OPM: 2016 Statewide Flight


Acquisition of Statewide High-resolution Aerial Imagery and Elevation Data Scheduled for Spring 2016



Overview

The State of Connecticut and its nine Regional Councils of Governments are collaborating to achieve statewide coverage of unprecedented, high-quality geographic information system (GIS) mapping data of benefit to all people who live, work, and learn in Connecticut.

In September 2015, the Office of Policy and Management awarded a grant to the Capitol Region Council of Governments, who will administer the project on behalf of all nine Councils of Governments.  The grant award is funded through the Regional Performance Incentive Program, with additional contributions from the Departments of Transportation and Emergency Services and Public Protection.

Data Products

This initiative includes acquisition of the following GIS services and products:
  • Statewide aerial photographs and orthoimagery of 3-inch pixel resolution.  The orthoimagery will meet the ASPRS Class 1 standard.
  • Statewide elevation data and topographic products derived from "LiDAR."  The LiDAR will meet USGS Quality Level 2 vertical and horizontal accuracy specifications.  LiDAR-derived products will include:
    • 1-foot and 5-foot contour lines
    • Bare-Earth Digital Elevation Model (DEM) using 1-meter pixels in GeoTiff and MrSID formats
    • LAS dataset adhering to the USGS LiDAR base specification

Municipalities, state agencies, utility companies, and other interested parties have the option to complement the above base products with additional buy-ups, such as:
  • True orthoimagery
  • Planimetric data such as building footprints, edge of pavement, road markings, vegetation, etc.
  • Custom geographic boundaries of the base products
  • Additional LiDAR classifications and products
  • Hydro-enforced / hydro-conditioned DEM
  • Impervious surface data
  • Contour annotation
