NC Orthoimagery 2024-2027

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). 2024-2027 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 3-band, natural color imagery collected by the NC Orthoimagery Program for any given area of North Carolina between 2024 and 2027. The imagery has a pixel resolution of 6 inches with an RMSE of 1.0 ft X and Y. Individual pixel values may have been altered during image processing. Therefore, this service should be used for general reference and viewing. This data is also available as a WMS service. Image analysis requiring examination of individual pixel values is discouraged. However, those needing analysis capability for this same time period can take advantage of the “analysis” versions of this service which are available in REST, WMS, and WCS formats. 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." To help determine which is most suitable, refer to this guide.注意：请勿通过此ArcGIS Hub（ArcGIS Hub）项目页面中的地图或下载工具下载影像，否则将得到模糊的正射影像（orthoimagery）。请通过瓦片（tiles）或县境镶嵌影像（county mosaics，2010年至当前年份）下载影像。 2024-2027年项目区域 北卡罗来纳州正射影像项目（NC Orthoimagery Program）每四年为一个采集周期，制作6英寸（15厘米）分辨率的正射影像。每年将飞行覆盖该州约四分之一的区域，以构建流式影像服务（streaming imagery services）、5000英尺×5000英尺的瓦片，以及压缩单文件格式的县境镶嵌影像。自2020年起，该项目开始采集第四波段——近红外波段（near infrared）的影像，结合原有的红、绿、蓝三个可见光波段，为影像探索与分析提供了全新可能。 本服务涵盖北卡罗来纳州2024年至2027年间任意区域的3波段自然色彩影像。该影像像素分辨率为6英寸，X、Y方向的均方根误差（Root Mean Square Error, RMSE）为1.0英尺。在图像处理流程中，单个像素的数值可能已被调整，因此本服务仅适用于通用参考与可视化浏览。该数据同样可通过Web地图服务（Web Map Service, WMS）获取。不建议使用本服务开展需要逐像素检视的图像分析工作。若有同期影像分析需求的用户，可使用本服务的“分析版”，其支持REST、WMS及Web覆盖服务（Web Coverage Service, WCS）三种格式。若需查询影像拍摄的具体日期，可使用影像日期查询应用程序或下载完整数据集。 查看最新影像 本平台还提供多款网络服务，可展示北卡罗来纳州任意地点的最新正射影像。这些服务支持通用浏览与栅格分析，涵盖多种通信协议，包括Esri专有协议（如REST、SOAP）及开放地理空间联盟（Open Geospatial Consortium, OGC）标准协议（如WMS、Web要素服务（Web Feature Service, WFS）、WCS）。用户可通过搜索“正射影像”与“最新”关键词查找此类服务。如需了解如何选择最适配的服务方案，请参考此指南。
