Forest areas by commercial type for Baltimore County and City circa 1914. Forest types identified include merchantable hardwoods, culled hardwoods, hardwood saplings, scrub pine, scrub pine saplings, and mixed hardwoods and scrub pine. Statistical data on the amount of saw timber per acre by forest type is also presented. In addition to showing the forest stand data the map has very detailed transportation, urban area, hydrological, and topographic features. The map was scanned at a resolution of approximately 4.3 meters, it was then georeferenced using 22 control points from 1:100000 hydrologic and transportation data and rectified to UTM Zone 18N, NAD83. The cell size on the rectified map was set to 10m in order to reduce the size of the rectified map. Please exercise caution when using this dataset since significant positional inaccuracies do exist. 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.
