Every five years, the State of New Jersey contracts out a statewide aerial photograph. From the 2007 aerial photography, a highly detailed land use/land cover data set was created. Now that the 2012 aerial photography has been released, we would like your help in identifying new urban development visible on the 2012 aerial photos.
Starting at 12 noon on Tuesday October 8th, the number of development units identified will be tracked for each participant. The most productive users will be listed on the status page. Claim bragging rights for being a top contributor!
Zoom into an area and search the aerial photograph for visible development. Areas known to have been developed before March 2007 have been masked out in black. Once you find new a new house or structure, select the type of structure on the Add Points panel and then click on the center of the structure to record the new development.
