Hi all I have an ESRI Personal GeoDatabase .mdb file (PGeo) which I would like to read and convert e.g. to Shapefile. The PGeo file contains "circular arc"s (or circular curve) and since OGR only supports linestrings they should be segmented (similar to http://www.gdal.org/ogr/drv_ili.html ).
Now it turned out that the output is wrong: It seems that at least the midpoint(s) are misinterepreted. In fact, when looking at the source (line 430 ff.) there's a TODO there: http://trac.osgeo.org/gdal/browser/trunk/gdal/ogr/ogrsf_frmts/pgeo/ogrpgeolayer.cpp ESRI user doc says at http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//002t0000000m000000.htm "Circular arc curves use a mathematical formula to draw the curve. If you export a geodatabase feature class containing circular arc curve features to a shapefile, the curved features are transformed to simple line features with closely spaced vertices to capture the curved shape". => Does anybody know this formula and/or the meaning of the additional attributes in the byte stream? Yours, S. _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
