New York City’s vital decennial tree census is undergoing a significant technological transformation, poised to leverage advanced systems to comprehensively assess the health and vitality of its expansive urban canopy, particularly targeting over 600,000 street trees.

Central to this innovative approach is the deployment of specialized vehicles equipped with ground-based Light Detection and Ranging (Lidar) scanners, a sophisticated remote sensing method that uses pulsed laser light to measure distances, creating precise three-dimensional models of objects and environments.

Officials recently announced that these Lidar-equipped cars are scheduled to commence their city-wide scanning operations across all five boroughs next spring, following preliminary preparations and the ongoing efforts of dedicated human volunteers in parks.

The data captured by these advanced scanners promises to offer unparalleled visual detail, generating 360-degree digital views of city streets that will bear a striking resemblance to the immersive experience provided by Google Street View, allowing residents to virtually explore their urban environment.

Beyond mere visualization, the true power of this initiative lies in the subsequent processing phase, where sophisticated artificial intelligence algorithms will meticulously analyze the collected Lidar data to compile extensive information on each tree’s exact size, specific species, precise location, and overall health status.

Crucially, this technological leap does not render traditional human efforts obsolete; the Parks Department has affirmed its continued reliance on dedicated volunteers for the meticulous tallying and assessment of trees located within the city’s numerous parks, ensuring a holistic approach to tree management.

These committed volunteers meticulously input detailed information about each tree into a specialized Parks Department database, a critical contribution that directly informs the agency’s strategic decisions regarding future tree planting initiatives and urban greening efforts.

Parks officials anticipate that the integration of this cutting-edge scanning technology will profoundly enhance the city’s capacity to monitor and improve the well-being of street trees, which are often subjected to harsher urban conditions and may be less frequently observed by traditional methods.

The comprehensive nature of this undertaking is underscored by plans to deploy these Lidar-equipped vehicles on virtually every single street throughout the sprawling metropolis, reflecting a city-wide commitment to fostering a healthier, more resilient urban forest for all New Yorkers.
