[postgis-users] Amoeba Hulls

[William Andersen]

Hi,

I'm fairly new to postgis, and working to automate a number of processes.

We are trying to compute market area polygons that look like the
attached image. These were created by some older software.

They are referred to as Amoeba Hulls, and they contain 80% of a
store's customers. However I can't find any solid documentation that
would allow me to reproduce them.

Does anyone have any ideas how these shapes are created or an
alternate name that I might be able to google? Additionally, we may be
in a position to finance the development of this feature.

regards,
Will
