SUFA LULC, Baltimore City

Baltimore City vegetation data layer showing non-veg, grass, forests, and water areas. This layer was produced by MD DNR Forest Service and derived from 2001 IKONOS satellite imagery. See the attached file "BACI_SUFA_veg_paper.pdf" for more information. This layer was converted from raster to vector using the "generalize lines" option. As a result the features do not line up perfectly with the IKONOS imagery. For a more precise version refer to the raster dataset "sufa_veg_baci.img." 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.

巴尔的摩市植被数据图层涵盖非植被、草本、森林及水域四类地物。该图层由马里兰州自然资源部（Maryland Department of Natural Resources, MD DNR）森林服务局制作，基于2001年IKONOS卫星影像生成。详细信息请参阅附件文件"BACI_SUFA_veg_paper.pdf"。本图层通过「线条泛化（generalize lines）」工具完成栅格到矢量的格式转换，因此地物要素与原始IKONOS影像无法完全对齐。若需更高精度的数据版本，请参考栅格数据集"sufa_veg_baci.img"。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的集合，该集合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。经申请并达成特定协议后，可通过USB硬盘等存储介质寄送。该地理数据库总容量约为51.4 GB，包含160个文件夹下的4914个文件。尽管本元数据记录及其他同类元数据的属性字段较为有限，但鉴于其所关联的数据具备较高应用价值，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的集合，该集合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。经申请并达成特定协议后，可通过USB硬盘等存储介质寄送。该地理数据库总容量约为51.4 GB，包含160个文件夹下的4914个文件。尽管本元数据记录及其他同类元数据的属性字段较为有限，但鉴于其所关联的数据具备较高应用价值，仍予以公开。
