Abstract:
Orthoimagery in North Carolina captured during leaf-off conditions in early 2024, 6-inch ground resolution, is a public resource provided by North Carolina's Statewide Orthoimagery Program, supported by the NC 911 Board. The state program includes orthoimagery acquired between 2012 and 2024. The Program is consistent with the Business Plan for Orthoimagery in North Carolina (https://it.nc.gov/media/1955/download?attachment) that recommends acquisition of one-fourth of the state (or 27 counties) per year in a four-year cycle. The products are 4-band (RGB-IR) orthoimagery, 6-inch ground resolution in 5,000 by 5,000-foot tiles, in uncompressed and compressed formats, packaged by county for distribution and accessible through the NC OneMap Geospatial Portal. The project, Eastern Piedmont 2024 (CO24), was managed by the NC Center for Geographic Information and Analysis (CGIA) in the NC OneMap framework of data access. CGIA collaborated with the NC Geodetic Survey, the NC Department of Transportation's Photogrammetry Unit, and the Land Records Management office in the Office of the Secretary of State to form a state team with expertise and experience in orthoimagery. Acquisition contractors were selected by a Qualifications-Based Selection process. In addition, the Statewide Mapping Advisory Committee's Working Group for Orthophotography Planning provided technical advice. Images were collected with large format digital cameras in early 2024 and became available by late 2024. Image services are accessible, and data are downloadable through NC OneMap. CO24 was a 27-county orthoimagery project flown by 5 contractors, Spatial Data Consultants, Inc, Atlas Geographic Data, Inc. Surveying and Mapping, LLC, Surdex Corporation and The Sanborn Map Company Inc.. Metadata for the contractor’s imagery can be found here: Surveying and Mapping, LLC, Spatial Data Consultants, Inc, The Sanborn Map Company, Inc., Atlas Geographic Data, Inc. and Surdex Corporation. The data delivered by the contractors was in 6-inch ground resolution in 5,000 by 5,000-foot tiles, in uncompressed compressed format. Each tile is in a MRSID 20:1 compression format. Each tile is 6-inch ground resolution except for seven tiles in located in the Fort Bragg area.
Purpose:
This dataset was generated to provide a consistent reference map for base mapping and display in emergency 911 operations and GIS applications.
Supplemental_Information:
CO24 represents one year within the four year cycle to complete orthoimagery of the entire State of North Carolina. The bounding coordinates in this metadata file represent the bounding coordinates for all image tiles in the project area (CO24) as a whole, not an individual tile or even individual county.
