Question

a fire department needs to map the location of fire hydrants within the city limits as part of their emergency readiness plan. what general tool would best help the fire department to complete this task?
global positioning system (gps)
remote sensing
heat maps
geographic information systems (gis)
area analysis

Explanation:

• Global positioning system (GPS): Primarily used for determining precise locations (latitude and longitude) of objects or points. While it can help in getting the location of fire - hydrants, it doesn't inherently map them in a way that can be easily integrated with other spatial data (like city boundaries, roads etc.) for emergency planning.
• Remote sensing: Involves gathering information about an object or area from a distance (usually via satellites or aircraft). It can provide imagery of the area, but it is more about data collection from afar rather than mapping specific man - made features (like fire - hydrants) in a detailed, organized, and spatially - related database format.
• Heat maps: Represent data in terms of intensity (e.g., population density, crime rate intensity). They are not designed for mapping the exact locations of discrete objects (fire - hydrants) in a way that can be used for emergency response planning which requires precise location and spatial relationship data.
• Geographic information systems (GIS): A system designed to capture, store, manipulate, analyze, manage, and present all types of geographical data. It can take the location data (from GPS or other sources) of fire - hydrants and integrate it with other spatial data (city maps, building locations, road networks etc.). This integrated data can then be used to create detailed maps for emergency readiness, such as showing the proximity of hydrants to buildings, optimal routes for fire - trucks etc.
• Area analysis: A very broad term that could involve many non - mapping related analyses (like demographic analysis of an area). It is not a tool specifically for mapping the location of objects like fire - hydrants.

Answer:

Geographic information systems (GIS)
