MD Property View 2003 A and T Database. For more information on the A and T Database refer to the enclosed documentation. This layer was edited to remove spatial outliers in the A and T Database. Spatial outliers are those points that were not geocoded and as a result fell outside of the Baltimore City Boundary; 416 spatial outliers were removed from this layer. The field BLOCKLOT2 can be used to join this layer with the Baltimore City parcel layer. 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.2003年MD物业视图A&T数据库。如需了解该A&T数据库的更多详情，请参阅随附文档。本图层已进行编辑处理，以剔除A&T数据库中的空间异常值(spatial outliers)。空间异常值指未完成地理编码(geocoded)、因此落在巴尔的摩市行政边界之外的点位；本图层共剔除了416个空间异常值。可通过BLOCKLOT2字段实现本图层与巴尔的摩市地块图层(parcel layer)的关联连接。本元数据记录是包含221条巴尔的摩生态系统研究元数据记录(metadata records)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。经申请并达成特定安排后，可通过USB硬盘等存储介质寄送该数据库。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。尽管本元数据记录及其他同类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，故仍予以公开。
