At SotM conference, I demonstrated what appears to be a new type of mapping
website:
http://almien.co.uk/Sketch/
It allows you to get a map of any location as a static image hosted on my
server (from the tiles at home layer, at the moment)
You can then draw on the map (directly, on the website) using the
"finger-painting" tool. That's kind of like the "shared whiteboard" idea,
and if multiple people are drawing on the same map simultaneously they'll see
each others' changes (hit refresh to reveal them).
(Currently you all need to be logged in as the same account to share a drawing
space)
This allows you to do several neat things:
(*) Give directions to your business, home, or event. Don't settle for just a
push-pin, but actually sketch the good and bad routes onto the map, add notes
about public transport, photos of road signs, or anything else
(*) Create specialised maps. Make a canal map by blanking-out any roads that
aren't relevant, and add POI labels or photos instead.
(*) Plan your mapping party. Sketch the "cake" regions onto the map
(*) Improve the map. Ships and dragons in the blank area. Illustrated maps
using real data underneath.
(*) Let your friends tell you about errors in the OSM map. They can circle
the error and write notes on it, without having to know any JOSM
(*) uhh, entertain your kids with it. They seem fascinated by this drawing
idea.
The best bit is that the overlay is stored separately to the original map. So
when the roads in your area get updated, the map underneath your sketch
changes.
You're not limited to just the finger-painting, you can make changes in your
favourite graphics program. Use white to fill on any areas that you want to
be transparent and show the map underneath.
(that's even easier if your graphics program supports layers, but it's easy
enough to do in paintbrush or whatever. I even managed to get inkscape to
produce a decent overlay image, from a vector drawing)
This is still in development, so treat it gently, and please don't create an
infinte number of images until I've had a chance to add limits ;)
