Description: Description:GMA’s (Geographic Market Area’s) define the geographic areas within which home sales will be compared during the reassessment analysis. GMA’s are determined primarily by differences in sale prices, housing stock and/or geographical factors. As GMA’s are created based on the specific market conditions and the assessment year, GMA’s should be analyzed and updated at regular intervals based on the fluctuating market conditions and before creating reassessment models.GMA’s have been sporadically redefined by a subjective process by the OPA staff.

Description: Summary:Metes and bounds description of an area.Features Updated: 2/08/2013Attributes Updated: 2/08/2013Metadata Updated: 2/13/2013Update Frequency: WeeklyPublic= YAbstract:When a deed is recorded, its metes and bounds description (Legal Description) is checked against the official registry for changes or confirmation.There are over 5000 registry maps representing the entire county of Philadelphia. Every metes and bounds description is assigned a 10 digit registry number. The first 6 digits represent the map number. The last 4 digits represent the parcel number. Maps with an ‘S’ in the registry number include everything south of Market Street. Maps with an ‘N’ in the registry number include everything north of Market Street. When a consolidation or subdivision occurs it is given the next highest parcel number on that registry map. Parcel Remainder: A subdivided parcel where no metes and bounds description was recorded, mathematically closing the remaining portion of area. Those parcels retain there original registry number until a deed confirming the remaining piece is recorded. Inactive parcels are metes and bounds descriptions which have been consolidated or subdivided in total. There relevance lies in there historical value.Data Development:Polygons are created by georeferencing survey plans into Arcmap. Or created manually using the metes and bounds description written in the deed.

Description: The TIGER/Line Files are shapefiles and related database files (.dbf) that are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line File is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. Block Groups (BGs) are defined before tabulation block delineation and numbering, but are clusters of blocks within the same census tract that have the same first digit of their 4-digit census block number from the same decennial census. For example, Census 2000 tabulation blocks 3001, 3002, 3003,.., 3999 within Census 2000 tract 1210.02 are also within BG 3 within that census tract. Census 2000 BGs generally contained between 600 and 3,000 people, with an optimum size of 1,500 people. Most BGs were delineated by local participants in the Census Bureau's Participant Statistical Areas Program (PSAP). The Census Bureau delineated BGs only where the PSAP participant declined to delineate BGs or where the Census Bureau could not identify any local PSAP participant. A BG usually covers a contiguous area. Each census tract contains at least one BG, and BGs are uniquely numbered within census tract. Within the standard census geographic hierarchy, BGs never cross county or census tract boundaries, but may cross the boundaries of other geographic entities like county subdivisions, places, urban areas, voting districts, congressional districts, and American Indian / Alaska Native / Native Hawaiian areas. BGs have a valid code range of 0 through 9. BGs coded 0 were intended to only include water area, no land area, and they are generally in territorial seas, coastal water, and Great Lakes water areas. For Census 2000, rather than extending a census tract boundary into the Great Lakes or out to the U.S. nautical three-mile limit, the Census Bureau delineated some census tract boundaries along the shoreline or just offshore. The Census Bureau assigned a default census tract number of 0 and BG of 0 to these offshore, water-only areas not included in regularly numbered census tract areas. Some boundary details clarified by Philadelphia City Planning Commission May 2011
Description: This dataset is a combination of both bike racks installed in 2008 as a result of Adopt-a-rack program and racks installed by converting parking meters by the Philadelphia Parking Authority. Those racks installed in 2008 as part of the City's first Adopt-a-rack program were requested by civic and business associations who "adopted" them and promised to clear abandoned bikes, remove graffiti and maintain them if they were damaged. These bike racks are in the style of 'staple' or 'hoop' racks.The PPA racks are those mounted to the former parking meter posts. They are the green discs that have been installed through Center City and parts of University City.The PROJECT field defines the associated project of installation, either Adopt-a-rack or PPA.The STAND_ADD field is most appropriate for address locating or geocoding purposes.Please note the field NUM_RACKS represents the number of racks at a given address. Each record may represent more than one bike rack.
