Data Set Description:
Patrol Areas (Sectors) are aggregations of patrol districts (and, logically, of beats). These groupings help dispatchers make decisions and also organize the officers below their senior commanders.
Non-standard Attributes in table:
- U_ID: Provides the user with a unique indentfying number for each polygon in the layer.
- POL_SECT: A sector number assigned by the Oakland Police Department.
Data Source History:
Joanne Ward, OCIS, created a field in the police beats layer that indicated which sector each beat was in. Using this field, Julia Howlett (JRH) unified veats in the same sectors (now know as Areas) using ArcInfo's "region" tools.
John Burgess of OPD made linework and attribute changes to update the beats from 57 to 34. When the streets layer's accuracy improved, Julia Howlett transformed the updated polsect shapefile into a coverage and made sure it matched the accuracy of the Streets coverage.
No security restrictions.
No updates scheduled.
Thomas Cave (OPD) updates linework and attributes using Arcview 3.0. The updated shapefiles are then transformed into coverages by OCIS GIS staff and redistributed.
