comment How did OpenLayers 3 managed to export map from other domain?
There has to be more to it. All my server responses (map tiles and static files) have this header set, but the canvas is still tainted.

comment How can I get the values returned by an OpenLayers bounds object in Longitude / Latitude format?
Handler.Box actually returns a Bounds geometry with pixel coordinates, not projection coordinates.

comment Libraries and/or ideas for navigating WMS time-parameter
How much screen estate do you want to use for the control? Sliders work if you have a lot of room (otherwise you will have problems with fine-grained control), calendars/spinners provide better control with less space, at the cost of speed of use. I believe there should be a lot of prior art in UI design for time/date selectors.

comment Creating nanoscale DEM with GDAL
In a non-projected file, you would convert from pixels to distances via the dpi setting ("dots per inch"). If you have a task where GIS tools work better than CAD/analysis tools, I think you could always use the actual dpi value (which should be pretty high) and units of distance in any projection to make the distortion neglectably small.

comment uncaught typeerror: undefined is not a function
Make sure your copy of OpenLayers has WMSGetFeatureInfo built-in. OpenLayers is a modular system, and not all the possible features are activated by default in every version/distribution.

comment Is there a way to identify and remove similar GPS tracks in PostGIS or ArcGIS?
That should work a lot faster indeed.

You can still compare the tracks segment by segment, increasing the index on track A until it passes the current index on track B, then increasing the index on B and repeat.

I can confirm BradHards - the spatialite extensions in the sqlite driver are optional.

comment How do you treat partial 3d features in PostGIS?
A 0 z coordinate is not correct, and does not represent the same value as the data source. ST_Force_3D will not work for us. The idea is to be able to have a correct bidirectional mapping between the data source and our database.
