Sanborn was engaged to acquire, process and deliver a 3-Dimensional Lidar point cloud dataset critical to a New York City Program designed to improve the environment, build the economy, and enhance the quality of life for all New Yorkers. ‘PlaNYC’—is under way with the long-term goal of cutting greenhouse gas emissions by 30% by the year 2030. An important facet of this goal includes a critical solar energy program geared toward the development of cleaner, more reliable and renewable energy sources. The Solar Energy initiative is being championed by The City University of New York and the implementation and analysis is being managed at the Center for Advanced Research of Spatial Information (CARSI) at Hunter College, New York.
The project coverage and Lidar density demanded 440 flight lines, over 15 billion points and close to 1 TB of data. Two Aircraft and two Leica ALS 50 II Lidar sensors were utilized to complete the acquisition over a two week time period.
CUNY is using the final 3D-building model to calculate the intensity of Insolation for every building throughout NYC. The information will be used to calculate the return of investment for homeowners who install solar panels on their rooftops. Con Edison also was involved in the program and provided solar panel calibration information for making ROI calculations more accurate. The data is available through an interactive website for all NYC residents to evaluate the cost savings for solar installation on their homes, and contribute to the strategic goal of making NYC greener. In addition to being utilized for Solar Energy initiative applications, the data will be shared with other City agencies and utilized for any variety of additional GIS applications.
