[postgis-users] Who is Using PostGIS? For What?

[Stephen Davies]

Who are you?

Stephen Davies Consulting - information management consulting.

What are you using PostGIS for?

Primary PostGIS application is the management of soil quality (moisture, 
salinity etc) and weather data collection and analysis.
Cadastral, irrigation unit and logger/probe data is stored in a PostGIS 
database and associated metric data automatically uploaded for storage 
and analysis.
Analysis results are fed back to farmers etc via Grace plots and/or 
colour-coded Mapserver web pages and pages specially formatted for 
reception by 3G mobile phones (so that farmers out in the paddocks can 
review status in (almost) real time.)
The "standard" Mapserver pages are also queryable to display 
metrics/analyses for selected locations.

The application also uses SMS messaging to turn water pumps on/off based 
on the metric analyses.

Why did you choose PostGIS?

I am a long-term PostgreSQL user so PostGIS was an obvious first choice. 
Nothing I have seen since has cast any shadow on that decision.

What makes you happy about your PostGIS installation?

All of the GIS functions and capabilities that I need are there and 
perform well.

What makes you unhappy about your PostGIS installation?

I am still not confident that I know how to best handle data from 
multiple zones/SRIDs given the single-SRID/table constraint of PostGIS.
