The city and county of Denver, Colorado, provides many location-based services to its residents, businesses, and visitors. Making this information available online and accessible to a broad audience increases the level and quality of services provided to the public. To meet the diverse present and future needs of Denver's many city agencies and departments, an extensible integrated mapping and reporting architecture was created using Active Server Pages (ASP) and ArcIMS.

 

Records Management System and Mobile Data GIS Data Integration
In support of the Records Management System (RMS), DenverGIS has converted street centerline data into Versaterm's proprietary format, and established a program for regular updates.  GIS data has been loaded on to DPD Mobile Data Terminals (MDT) for mapping and RMS address validation for police reports.  Updated regional street centerline data has been acquired, conflated to the Denver Street layers, and formated to support the 911 Visicad computer aided dispatch software.

Public Works
Highway Users Tax Fund
Each year, the 311 Cities and Counties of Colorado receive approximately $150 million from oil and gasoline tax receipts to fund maintenance of local roads.  This money, collected through the Highway Users Tax Fund (HUTF) is distributed by the State Department of Revenue based on annual local road system reports submitted by eligible jurisdictions to the Colorado Department of Transportation (CDOT).  Submission of updated annual reports is a condition of continuing to receive these funds.  Denver's share is based on the number of street miles in the City and County of Denver as a percentage of all city mileage in the state.  The primary approach used to find the unclaimed streets was to linek the Denver Street Centerline GIS layer ot the CDOT/HUFT tabular inventory database accurate reporting of street mileage is critical to receiving a fair share of the total statewide funding for municipalities.  This project improves the quality, accuracy, and consistency of Denver's report and source data layers.  This project identified 114 (net) miles of previously unclaimed streets, an increase of $170,000 per year in HUFT funds to Denver - about a 6.5% RAISE!, and reduced staff time in the future to complete this report.

Technology Services
Address Validation web service
The City and Count of Denver requires accurate addressting to support daily business operations.  DenverGIS has developed an address web service that provides real-time access to Denver Address Database (DAD).  The address service supports consistent validation, formatting and identification of addresses across enterprise systems include 311 customer relationshiop management, PILAR and agency applications.  In addition, the address service integrates information from other sources including street intersections and postal addresses from the United States Postal Service (USPS).  The address service supports live address validation for 311 and enables real-time analysis, mapping and reporting of customer and case locations.  DenverGIS is leading efforts to implement the vision of a service-oriented architecture (SOA) that supports cross-platform, standards-based integration between enterprise systems.
