CHART WEB Site Development

Enterprise Information Solutions, Inc (EnterInfo) provided comprehensive IT and GIS services to the Coordinated Highway Action Response Team (CHART) center. EnterInfo’s responsibility was to develop an Intranet and Internet interface allowing Maryland State Highway Administration Emergency Operation Reporting System (EORS) personnel to access emergency operation information in real-time. The solution uses ESRI’s ArcIMS Objects to allow users to control the display and overlay of various GIS layers, sensor data, camera images, and dynamic message board displays. A partial list of the available information layers includes the highway base map, snow emergency plan status, construction and weather related road closures, and real-time road condition sensor information.

The original CHART maps were published using ESRI MapObjectsIMS. To improve map publishing efficiency, the map engine was converted to ArcIMS in the year 2000. According to the system log, the system successfully responded to 8000 map requestors per hour during peak uasge. To prepare for the increased demand for the CHART WEB site, CHART has contracted EnterInfo to upgrade its program platform to ASP.NET. The completed WEB site is expected to be one of the first statewide Internet mapping system in the nation powered by ASP.NET.
