Carroll County Land Use/Land Cover, 2002

2002 Anderson Level 2 land use/ land cover classification for Carroll 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年安德森（Anderson）二级卡罗尔县（Carroll County）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开发构建。针对2002年的马里兰州中部区域，研究人员通过2002年航空摄影完成了土地覆盖类型的更新。城市土地利用类别则借助2002版MDPropertyView的宗地信息进行了进一步细化。该数据集的最小制图单元为10英亩，制图比例尺为1:63,360。本数据集属于包含221条巴尔的摩生态系统研究（Baltimore Ecosystem Study）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）。该地理数据库可在线获取，但体量较大。根据相关安排并提出申请后，可通过USB硬盘等存储介质寄送该数据集。该地理数据库总容量约为51.4吉字节（Gb），包含160个文件夹内的4,914个文件。尽管本元数据记录及同类记录的属性信息并不丰富，但鉴于其所承载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（Baltimore Ecosystem Study）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）。该地理数据库可在线获取，但体量较大。根据相关安排并提出申请后，可通过USB硬盘等存储介质寄送该数据集。该地理数据库总容量约为51.4吉字节（Gb），包含160个文件夹内的4,914个文件。尽管本元数据记录及同类记录的属性信息并不丰富，但鉴于其所承载的数据具备较高实用价值，仍予以公开共享。
