I am mapping the area to the west of Springfield, Massachusetts and the area to the north and east of Hartford, Connecticut.
I have found that the imported data for Massachusetts is pretty accurate regarding the location of streets. However, it is not completely up-to-date and does not include many non-street objects such as railways, lakes and rivers.
The street data for Connecticut imported from TIGER is badly out-of-date and indicates their positions only approximately. I am using a few GPS traces to align the Yahoo aerial photographs and then using the photographs to adjust the street positions.
H & H Canal
I am attempting to locate and map the remains of the Hampshire and Hampden Canal which once ran from Southwick, Mass. to North Hampden Mass. There is an article about the canal in the Valley Advocate.
Here are some notes on using and contributing to OSM. WHen I get a clearer picture of some of these issues, I may push some of this information into the relevant wiki pages.

There are three major editors for OSM. They are:
- Potlatch: runs in browser, requires flash
- JOSM: runs in JVM, more features than others, interface uses a lot of shift modifiers and other things that are not obvious
- Merkaartor -- not as capable as JOSM, but much easier to figure out
There are also a number of special-purpose editors:
Web Slippy Maps
- The front page of openstreetmap.org has a slippy map.
- Informationfreeway.org slippy map has numerous layers (as of May 2012 all of the layers seem the same)
- Cloudmade provides a slippy map API and OSM tiles in various styles.
- OSM_Inspector is a series of slippy maps which highlight possible errors in the OSM data.
- Keepright is another slippy map which highlights possible errors.
- Openstreetbugs looks like a place to report what one can't fix

Creating Paper Maps
These programs and websites may prove useful for creating paper maps.
- gpx2png.pl is Perl script which downloads tiles from OSM tile servers, stitches them together, draws GPX traces and waypoints on them, and creates a PNG image.
- Reportlab Toolkit is a Python library for producing PDF files. It is easy to use. I find it useful for turning map images created using Thomas Fischer's script into proper atlas pages.
-  The Walking Papers project] provides a way to print paper maps. It is intended that one then mark up these maps, scan them, and send them back for data entry.
- maposmatic.org is a web service for printing city maps
- Proposed_features/House_numbers/Karlsruhe_Schema Schema proposal, includes link to address geocoding implementation
- Key:addr -- As approved
- The Cloudmade web service API includes an address geocoder
- File formats:
- Law defining state border
- MassGIS website
- List of town GIS websites
- OSM MassGIS page
- Layers we might want to import:
- TopOSM -- Shaded relief maps from MassGIS and OSM
