[postgis] Next Level Redux

[Paul Ramsey]

Here is a graphic view of an OpenGIS "chain-of-being" using open-source
components. The missing bits of infrastructure are dotted lines. Note
that this is note the end-all and be-all of OpenGIS architectures: there
are lots of different ways to present a picture of OpenGIS. This is
arguably one of the less compelling ones. A more compelling picture has
independant organizations interoperating via an exposed layer of OpenGIS
services. So, I may use <Product X> for all my GIS work and data
storage, but organizations on the outside never see that, all they see
is my features exposed with a Web Feature Server, and my maps exposed
with a Web Map Server.

One of the reasons for using PostGIS/PostgreSQL for feature storage (on
of the future reasons) is that you need to support the OpenGIS
predicates and spatial operations in order to fully implement the WFS
spec. You also need transactional capabilities to support the updating
portion of the WFS spec.
