Award Details: New York State Office of Information Technology Services received a $795,000 cooperative agreement from the U.S. Geological Survey (USGS) under the National Geospatial Program: Building The National Map (CFDA 15.817), effective September 15, 2025, through August 31, 2028.

Products and Services: The awardee will collect and deliver Light Detection and Ranging (LiDAR) elevation data and derived geospatial products across the New York City Department of Environmental Protection watersheds, covering approximately 3,569 square miles across Catskill, Delaware, and Croton watershed areas in eleven New York counties. Deliverables include bare earth Digital Elevation Models (DEMs) at 1-meter resolution in GeoTIFF format, hydro-flattened elevation data, hydrographic breaklines, classified point cloud datasets, and comprehensive metadata, all meeting Quality Level 2 minimum specifications. The awardee's responsibilities encompass airborne LiDAR collection, ground control surveys, point cloud classification, accuracy verification, and quality assurance review, while the New York State agency provides project oversight including flight plan and survey plan review, data validation, horizontal and vertical accuracy assessment, and final submission to USGS for review. This initiative advances the National Map's objective of providing high-quality topographic and hydrographic data for federal, state, and local government agencies, as well as the general public.

NY city department of environmental protection watershed period of performance: 09 15 2025 - 08 31 2028ABSTRACT summary: this project continues new york state s efforts to update statewide elevation data via light detection and ranging (lidar) collection in coordination with federal efforts. The project will cover the entire new york city department of environmental conservation (nycdep) watersheds (catskill delaware watersheds (AKA west of hudson) and croton watershed (AKA east of hudson)). The area of interest (AIO) was built out to avoid data gaps with existing projects. These watersheds cover portions of bronx, delaware, dutchess, greene, new york, orange, putnam, schoharie, sullivan, ulster, and westchester counties. All new collections will meet at a minimum quality level 2 specifications. Several collections cover the AOI including data from 2014 (79 sqmi), 2019 (2,404 sqmi), and 2022 (1086 sqmi). The proposed extents have significant overlap with existing data to provide sufficient data for checking and adjusting spatial alignment.
