Orthoimagery Seamlines Combined by Exposure Date for Northern Piedmont and Mountains 2022 (NPM22) in North Carolina
2021
North Carolina Center for Geographic Information and Analysis
Vector digital data
In 2022, on behalf of the North Carolina Center for Geographic Information and Analysis four contractors captured 6-inch pixel 4-band (RGB-IR) orthoimagery for the 26 Northern Piedmont and mountain counties in North Carolina. These contractors are Spatial Data Consultants, Inc., Sanborn Map Company, Atlas Geographic Data, Surdex Corporation, and Survey and Mapping (SAM). This file documents the mosaic of the imagery exposures and associated seamlines used to generate the collection of imagery by the contractors for the entire study area of North Carolina for the following counties , Alamance, Alexander, Alleghany, Ashe, Avery, Burke, Caldwell, Caswell, Catawba, Davidson, Davie, Forsyth, Guilford, Iredell, Madison, Mcdowell, Mitchell, Randolph, Rockingham, Rowan, Stokes, Surry, Watauga, Wilkes, Yadkin, Yancey; and the date each exposure was flown. Seamlines were converted to polygon shapefile format, checked for gaps and overlaps, attributed, and trimmed to the study area boundary. This dataset contains a polygon seamline index attributed with, Exposure date the season. These attributes were based on information collected from individual frames and from flight line datasets. This seamline dataset was created to identify the individual exposure frames and the seamlines that join these exposures together to generate the orthoimagery product for the Northern Piedmont and Mountains 2022 Project (NPM22). The purpose of this dataset derives information from the exploitation flight lines to provide the specific dates of imagery acquisition for each image frame.
