[postgis-users] Convex hull without overlapping geometries

[Roald de Wit]

Hi list,

To create a simple set of simplified polygons (states of Australia) to
use for spatial searches from a web client, i'd like to use the
convexhull function in such a way that the convexhull is not applied
where the boundaries would overlap with other polygons.
In short: where the state boundaries are on land: keep everything the
same, where the boundary hits the ocean: perform a convexhull.

Is that possible in PostGIS?

Regards, Roald
