Emergency Nurse Practitioner (ENP) Practice Test 2026 – Comprehensive All-in-One Guide to Exam Success

Latitude and longitude are most useful in the Geographic Information System (GIS), which is designed to capture, store, manipulate, analyze, manage, and present spatial or geographic data. In the context of Advanced Location Information (ALI), which involves determining the geographic location of a caller in emergency situations, GIS plays a crucial role.

GIS utilizes latitude and longitude to map locations accurately, which can be critical for emergency responders to pinpoint where to go quickly. This spatial data allows for better decision-making and resource allocation in emergency management.

While Wireless Phase II is relevant to locating emergency calls made from mobile phones, it specifically employs methodologies for identifying general locations rather than the broader application of geographic data that GIS provides. Thus, GIS is the framework that articulates how latitude and longitude are systematically employed for location services.
