comment How to make a square poly shapefile
Thanks, great answer, more firepower than I needed though. I'm sure another user will find it valuable, would make a great extension ; )

comment How to make a square poly shapefile
I did an hour or two of research, but time constraints meant I had less than a couple of hours to find the right tool as it needed to be discovered and installed and was not obvious from using help in QGIS. Anyhow there is a new answer so perhaps the collective state of GIS knowledge has advanced somewhat.

If you don't understand it does not follow that you then do. You either understand me or you don't.

I'm not sure you understood what I said. My answer is not related the the problem of projections but of planar geometry and running an algorithm therein. The rectification, if needed, was already assumed to have processed the data. So a problem of semantics at this point, no?

comment Resources to integration with external web service at desktop level
0down vote What do you have on your server, what do you propose for the client guest? Are you an intranet serving an extranet, a url serving the web? what are your parameters and services. Do you own commercial licenses for packages and as a hosting solution or desktop? and what are they? Are you developing on a localhost and pushing to a VPS or spooling it up on Amazon AWS? Are you using ARC servers or are you using postgresql? Is it a spatial development environment or a service only? Depending on what service you call it's trivial, all the rest is the harder bit.

comment How to query OSM for all beaches facing west? - QGIS preferred
run coastal query by countries and sub regions that have a west coast, only a problem if they have both coasts. Then look for angle closer to vertical intersection with equator and eliminate angles that displease you.
