Baltimore Land Use/Land Cover, 2002

2002 Anderson Level 2 land use/ land cover classification for Baltimore 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.

2002年巴尔的摩县安德森二级（Anderson Level 2）土地利用/土地覆盖分类数据集。本数据集最初依托高空航空摄影与卫星影像构建完成。2002年，针对马里兰州中部区域，研究人员利用2002年航空摄影数据更新了土地覆盖类型分类结果。城市土地利用类别则通过2002版MDPropertyView的地块信息完成进一步精细化调整。本数据集的最小制图单元为10英亩，制图分辨率为1:63360。本数据集属于包含221条巴尔的摩生态系统研究元数据记录的集合之一，这些元数据均指向一个地理数据库（geodatabase）。该地理数据库可在线获取，体量较大。经申请并达成特定协议后，可通过USB硬盘等介质线下交付。该地理数据库总容量约为51.4GB，包含160个文件夹内的4914个文件。尽管此类元数据记录的属性字段并不丰富，但鉴于其所关联的数据具备较高实用价值，仍予以公开共享。本数据集属于包含221条巴尔的摩生态系统研究元数据记录的集合之一，这些元数据均指向一个地理数据库（geodatabase）。该地理数据库可在线获取，体量较大。经申请并达成特定协议后，可通过USB硬盘等介质线下交付。该地理数据库总容量约为51.4GB，包含160个文件夹内的4914个文件。尽管此类元数据记录的属性字段并不丰富，但鉴于其所关联的数据具备较高实用价值，仍予以公开共享。
