  • Ticket #5716

    • Property Version unspecified → svn-trunk
    • Property Summary faster gdal_rasterize for a large number of small geometries → [PATCH] faster gdal_rasterize for a large number of small geometries

  • Ticket #5716 – Description

    initial v3  
    44The old algorithm can theoretically still be more efficient for very large geometries (to be checked).
    55
    6 The attached files are working on 1.11.1. Two options are added to the command gdal_rasterize: the first one is -cumul which make use of an hidden option of gdalrasterize alogirithm. the second one is a switch between the old alg and the new one.
     6The attached files are working on svn-trunk rev 33442.
     7
     8The default behaviour is to use the original algorithm when nb features < 1000, then use the new one. The algorithm can be explicitly set with the '-optim' param.
