[postgis-users] overlapping geometries

[volker.emmel at lwk-rlp.de]

hey list,

i have the following problem:

- i have overlapping geometries in one layer in my postgis (8.3) database.

-> how could i find the overlapping geometries??

->i could not divide into two layers...
-> if i have two layers i could use st_contain, but in one ??

- it will be over 6 million geometries....

any idea?

thanks
vollbtz
