SAQUE: FEATURES AND BENEFITS

Color-coded address points that show the error incurred by the geocoding algorithm using the streets centerlines layer, taking the address points as references. The color-ramp goes from green (small error) to red (large error). If an emergency vehicle were to be dispatched to one of the red dots by a CAD system using this street centerline layer, it is likely that arrival on scene will be delayed. Thus, the map shows the risk of not finding an address and it could be used to prioritize the cleansing efforts.

• Brings all data sources to one standard and converts among standards, automatically
• Minimizes the inconsistencies among all GIS address data sources, automatically in bulk. Allows interactive users resolution for inconsistent addresses that cannot be resolved
• Clusters all data sources identifying duplicate records, and eliminates/merges records automatically or manually
• Uses geodatabase replication to move clean records to other departments or agencies.

Many legacy systems (computer aided dispatch, school bus routing, etc.) can only geocode using street centerlines. The example shows the geocoding results using an ESRI locator (red dot), Tele Atlas (purple dot) and GeoPlanning Services (green dot). Notice that the standard algorithms place the house at the other end of the block, even with are no quality problems associated with the base road centerline data used in this example.

• Transform logical to actual ranges and vice versa, automatically, or keep both
• Detect and fix street centerlines orientation, range overlapping and continuity issues
• Detect address points out of sequence or on the wrong side of the street
• Flag features as exceptions for certain rules when an exception is known to reflect actual conditions
