comment How to Create database using OGC compliant geometries and Custom type Geometries?
From the title, I think he's asking about geometries which can be drawn on the screen and edited by the user at runtime and later stored as a layer of dynamic geometries, in a postgis database when the application's workspace is saved. Something like this would typically require control points and handles to be stored with the geometry, which isn't (as per my knowledge) supported directly by OGC. (at least I'd like to know) How would such dynamic data be stored in a database?

comment Most optimal algorithm for contour correctness?
Thanks. I've been trying to find out which algorithm GDAL uses for creating contours, but couldn't find any hint on that. Anyone here know? Basically my main requirement is that I should be able to use GDAL (or any other contour generation algo) to create reliable contours which are the best in terms of accuracy (when compared with any application that displays contours). I don't want to start using GDAL and then much later realize that it doesn't suit my needs of multicore support, accuracy, smoothening or specifying the height interval between major and minor contours.

comment Most optimal algorithm for contour correctness?
I agree. Good advice. But assuming the data constant, which would be the best algorithm/library, is what I'm asking?

comment What's an efficient way of detecting road junctions on a map?
Just sharing: Another database I've come across is this - <oracle.com/technetwork/database/berkeleydb/overview/…;. Apparently the queries are very fast because the queries are available as libraries which can be embedded in the application.
