Anne Arundel County Land Use/Land Cover, 2002

2002 Anderson Level 2 land use/ land cover classification for Anne Arundel County. Initially developed using high altitude aerial photography and satellite imagery. For 2002, land cover types were updated using 2002 aerial photography for Central Maryland. Urban land use categories were further refined using parcel information from the 2002 Edition of MDPropertyView. The minimum mapping unit for this dataset is 10 acres, the resolution is 1:63,360. This is part of a collection of 221 Baltimore Ecosystem Study metadata records that point to a geodatabase. The geodatabase is available online and is considerably large. Upon request, and under certain arrangements, it can be shipped on media, such as a usb hard drive. The geodatabase is roughly 51.4 Gb in size, consisting of 4,914 files in 160 folders. Although this metadata record and the others like it are not rich with attributes, it is nonetheless made available because the data that it represents could be indeed useful.

本数据集为2002年针对安妮阿伦德尔县（Anne Arundel County）构建的安德森二级（Anderson Level 2）土地利用/土地覆被分类成果。该数据集最初依托高空航空摄影与卫星影像开发完成。2002年，针对马里兰州中部区域，研究人员采用2002年航空摄影数据更新了土地覆被类型，并借助2002版MDPropertyView的地块信息进一步细化了城市土地利用类别。本数据集的最小制图单元为10英亩，制图比例尺为1:63,360。本元数据记录属于包含221条巴尔的摩生态系统研究元数据记录的集合之一，这些记录均指向一个地理数据库（geodatabase）。该地理数据库体量庞大，可在线获取。经申请并达成特定协议后，可通过USB硬盘等介质寄送该数据集。该地理数据库总容量约为51.4 GB，包含160个文件夹内的4,914个文件。尽管本元数据记录及其他同类记录的属性信息并不丰富，但鉴于其所代表的数据具备较高实用价值，仍予以公开。本元数据记录属于包含221条巴尔的摩生态系统研究元数据记录的集合之一，这些记录均指向一个地理数据库（geodatabase）。该地理数据库体量庞大，可在线获取。经申请并达成特定协议后，可通过USB硬盘等介质寄送该数据集。该地理数据库总容量约为51.4 GB，包含160个文件夹内的4,914个文件。尽管本元数据记录及其他同类记录的属性信息并不丰富，但鉴于其所代表的数据具备较高实用价值，仍予以公开。
