Hello, I have a linestring shapefile with an elevation attribute. Is there a way using ogr2ogr (or some other command line tool) to write out a linestring3d shapefile which transfers the values of that attribute to the z value of each point in the line? Bryan ___

Hello, I'm using BuildPolygonFromEdges in ogr in an attempt to take some lines and convert them to polygons. For a number of my sets of lines BuildPolygonFromEdges fails. I think this is because the lines aren't closed. Is there a way to put a tolerance into BuildPolygonFromEdges so that nodes

kss, That's in the gdal-dev branch (I don't really know my way around the doe repository). I use both Windows and Linux, and as I recall, it was easier for me to get it running in Windows using the OSGeo4W installer then to rebuild on Linux. I know that's not much info, but maybe it's helpful.

[gdal-dev] gdal_fillnodata does not write out nodata value to metadata

When I run gdal_fillnodata, it fills some of my nodata spaces and doesn't fill others because I specify -md. However, the output file doesn't have the nodata value written out in the metadata. Is this the expected behaviour? See more details below. Bryan >gdalinfo -mm dem_nd.tif Driver: GTiff/
