[mapserver-users] shptree e sortshp

[Tyler Mitchell]

Did you see the page: http://mapserver.gis.umn.edu/cgi-bin/wiki.pl?ShpTree
Shptree creates an index for the .shp file, storing the info in the .qix
file.  Mapserver uses the .qix file as an index for the associated .shp
file when it loads data.

I´ve read the descriptions of the shptree ´n´ sortshp utils...at the utils
page from mapserver site.

but i din´t undestand what really does theses programs.

1.what is the real purpose of indexing a shape with sortshp? does the
program index also the .shp file ?

2.what is the purpose of the .qix file that is generated with the shptree
command? how this is file is read?
