资源简介:

Vegetation (trees and grass) for parcels defined as private land within Baltimore City. Private land parcels consisted of all those parcels with land use (LU) codes except for the category "Exempt Commercial" (EC). Roads had no LU codes. No parcels with the following LU codes were present in Baltimore City: agricultural (A), county club (CA), marsh land (MA), non-perc land (NP), and town house (TH). LU codes were determined from the Maryland Property View 2003 A&T database. A cursory analysis of the parcel data indicated that errors of omission were present due to insufficient parcel data in certain block groups. Vegetation data used in this analysis came from the MD DNR Forest Service IKONOS derived Strategic Urban Forest Assessment (SUFA) vegetation layer.
