not exactly. My problem is about behaviour of human. When some person use a GIS application, do behavour of person have laws. and when their operation in GIS application is mapped to spatial computing :interset , contains , distance, ...defined by OpenGIS, Do same computing operation on same spatial object is performed regularly, and then I can cache the result of these computing operations.

<br><br><br> hi,everybody!<br> I was thinking a problem: Is there a rule: the same spatial<br>functions using the same spatial objects are performed regulaly, at least<br>queries from people living same area will resulted in such
<a href="http://scenes.eg">scenes.eg</a><br><<a href="http://scenes.eg/">http://scenes.eg/</a>> . people in New York will often query area size of<br>someting in New York, and They are also more interesting in postion
<br>relationship of buidings in NewYork. I think this conforms to rule of thumb.<br>But now I hope to approve it with facts. Do you have ever think about this<br>quesiton and have some statistics on such problem. Can you give me some GIS
<br>trace and I use it to confirm it.<br><br><br> bless you!<br><br><br>_______________________________________________<br>postgis-devel mailing list<br><a href="mailto:postgis-devel@postgis.refractions.net">postgis-devel@postgis.refractions.net
