[Mapserver-west] Crytozoology non-profit seeking advise

[Jason Birch]

I can't fault Paul for this recommendation, but I think that PostGIS
would be overkill for recording a bunch of points.  I'd probably go with
a text file (with appropriate mutex) or, if a restricting query by
attribute is required, SQLite or PostgreSQL.

More server-intensive applications such as PostGIS, MapServer, etc,
could be introduced if you had a more technical volunteer base and the
requirement for dynamic mapping and analysis.

I tend to lean with Mark, particularly if the number of observations is
relatively sparse at this point: use a mapping API like google maps to
start with, and do something  more custom only if you need to... the
architecture would be something like:

- Data form for collection which feeds into a
- PostGIS database which has a
- PHP/Whatever script to pull out points and return an XML document
- GoogleMaps API / javascript / dom to parse the XML and turn it into
placemarks

See: <http://www.refractions.net/white_papers/mashups/> for an example
of simple code for doing some of these things.
