\f0\fs28 \cf0 I\'92m going to start by looking at the very basics of editing. For people
that start editing I usually tell them to open one tab for the Map Features guide, and
another for editing OpenStreetMap. If you want to sign up for OpenStreetMap and get
yourself an ID \'96 it\'92s all free and you just need an email address and you can sign
up for free then you can start editing.\ So when I am logged in I can move ways, I
can start editing by clicking on the Edit tab.\
You can see we are tracing from Bing aerial imaging \'96 they have given us access to
use this. So this lets us add areas around buildings. The next time I save this then
I can also add additional data \'96 like an icon for a supermarket, a shop, a school,
etc\'85 This particular editor has been made really nice and easy.\
I can change the background. For instance there is some open Ordnance Survey data that
we can use \'96 it\'92s great for streams but we can also see where
some of the buildings and\ I can also switch on the GPS layer \'96 this
shows where someone has driven/cycled/walked around with GPS to form a track. And that
helps us line up and make corrections to ways, etc. I can walk you through\
If I do edit something it will start appearing on the map. Often it happens in 5 minutes,
it will always be there by the end of the day \'96 they are rendering the whole of the
world though so it can take a few hours.\ Trying to sell the concept of OpenStreetMap
in Scotland can be really challenging as there are already really good quality maps out there.
But if we look at Nairobi there is an area called Kibera which was one of the most impoverished
slums and there was no mapping or information on this area. Volunteers from OpenStreetMap
have started a project to map the area with handheld GPS and
mapping the streets, the water supplies, healthcare, etc. We also have a project to map a major
slum in Dar es Salaam that is currently ongoing.\
If we look at Dadaab in Kenya with 300,000 refugees there is almost no mapping. We have a simple outline and we have some
aerial footage from the UN that we can trace from. It has been there 20 years but there
is no existant mapping and that\'92s very embarrassing. But we are getting data in from
the UN and that\'92s not something we can do with Potlatch (the web editor for OSM).
Instead we will use JOSM. You can download an area, a city, a country and, if you really
needed it, the whole world (a hefty 10Gb compressed file).\
People get introduced to OpenStreetMap via Potlatch but they often move on to JOSM (Java
OpenStreetMap Editor). You can start renaming data en mass, you can search data and you
have some other powerful tools to play with. You can make quick easier edits to areas,
you
can add tags, etc. We can also view imagery in the background, look at the OpenStreetMap
view of the map. We used to have Yahoo! imagery but it has now gone from the net \'96 the Yahoo!
maps never caught up with MapQuest or Google Maps so it\'92s not there anymore. For most
places those Bing images are better and more up to date.}
