[OSM-talk] GPX tracing from New Popular Edition Maps

[Nick Burch]

Hi All

Having finally cracked those last pesky few IE issues, my GPX tracer is 
now ready for wider use:

 		http://gpx.npemap.org.uk/

The navigation is much like the main npemap site, until you're fully 
zoomed in. At this point, you click away to mark points, click on them 
to remove mistakes, and then generate a GPX file of your clicks.

As the scans aren't perfectly tiled, you'll need to calibrate before you 
generate the GPX. Click on the calibrate link, then click where the grid 
lines cross. Repeat until you've done all 4 joins, or as many as you can 
see (they can be hard to spot in dense urban areas)

Few things to be aware of:
* When you scroll around the map (nsew links), you'll loose your gpx
    points. Generate the GPX before moving off
* Calibration doesn't really work across sheet boundaries. Calibrate and
    trace up to one, then scroll over and calibrate+trace on the new sheet
* Some features have moved since the 50s. Please use local knowledge to
    that something's still there before tracing
