does the size of the dbf file influence the size of the spatial index (qix)?

[Bart van den Eijnden]

Hi list,

normally my spatial indexes are small compared to the size of my shapefiles..

Now I have the following situation:

04-07-2005  16:46          163.888.026 acn.dbf
04-07-2005  16:46           39.730.468 acn.shp
04-07-2005  16:46            4.966.396 acn.shx
22-07-2005  16:21          119.741.008 acn.qix

So the spatial index is 119 Mb, while the shapefile is only 39 Mb.

For another shapefile I have the same type of situation:

28-02-2005  10:58           22.805.942 hnrtekst_text.dbf
28-02-2005  10:58            1.793.808 hnrtekst_text.shp
28-02-2005  10:58              512.588 hnrtekst_text.shx
22-07-2005  16:24            6.434.784 hnrtekst_text.qix

Does the dbf size influence the size of the spatial index? I can't make any sense out of that, but maybe somebody can ... ?

Best regards,
Bart
