Maps are a form of power whose use
has traditionally been limited to the State.
There are tons of options available...
A free, open source, volunteer-generated map of the world that is editable by anyone, anywhere with a computer and a connection to the internet.
Data added to OpenStreetMap has the potential
to get used by a lot of people all over the world.

We're going to do a little armchair mapping.
Don't worry, this has nothing to do with armchairs...
Armchair mapping just means tracing items onto the map from aerial imagery without going out to ground-truth them.
Open the map: OpenStreetMap.org
Choose iD Editor from the Edit menu
From the Help menu on the right,
select Start the Walkthrough
The walkthrough will show you all the basic information you need to be able to use iD editor.
There are essentially 3 things you can add to the map:
Points are used to add things like
businesses, bus stops, murals.
Things that you could stick a pin
into the map and say "It's here!"
Lines are used for roads and trails.
Areas (polygons) are used for
building footprints, parks, lakes, etc.
Things that better described by their outline
rather than a single point.
