Item Information

snippet:	DTS has been maintaining the County-wide bldg_ps (i.e. polygons) geography since the late 90's. Each building polygon is assigned an address label under the field name PS_LABEL which contains the addrnum and the bldg unit number if the building addrnum is a duplicate. This file is used by DFRS in Altaris View to show building addresses on a map. Address matching, and geocoding data tables with address information should use the ADDRNUM field when creating a geocode locator. Bldg files were first created in the early 90's for the county, by a contractor hired by the Maryland National Capital Park and Planning Commission (MNCPPC) to be included in Planimetric layers. It was used by MNCPPC to display buildings on QC maps to minimize MNCPPC's encroaching property lines. DTS, then known as DIST, maintains bldg_ps, a geographic base file created using MNCPPC's property and bldgs data . Property data was initially used to add premise addresses to bldg_ps geography. DTS enhanced and expanded the building layer to include premise addresses and preplan drawings for Montgomery County Fire and Rescue. The new geographic database is dubbed as bldg_ps. Using the Arc/Info GIS software, DTS enhanced the County bldg_ps to a level surpassing MNCPPC's Planimetric bldg data using such sources as State Department of Assessments and Taxation, Department of Permitting Services, Motor Vehicle Administration and the Internet for addresses and Pictometry Ortho photos to cartographically (and spatially) enhance the bldg_ps data layer. Some 34,611shape polygons were added to the 267,8474 bldg_ps database. As a result, a spatially accurate and cartographically pleasing bldg_ps file was generated. Since 2000, DTS staff has improved the accuracy of the bldg_ps file from 267,847 polygons without premise addresses, preplans and shapes, to 326,524 (as of 09/24/2012) polygons with premise addresses, preplans and shapes.
