The Maryland Greenways Commission has been working since 1990 to plan, establish, and promote a statewide system of greenways. Greenways are natural corridors set aside to connect larger areas of open space and to provide for the conservation of natural resources, protection of natural resources, protection of habitat, movement of plants and animals, and to offer opportunities for linear recreation, alternative transportation, and nature study. In addition to Green Way Corridors, water routes know as Water Trails have been recognized as pathways for recreation and nature study. 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.

马里兰州绿道委员会（Maryland Greenways Commission）自1990年起便致力于规划、设立并推广全州范围的绿道系统。绿道（greenways）是指预留的自然廊道，用以连接更大面积的开放空间，同时实现自然资源保护、自然资源保护、栖息地保护、动植物迁徙，并为线性休闲、替代交通与自然研学提供契机。除绿道廊道外，被称为水径（Water Trails）的水路也被认定为休闲与自然研学的通道。
