OSM Dos and Don'ts

Must: Provide attribution if you display OSM data

"© OpenStreetMap Contributors" and
link to license openstreetmap.org/copyright

Don't: Copy data from other maps (Google, Bing, etc.)

Do: Read Good Practice

Don't: Delete a bunch of data unless it's incorrect. Contact the original contributor.

Do: Ask questions. OSM mailing lists Don't: Guess.

Be Careful: "Mixing" OSM with other datasets. Read ODbL. Could trigger sharealike. Generally, displaying things on top of OSM is okay.

Do: Watch your changes go live on openstreetmap.org. Takes a few minutes.

Must: Have fun!!!
