDAL: You need to make sure you have write access to the directories containing the SOSI files. The library creates a temp file in the same directory as the file you are reading from. This is explained in a NOTE on the page http://trac.osgeo.org/gdal/wiki/SOSI

Also, make sure the environment variable is set:
GDAL_DATA

I figured out what was wrong by setting these environment variables:
CPL_DEBUG=ON
CPL_LOG_ERRORS=ON
CPL_LOG=cpl.log
The cpl.log will contain useful error messages that can help you if you are still having problems.
