Process_Step:
Process_Description:
County staff scanned original court maps into the GIS and rubber-sheeted them to fit the Allegheny County GIS Base Data developed from a flyover in 1992-93.
Process_Date: 1992-1994
Process_Step:
Process_Description:
During Y2K efforts of 1999-2000, data was transferred to Microsoft NT Server running ArcInfo 7 and was made available to county users across the network from a single location.
Process_Date: 2000
Process_Step:
Process_Description:
1361 tiles were edgematched to create a single seamless County coverage
Process_Date: 2000-2003
Process_Step:
Process_Description: Shapefiles were created from ArcInfo Coverages.
Process_Step:
Process_Description:
The 2000 Census resulted in changes to Ward lines based on population, which in turn caused reapportionment in Avalon, Bethel, Elizabeth, Indiana, McCandless, Mt. Lebanon, Ross, Sewickley and Upper St. Clair, changes were applied to the Voting District Data.
Process_Step:
Process_Description:
Wilkinsburg was reapportioned in 8/2004 under court order GD 04-5041; Pine had to redistrict in 9/2004 under court order GD 03-4772; Marshall had to redistrict in 2/2005 under court order GD 05-772. Changes were applied to the dataset by GIS Staff.
Process_Date: 2004-2005
Process_Step:
Process_Description:
South Fayette was reapportioned, changes were applied in 1st quarter 2007
