Lx-Viewer is an open source dxf/dwg viewer (Linux/Windows) which saves file to up to 2002 dwg/dxf version.The best way to import a DWG file in OpenJUMP is to export it in DXF format using external software. Nevertheless even importing a DWG drawing or more in a Java software could become a stressfull action since those libraries are still slow and need more developing strategy. Standard jython libraries for opening DWG are not used by OpenJUMP while available in other Java GIS software (Kosmo and GvSIG). You must use different procedure whether you want to import DWG or DXF in OpenJUMP. Symposium on use of Open Source Software in EU public administrations]. Import aereophotogrammetric topographic drawingsĪerophotogrammetric DWG drawings are still diffused by many public offices (for instance, in Italy) despite many Public Recomandation to use open public file format(see for EU [ ). Most of these cad drawings are not georeferenced. There are basically two situation which requires the usage of CAD drawings: 1) import in a project aereophotogrammetric drawing (already georeferenced) or 2) import in a project tecnical drawing produced by engeneers and architect or derived from vectorialized raster images. The aim of this tutorial is to help users who have to work with Autocad files in a GIS project using OpenJUMP. QCAD comunity edition represent a valid opensource alternative to Autocad for GIS needs. Autocad software still remains the best CAD drawing available, despite the cost and the limitation for public DWG format. Autocad format DWG and DXF represent an important standard in many technical public and private office.
