St. Charles County, Missouri – St. Charles County’s Information Systems Department launched a redesigned online Geographic Information Systems (GIS) Mapping Service in late 2016 with one feature left to complete – the ability to access the site on mobile devices.

Well, get ready to fire up your tablet and smartphone – the mapping service is officially mobile-friendly.

“This is the first time our public mapping application has been optimized for mobile devices, so it is a huge advancement in functionality,” says Mark Duewell, Manager of GIS Services. “We hope this improvement will encourage more citizens to use the site and discover all its capabilities.”

The GIS Mapping Service allows users to research and view a wide variety of map-based data about the community, including:

  • County and municipal boundaries and jurisdictions, roads and other thoroughfares.
  • Assessment and parcel data, as well as Google Street Views.
  • Voting districts, County Council districts, boundaries for school districts and utility service providers, zoning information, park trails, physical features and topography, and more.
  • To view the site on a mobile device, users enter the same mapping service URL, The mobile site works across all platforms and internet browsers, and features the same tools as the desktop version. The geo-location feature is the only new tool specific to mobile devices.

In addition to the mobile capabilities of the mapping service, Information Systems has a redesigned site for its Geo-Data and Mapping Hub, formerly called the Open Data Portal, which originally launched in late 2016: Along with providing another way to access the GIS Mapping Service, the site houses publicly available geospatial data, maps and applications published by GIS Services. Geospatial data can be searched, browsed and downloaded in several formats, and PDF maps are available for download. Additionally, there are links to other geospatial sites and sources of mapping data. The improved site organizes this information in a more functional and organized format for users, and allows room for future growth.

“The hub will enable us to continually expand our data and maps to the community in an easily accessible platform,” adds Duewell.

GIS Services continues to encourage the public and business community to provide feedback about these sites. “We want to make these sites easily accessible and usable for all our citizens,” says Simon Huang, Director of Information Systems. “Ideas and suggestions for improvement are much appreciated.”
