[mapserver-users] Topology error prevents rendering

[Rahkonen Jukka]

Hi,

OpenStreetMap data tend to contain topology errors and Mapserver sends an empty map when it finds an error on one layer of a multi-layer map.
Cases are like this:
msOGRFileNextShape(): OGR error. TopologyException: side location conflict at 1.48639e+006 6.89386e+006
[Tue Feb 14 09:41:37 2012].113000 msDrawMap(): Image handling error. Failed to draw layer named 'landuse_layer1'.

Topology errors would be best to correct in the data but I wonder if Mapserver could be somehow more robust and just skip the faulty feature or that certain layer instead of giving in totally. Sometimes it would be better to get an incomplete map than no map at all.
