Project Goal
The District of Columbia’s Office of the Chief Technology Officer has utilized GIS for city-wide enterprise data and application services, as well as service delivery for residents, businesses, commuters and visitors. City employees such as firefighters use DC Atlas for information that better enables them to perform their work. Features range from location reporting to statistical information.
The city’s award-winning portal website, www.dc.gov, leverages GIS to guide people to points of interest in the nation’s capital, while also offering comprehensive information about those locations. The DC Guide website includes municipal data and business information. It gateways include:
• Find It – 40,000 businesses and 200 government service locations
• Get There – trip planner for directions
• Where You Live – type in an address, or select an area from a list, in any neighborhood, ward, or zip code
• Make a Map – create a customized map
• Real Property – find information about more than 170,000 properties
• Map Gallery – explore a gallery of the most popular maps
• Taxicab Fare Calculator - compute how much a taxi ride will cost
The Emergency Information Center (EIC) website provides official preparedness and emergency mode information featuring GIS-powered maps. In emergency mode, GIS maps can be created from more than 200 datasets for information on shelters, field medical care units or centers for missing persons.

Business Problem Solved
Before the DC Guide, residents and visitors had no web site for finding the location of all government services and all businesses in DC, and how to get to them. DC government websites provided information and addresses, but no maps and directions. Commercial web sites for DC highlighted selected businesses. The District wanted to provide residents, businesses and visitors with a centralized source for information, addresses, maps and directions.
The EIC had two main goals: 1) to give District residents important general information about what to do in various emergency situations, and 2) to provide official critical information specific to an ongoing emergency. The site provides a single access point to the following types of emergency information:
• Emergency alert notification
• Terror alert status from the federal Department of Homeland Security
• Educational materials
• Location of first responders
• Evacuation routes
• Real-time data on ongoing emergencies
• Location-based instructions for people with disabilities
• PDF maps of police stations, hospitals and fire stations
• Navigation to an area by entering an address, picking a landmark, picking a neighborhood or clicking on a map.
• During non-emergencies - Location of nearest emergency services such as medical centers, hospitals, police stations, firehouses and schools.
• Similar and additional information available during emergencies – This can include but is not limited to: open shelters, water distribution, ice, food, clothing, medication, volunteer training centers, field medical care units, center for missing persons.
