Things to do

Routes and Relations

Work is underway to create relations for the roadways, transit systems, bicycle paths and railroads (both freight and passenger) throughout the state. The /Railroads wiki has not yet begun, but it is in an early planning phase. (abandoned?)





The TIGER import is finished, however there's still significant amount of cleanup left to be done. Review roads, realigning them and updating attributes as needed. Many track roads are incorrectly tagged with highway=residential, especially in the Pinelands, rural areas, and military bases. Replace with highway=track, and it's beneficial to add the tracktype=* too.

Junction and connectivity problems have mostly been fixed over the years.


Note that, unless stated below, tags should not be applied simply based on the administrative level of the road.

  • Motorway Controlled access throughout; divided highway; no traffic lights or cross traffic, save for frontage roads. Should include all toll roads.
  • Trunk Generally controlled access (interchanges, flyovers, and jughandles), sometimes using traffic circles (e.g. NJ 38, NJ 70, NJ 23, NJ 208). Can be applied to a long two-lane route for at least 30 miles as long as it does not parallel a road built to higher standards (e.g. NJ 49, NJ 31, US 40, US 322, US 206). Freeway-grade portions may be designated as motorways if they meet all requirements.
  • Primary Well-traveled roads that run long distances through an urban area or between areas where a trunk road or motorway is not available. May parallel a motorway, but not a trunk road (e.g. US 9 south of Toms River, US 202 in Morris, Passaic, and Bergen Counties). Should include most 500-series county routes and select 600-series roads.
  • Secondary State, county, and municipal routes that serve as arterials or carry long distances, or form links between major roads.
  • Tertiary All other signed numbered roads and important municipal roads, but not any roads maintained by a homeowner's association, public institution, or business.
  • Residential All other complete public access roads.
  • Unclassified All public access road stubs and high-traffic roads maintained by a homeowner's association, public institution, or business.

Protected lands and state parks

The Protected Areas Database of the U.S. from the USGS provides protected area boundaries for the entire United States, but it can be downloaded as shapefiles by state. Click to download the NJ PAD-US data (warning, about 200 MB, but this is because the ZIP contains a few shapefiles.) The only one you need is "PADUS2_0Combined_DOD_Fee_Designation_Easement_NJ." The boundaries are often divided by roads. These should be removed as they just needlessly complicate the map. Also, consider removing very small exclaves and inner boundaries, especially if they are not verifiable on the ground.

New Jersey Aerial Photography

Comparison between Potlatch and JOSM using the 2007 NJ aerials WMS. Click on the image for full size.

The State of New Jersey has statewide aerial photography available through a Web Map Service. There are no restrictions on its use. The most recent data available are from 2015. Even though this data covers the entire state with little temporal variation, aerial photography provided elsewhere is more up-to-date, so it should be used with caution.
