What is a 'decision support system' in GIS?

A 'decision support system' in GIS is fundamentally designed to assist users in analyzing data to enhance decision-making processes. It integrates various data sources, analytical tools, and modeling techniques to provide insights and actionable information tailored to specific decision scenarios. By facilitating complex analyses, decision support systems enable users to evaluate alternatives, assess potential outcomes, and understand the implications of decisions in spatial contexts.

This system goes beyond simple data retrieval; it allows for sophisticated modeling and scenario analysis, which are critical when addressing multifaceted problems like urban planning, resource management, or emergency response. The ability to visualize data within these systems also enriches the decision-making experience, but the primary focus remains on data analysis to inform choices effectively.
