I found Flavio's comment interesting that qix and MapInfo TAB used the same type of index. Much of my data is in MapInfo format, and I have always converted to shp for use in MapServer. I did two quick tests and found that the shp/qix is still faster than the MapInfo TAB. I assume this is due to additional overhead of the OGR driver. My tests were on a layer with ~13000 polygons. One test 'zoomed out', showing most of the layer, the other test 'zoomed in' to just a few polygons. Rich -- Richard Greenwood [EMAIL PROTECTED] www.greenwoodmap.com
