EP21 SA4 Orthoimagery in Wilson, Wayne, Johnston, Sampson, and Bladen Counties, North Carolina captured during leaf-off conditions in early 2021, 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 2020. The NC 911 Board funded the 2012 and 2013 acquisition as well as the statewide collection in 2010. The 2021 project is consistent with the Business Plan for Orthoimagery in North Carolina (https://ncgicc.net/Portals/3/documents/OrthoImageryBusinessPlan_NC_20101029.pdf) that recommends acquisition of one-fourth of the state (or 27 counties) per year in a four-year cycle. The products are orthoimagery in true color, 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 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 digital cameras in early 2021, image processing and quality control occurred through 2021, and products became available by mid-year 2021. Image services are accessible and data are downloadable through NC OneMap. The digital imagery for The EP21 SA4 area was acquired from January 29 to March 05, 2021. The orthophoto tile naming convention utilizes the NC statewide index and uses the following parameters:OF is the 2 digit product code, O=orthoimagery, F=Four Band (RGBIR)6io is the 3 digit pixel size for 6-inch imagery37 is the 2 digit NC ANSI (FIPS) code000 is the 3 digit alpha numeric custodian code, Code "000" represents state maintained data"00959502" is the map index number. It is an 8 digit SOS LRM numbering of the basic modular unit with millionth place digit.20190208 is the 8 digit date (YYYYMMDD) representing the starting flight date for the county0307R0 is the 4 digit data (MMDD) representing the ending flight date for the county followed by the revision number for that tile.Seamline polygons are also available in Shapefile format for the county. Each Shapefile contains the following fields: Study Area ID, Strip ID (flight line), Exposure ID, Date Flown.Technical reports were created across the project study area and include the following:Attachment C: Flight & Control Plan (shows maps, layouts & details for planned flight lines & survey control per study area)Attachment C-1: Control Surveys Rerport (shows final locations, descriptions & diagrams for survey ground control across the study area)Attachment D: Imagery Acquisition Compliance Report (provides flight acquisition maps, specifications & supporting documentation by AT block across the study area)Attachment E: Airborne GPS-IMU Post Processing & Aerotriangulation Report (provides flight details, state specification compliance table, software used, GPS-IMU summary tables, AT statistics and multiple supporting tables/files per AT block)In addition supporting documentation was created for each county and includes the following:Attachment F Report: Signed and Sealed Orthoimagery Delivery ReportAttachment G Report: Quality Review Issues and Resolutions ReportThis dataset was generated to provide a consistent reference map for base mapping and display in emergency 911 operations and GIS applications.The State of North Carolina and Wilson County shall not be held liable for any errors in this dataset, including visual content and positional accuracy of this imagery or image capture dates associated with the filename.
