# Editing OpenStreetMap with your own aerial maps

It's easy to add your MapKnitter exported map as a background layer when editing OpenStreetMap. This wiki page explains how to connect to Potlatch 2 and iD editor. This slide show from State of the Map US 2013 may help illustrates these workflows: http://www.slideshare.net/LizBarry/2013-0609-sotmussf There is also a case study of an earlier method at the bottom of this wiki page.

### Potlatch 2

With help from Andreas Trawoeger from the OSM-talk list, we set up a "deep link" underneath the Export formats area, so you can open your map directly in OpenStreetMap's Potlatch 2 editor by clicking "Use your map to contribute to OpenStreetMap in Potlatch":

Note: this is only available for maps which have been released under open licenses, such as CC-BY or public domain.

### iD Editor

In Mapknitter.org, there is a "deep link" underneath the Export formats area so you can click "Use your map to contribute to OpenStreetMap in iD". This will open the iD editor hosted on openstreetmap.us.

Manual method for adding a TMS layer on openstreetmap.org: you can click the Edit tab, choose the iD editor, then click the background tab to add a custom layer. The URL you paste in will be formatted like this: https://mapknitter.org/tms/2011-7-31-brooklyn-gowanus-vis/alt/{z}/{x}/{y}.png

### Old technique (no longer necessary)

In this example I'm using a map of Mestia, a city in the Svaneti region of Georgia.
