One early frustration with wanting to help the OpenStreetMap project was how do you edit the data easily?
OpenStreetMap has lot and lots of data already, though more and more people are required for thier local knowledge and to do the mamouth task of keeping the ‘map up-to-date’
Well there are lots of different applications from online editors to compiled source code are out there. Which is easiest and user friendly?
These two are mapperz best picks
Merkataartor (v0.14) – fairy new software – but nicely laid out user friendly. Has great potential and is supported by most OS
see the list
Small download, very simple to use – download by area/map of your choice.
No knowledge of OSM to start using. (But advise you to research first)
uploading does require a osm account so you can contribute but downloading and viewing data (in cartographic map-form) does not require a login.
Software is updated regularly and many features have been added – recently Area digitising and tagging tools have been introduced.
Map Style mode – set one from the list or make your own.
(requires an update to v0.14)
Potlatch – long standing Open Street Map ‘online editor’ but now more user friendly than ever (thankfully).
Back along mapperz liked the idea of editing in a browser (as all GIS will be in the future).
But Potlatch back then was slow,buggy and choked the browser up – all those issues are long gone and now it is a really fast and easy way to edit ‘live’.
Potlatch has greatly increased productivity due to the ‘drag and drop’ POI (Points of Interest) tool. Tip you reuse tag names with the ‘r’ button (repeat tag) remember to give as much infomation as you know.
Note: There are many tag names (too many to list) please visit

Yes, there are many, many other OSM editors out there but this is for the curious potential new user, that just wants to help out.
JOSM is currently the most popular desktop editor. It is a standalone Java application (requires Java 1.5) which allows fluid zooming, panning, and editing of a locally stored dataset, before uploading changes in a batch.
OSM2Go is a mobile mapping solution currently supporting the Nokia Internet Tablet family (N800 & N810), can also be compiled for the Linux/GTK+ desktop.
