Truncating names to suit the .dbf format would yield to identical names. This is how GDAL behaves: Attribute names can only be up to 10 characters long. Longer names will be silently truncated. This may result in non-unique column names, which will definitely cause problems later. Starting with version 1.7, the OGR Shapefile driver tries to generate unique field names. Successive duplicate field names, including those created by truncation to 10 characters, will be truncated to 8 characters and appended with a serial number from 1 to 99. For example: a → a, a → a_1, A → A_2; abcdefghijk → abcdefghij, abcdefghijkl → abcdefgh_1 Taken from http://gdal.org/ogr/drv_shapefile.html ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=679909&aid=3472020&group_id=118054 ------------------------------------------------------------------------------ Write once.
