GIS users have a wide range from hardware and software engineers to resources and environmental scientists, policy-makers, and the monitoring and implementing agencies.
Detailed Explanation
This chunk highlights the diversity of people who use Geographic Information Systems (GIS). It includes not only technical experts, such as engineers who work on the hardware and software needed to run GIS, but also professionals in various fields such as environmental science and public policy. These individuals rely on GIS technology to perform their roles effectively, underlining the interdisciplinary nature of GIS.
Examples & Analogies
Think of GIS like a toolbox. Just as a good toolbox has different tools for carpenters, plumbers, and electricians, GIS has tools for a range of professionals, enabling them all to solve unique problems in their fields. For example, an environmental scientist might use GIS to track wildlife habitats, while a city planner might rely on it to design more efficient transportation routes.
The Role of GIS in Decision Support Systems

These cross-section of people use GIS to evolve a decision support system and solve real time problems.
Detailed Explanation
This chunk describes the essential role of GIS in supporting decision-making. A decision support system is a software application that helps users make informed choices by analyzing data. GIS enhances these systems by providing a spatial dimension to the information being analyzed. This means users can visualize data in relationships to geographical locations, enabling better-informed decisions.
Examples & Analogies
Imagine a city facing severe traffic issues. Using GIS, traffic engineers can analyze traffic patterns, identify problem areas, and visualize how changes to road layouts or traffic signals might affect flow. It's similar to using a map to find the best way through a maze โ GIS helps visualize and navigate complex situations efficiently.
Understanding Procedures in GIS

Procedures include how the data will be retrieved, input into the system, stored, managed, transformed, analysed and finally presented in a final output.
Detailed Explanation
This chunk outlines the general procedures involved in using GIS technology. Procedures are crucial steps that guide how data is handled within the system, starting from data retrieval to how it gets displayed. Proper procedures ensure that the data used in GIS remains accurate, up-to-date, and useful for analysis.
Examples & Analogies
Consider baking a cake. Just as you need to follow specific steps (gathering ingredients, mixing, baking, and decorating) to ensure a successful cake, GIS involves a series of critical steps to ensure the data yields useful insights. If you skip a step in either process, the final result might not turn out as expected.
