Counting Your Change - Data Supply Chain Extends Data Feedback Mechanisms
Arizona DOT has been providing quality control feedback to data providers on roadway centerline issues in recent years as part of the statewide centerline data supply chain project. Recently, ADOT has added a "change detectionâ€ data comparison mechanism as a service at the AZGEO Clearinghouse. E-9-1-1 data custodians can now submit their data to the AZGEO servers and have a data comparison, as well as a quality assurance, report returned in an unattended fashion. This presentation will contain a quick refresher of the original effort followed by an introduction on how data providers can get an assessment of change between a dataset of 2 differing vintages.
