OpenStreetMap -
A Gentle Introduction
The plan:
- What is OSM?
- Why OSM?
- Howto
- Let's Edit
(Part 1/2) OpenStreetMap is a free geographic dataset of natural and
man-made features on the Earth's surface
(Part 2/2) OpenStreetMap can be edited by anyone! The dataset has been
built by millions of (mostly) volunteers.
Anything verifiable on the ground is okay in OSM
So what?
Trees? Who cares about trees?
Getting your hands on proprietary map data (like a road network) costs a lot
of money.
Map Pricing
OpenStreetMap is taking over!
In a few years, OSM will be the foundation of
- Mapping
- Navigation
- Real Estate
- Fleet Management
- Insurance
- Pretty much anything geospatial
Cool! How do I contribute?
Two main editors
- iD : Easier to get started
- JOSM : More advanced
Things to focus on today in iD:
- Add stores, cafes, etc. Click "Point"
- Trace buildings. Click "Area"
- Add roads. Click "Line"
- Add turn restrictions. Left pane
Must: Provide attribution if you display OSM data
Don't: Copy data from other maps (Google, Bing, etc.)
Don't: Delete a bunch of data unless it's incorrect. Contact the
original contributor.
Be Careful: "Mixing" OSM with other datasets. Read ODbL. Could trigger
sharealike. Generally, displaying things on top of OSM is okay.
