ODU June 2026

Overview Campus June 2026 Aerial Imagery is a hosted ArcGIS image service that provides access to a single processed raster dataset for a local campus area in Web Mercator. The service delivers tiled imagery coverage through a REST interface and supports image and tiles access for fast display and retrieval. The dataset is a processed raster stored in Cache/LERC2D format with 3 bands and 8 bit unsigned pixel values. The imagery covers a compact area around campus in the Norfolk, Virginia region and supports analysis use through enabled image service capabilities. Geographic coverage is local, with an extent centered near campus in eastern Virginia. Band Characteristics The raster contains 4 thematic bands with athematic representation and histogram statistics available for the first three bands. Band 1: minimum 1, maximum 254, mean 99.94, standard deviation 57.21 Band 2: minimum 1, maximum 254, mean 99.81, standard deviation 53.85 Band 3: minimum 1, maximum 254, mean 87.35, standard deviation 59.55 Band 4: band present in the service metadata Raster Properties Pixel type: 8 bit unsigned integer Pixel size: 0.0380254631717853 map units Dataset format: Cache/LERC2D Compression: LERC Tile size: 256 x 256 Levels of detail: 8 cached levels, from scale 18395.9038165793 to 143.717998567026 Histograms: values range from 0 to 254 for the first three bands Tile cache: single fused map cache enabled for fast display Analysis access: image analysis is allowed Download access: copy and tile export are disabled Geographic Coverage The service covers a small local area in Web Mercator (WKID 102100 / 3857) with an extent that spans campus surroundings in eastern Virginia. Spatial reference: Web Mercator Auxiliary Sphere Extent: xmin -8495800.289634716, ymin 4422374.406297123, xmax -8493098.876462845, ymax 4424036.6513942145 Use Cases This service supports viewing, querying, identifying, and downloading imagery through ArcGIS image service operations. It also supports tiled access for efficient map display and can be used for campus-focused image review, spatial inspection, and raster analysis workflows within GIS applications.概述 2026年6月校园航拍影像（Campus June 2026 Aerial Imagery）是一项托管式ArcGIS影像服务（ArcGIS Image Service），可通过Web墨卡托投影（Web Mercator）访问弗吉尼亚州本地校园区域的单幅处理后栅格数据集。本服务通过REST接口提供分块影像覆盖范围，并支持影像与瓦片访问，以实现快速显示与检索。本数据集为经处理的栅格数据，以Cache/LERC2D格式存储，包含3个波段与8位无符号像素值。该影像覆盖弗吉尼亚州诺福克（Norfolk）区域内校园周边的紧凑区域，并通过启用的影像服务功能支持分析应用。其地理覆盖范围为本地区域，空间范围以弗吉尼亚州东部的校园附近为中心。 波段特征 该栅格包含4个专题波段，支持非专题表达，且前三个波段可获取直方图统计信息。 波段1：最小值1，最大值254，平均值99.94，标准差57.21 波段2：最小值1，最大值254，平均值99.81，标准差53.85 波段3：最小值1，最大值254，平均值87.35，标准差59.55 波段4：该波段存在于服务元数据中 栅格属性 像素类型：8位无符号整数 像素尺寸：0.0380254631717853 地图单位 数据集格式：Cache/LERC2D 压缩方式：LERC 瓦片尺寸：256×256 细节层级：共8个缓存层级，比例尺范围从18395.9038165793至143.717998567026 直方图：前三个波段的取值范围为0至254 瓦片缓存：启用单一融合式地图缓存以实现快速显示 分析访问：支持影像分析 下载访问：已禁用复制与瓦片导出 地理覆盖范围 本服务覆盖Web墨卡托投影（Web Mercator，WKID 102100 / 3857）下的小型本地区域，空间范围涵盖弗吉尼亚州东部的校园周边区域。 空间参考：Web墨卡托辅助球面（Web Mercator Auxiliary Sphere） 空间范围：xmin -8495800.289634716, ymin 4422374.406297123, xmax -8493098.876462845, ymax 4424036.6513942145 应用场景 本服务支持通过ArcGIS影像服务操作实现影像的查看、查询、识别与下载。同时支持分块访问以实现高效地图显示，可用于面向校园的影像审阅、空间检查以及GIS应用内的栅格分析工作流。
