Managed marked-up tile set #12

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
When traveling, it would be nice to be able to see all of my previous
tracks on the map, either to find my way back somewhere I have been before
or to make it easier to tell that I am choosing a new route I can verify is
correct in OpenStreetMap.

It is too slow to have hundreds of GPX files that are all redrawn each time
the map is refreshed.

There is some code already in the application to choose to display a
modified version of tiles, but no code yet to save such modified tiles.

A flexible way of doing this would be to keep a separate set of 
mostly-transparent
tiles (like Maplint tiles) which only contain rendered tracks. These could be
overlaid on any other tiles. Experimentation will be needed to see whether 
updating
all the zoom levels in real time is feasible. Updating only after a track is 
finished
or on the desktop could also work. Pre-rendering does mean that changing 
rendering
rules would require redrawing. Perhaps some clever palette swapping could help.
