OGR uses the AVCE00 library to provide coverage access, but the version shipped with GDAL 1.5.0 is 1.2.2, which has limited capability to access the non-geometry tables. AVCE00 version 2.0 was released in August 2006 and provides significantly enhanced capabilities for working with the associated coverage tables, including (for Network coverages) .NAT, .SEC, .RAT and .TRN. As ESRI still use this format for Network datasets, would it please be possible to enhance OGR to use the later version of AVCE00 and provide layer access to the NAT, etc., where these exist in a line covarage? Many thanks." enhancement closed normal OGR_SF 1.5.0 normal wontfix AVCBin Daniel Morissette warmerdam
