So is GIS just computerized maps? "Where are residential properties in my city that are on a paved road, within 1 mile (walking distance) of a shopping center, not within or adjacent to flood hazard areas and also at least 250' above sea level?" No. GIS is also a very powerful analytical tool. GIS allows for spatial analysis That means that GIS can answer complex questions that involve the spatial relationship of features and events. Although this example may not seem like something you would want to know, it is a good example of how sophisticated you can be with your questions. GIS could answer this question in just a few minutes.
