Prior to deployment, Denver Maps was put through extensive user testing. A significant amount of time and resources was spent testing the application with both city and county employees, as well as Denver residents, to identify how the software was actually used and to see the flaws in the layout design. Users were given a set of questions about data that could be found in Denver Maps. Without seeing the application, they were asked to complete the tasks to find the answers. How these users went about answering the questions was recorded by members of the development team. Several rounds of testing occurred, and the application was modified before each round.
Before user testing was complete, the accessibility of Denver Maps was also tested using applications that helped identify barriers. Several sight-impaired people participated in user testing Denver Maps using screen readers. They helped identify where additional tags and descriptive text and links were needed.
How to market Denver Maps was a question asked many times prior to deployment. The site was first marketed internally. Denver Maps was discussed in meetings, e-mails, and demonstrations, creating a buzz about the project. Flyers were then distributed to the public at counters where customer interaction occurs. Once deployed, DenverGIS relied heavily on employees to tell customers about Denver Maps.
The result: Denver Maps has replaced almost all geographic mapping links that were previously available on the www.DenverGov.org Web site. Many agency Web sites now have links to Denver Maps. Denver Maps was deployed several months prior to GIS Day 2004. The event was used to show off the project and provide training to people visiting the department's first GIS Day celebration that was open to the public. Another significant marketing windfall occurred in November 2004 when the election commission placed a link on its Web site to Denver Map's election report. Thousands of people were exposed to Denver Maps when they used this report to locate their polling place.
Content management is one area that must not be overlooked when developing an Internet GIS site. It is important that the data presented to the public be up to date and accurate. Denver Maps relies on each agency to update and maintain its data. GIS data standards developed by DenverGIS are provided to all agencies that supply data to the corporate GIS. Using standards and a thorough data maintenance plan protects Denver Maps and other GIS applications from failing because data fields have changed or bad data is published to ArcSDE.
Denver Maps has become one of the most frequently visited sites in the city and county of Denver. Currently, Denver Maps averages more than 30,000 visits per month. It had more than 80,000 unique visitors during the first six months of 2005. Denver Maps received a first place in the Applications Fair at the 2005 Esri International User Conference and an honorable mention from the Public Technology Institute's 2004 Top 25 Technology Solutions awards.

Denver Maps was developed by DenverGIS in cooperation with Customer Information Services of the city and county of Denver.
