Maine Orthoimagery Regional Cumberland County 2001 (Imagery Layer)

Image Service | OGC WCS | OGC WMS | KMZ | Tile Download Contains high resolution color CITIPIX Ortho-rectified Digital Images (ODIs) from GLOBEXPLORER. These digital images result from ortho-rectification and mosaicking of scanned color aerial photographs. Each pixel represents a planimetric square 1/2 foot on a side on the ground. Digital file features include high quality ground-level georeferencing, derived from accurate positioning and geometric corrections, and provide a digital photographic map suitable for applications requiring a 1:1200 National Map Accuracy Standard (NMAS). Based on the CITIPIX nation-wide standard for urban aerial coverage, georeference and distribution, CITIPIX ODIs serve the GIS industry, state and local governments as well as private sector, supplying 6-inch (15-cm) ground pixel size map-accurate continuous digital photographic coverage.影像服务 | OGC WCS | OGC WMS | KMZ | 瓦片下载 本数据集包含来自GLOBEXPLORER的高分辨率彩色CITIPIX正射校正数字影像（Ortho-rectified Digital Images, ODIs）。此类数字影像由扫描彩色航空照片经正射校正与镶嵌处理生成，单像素对应地面上边长为0.5英尺的平面正方形区域。该数字文件具备高精度地面地理参考属性，其源于精准定位与几何校正流程，可生成符合1:1200国家地图精度标准（National Map Accuracy Standard, NMAS）要求的数字摄影地图，适配各类有此类精度需求的应用场景。CITIPIX ODIs基于CITIPIX在城市航空覆盖、地理参考与分发领域的全国统一标准，可服务于地理信息系统（Geographic Information System, GIS）行业、州及地方政府与私营部门，能够提供地面像素尺寸为6英寸（15厘米）的高精度连续数字摄影覆盖数据。
