Hi, I have been trying to get create a DEM based on a contour shapefile as outlined in Victor's video.
http://www.youtube.com/watch?v=T0-_ny4Cj9U Initially the process baulked because the contour data was in 3D and Sextante did not process the file correctly. I eventually converted the file to 2D using ogr2ogr then tried again. No luck, the process appeared to finish but the image file did not appear in any directory. I have tested the process on old data that this process worked on previously but it now does not work. After looking at all the usual suspects I decided to upgrade to the latest versions of gvSIG and gvSIG-CE to see if this process could be completed and if not whether any feedback was given by the program as to why not. ***** DOWNLOADS *********** gvsig-ce-1.0.svn-linux.zip 210.17MB gvSIG-1_11-1305-final-lin-i586-withjre-j1_5.bin 193.54MB ***** INSTALLATION *********** gvSIG 1.11 -- Quick and easy, although would confuse a newbie (e.g. change execution flag). gvSIG-CE -- unzip and you are done. ***** OPEN PROJECT *********** gvSIG 1.11 -- Warned me that the project file, if changed would not be able to read by older version of the program. gvSIG-CE -- Slightly quicker to open. Same warning about the project file. ***** OPEN PROJECT *********** gvSIG 1.11 -- Baulked. Generated the error stating the raster file could not be created -- the same as gvSIG 1.10. No error message was in the main console. The message was "es.unex.sextante.exceptions.GeoAlgorithmExecutionException: Error exporting the generated raster to the file: ..." gvSIG-CE -- Worked first pop. Created a raster as expected. All packages use the same Java 1.6.0_20. I suspect after snooping around that the version of sextante is newer but it does not explain why a program that used its own java and libraries would or could change (both the current version and the latest download of gvSIG 1.11). I have made the DEM using this process several times using version 1.10. Obviously these packages are not autonomous from the system. For the record. I am using gvSIG 1.11, Ubuntu with the xfce desktop and the above mentioned java. I suppose there is something to be said for having all the usual tools in the same toolbox and already interconnected. -- Cheers Simon Simon Cropper - Open Content Creator / Website Administrator Free and Open Source Software Workflow Guides ------------------------------------------------------------ Introduction http://www.fossworkflowguides.com GIS Packages http://www.fossworkflowguides.com/gis bash / Python http://www.fossworkflowguides.com/scripting ------------------------------------------------------------------------------ This SF email is sponsosred by: Try Windows Azure free for 90 days Click Here http://p.sf.net/sfu/sfd2d-msazure _______________________________________________ Gvsigce-community mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/gvsigce-community
