For the 2015 street tree census, the city decided that in the Age of Apps, it should be done in a digital friendly way, making it more efficient and reliable, yielding a “living data set” with more detailed and easily updatable information. So it used a fun mapping procedure, designed by local non-profit TreeKIT, that married new geospatial technology with old surveying tools. (Interestingly, not including GPS, which in a concrete canyon like NYC is accurate only to within 15 feet.) An algorithm was created so volunteers could use a wheel to measure distance between trees, enter numbers on a smart phone, and, presto, a “geometry constructor” would map the trees along the curb. The street tree census app also integrated online training and a platform for mapping social events to recruit and energize volunteers—2,241 eagerly signed up.
