NC Orthoimagery 2020-2023 - CIR (WCS)

NOTE: DO NOT DOWNLOAD THE IMAGERY BY USING THE MAP OR DOWNLOAD TOOLS ON THIS ARCGIS HUB ITEM PAGE. IT WILL RESULT IN A PIXELATED ORTHOIMAGE. INSTEAD, DOWNLOAD THE IMAGERY BY TILE OR BY COUNTY MOSAIC (2010 - current year). 2020-2023 project areas The NC Orthoimagery Program collects and produces 6-inch (15cm) orthoimagery on a 4-year cycle. Approximately a quarter of the state is flown each year to develop streaming imagery services, 5,000' by 5,000' tiles, and compressed single-file county mosaics. Beginning in 2020, the State started collecting a fourth band (near infrared) of imagery which, when combined with the other 3 bands of red, green, and blue, opens new possibilities for exploration and analysis. This service contains 4-band (RGB+NIR) imagery collected by the NC Orthoimagery Program for any given area of North Carolina between 2020 and 2023 and is depicted using color-infrared (CIR). The imagery has a pixel resolution of 6 inches with an RMSE of 1.0 ft X and Y. The compression method (DEFLATE) used for this imagery maintains the individual pixel values so that this data is suitable for analyses. This data is also available as ArcGIS REST and WMS services. About CIR CIR is useful for environmental and land use monitoring because they can highlight features that are not as easily visible in standard visible light photographs. Some examples include assessing the health of vegetation, assessing soil moisture, determining water quality, and identifying man-made features. For those not requiring support for analysis, the NC Orthoimagery 2020-2023 image service may offer better appearance and performance. To find specific dates the images were captured use the imagery dates app or download the data. Viewing the latest imagery Several web services are also available that depict the latest imagery for any location in the state. These support general viewing and raster analysis and are offered in various protocols including Esri (e.g. REST, SOAP) and OGC (e.g., WMS, WFS, WCS). These can be found by searching using the terms "orthoimagery" and "latest."
