Which term describes the integration of geographic information with data stored in a database?

• A. Geographical Information Systems (GIS)
• B. Emergency Service Zone (ESZ)
• C. Automatic Location Identification (ALI)
• D. Dual Tone Multi-Frequency (DTMF)

Answer: (A)

Geographical Information Systems integrate geographic data with descriptive data stored in databases, letting maps display not just locations but the related attributes and enabling spatial analysis. In emergency services, this means you can visualize incident locations, assets, routes, and service areas together, then run queries like which units are closest or where coverage gaps exist. The other terms refer to different ideas: an Emergency Service Zone is simply a defined service area, Automatic Location Identification is the system that links a caller’s number to a location, and Dual Tone Multi-Frequency is the signaling used to dial. So GIS best describes the integration of geographic information with database data.
