How to use a GIS

Geographic Information Systems are extremely efficient useful tools; however one must have a clear understanding of what questions to ask as well as what answers they are looking for in order to properly uses a GIS. First, one should start by deciding specifically what information is needed, and framing that as a question. Next one should determine what type of data to use. Based on the initial question that was formed, an analysis method should be formed. Next you let the GIS run the data, and provide output. The final step is to study the analysis, and decide how to take action based on the results.
