Analysis

Using GIS for analysis, you can find out why things are where they are and how things are related. You can get more accurate and up-to-date information, and even create new information that was unavailable before. Having this information can help you gain a deeper understanding of a place, make the best choices, or prepare for future events and conditions. Geographic analysis tasks may involve:

  •    mapping where things are
  •    mapping the most and least
  •    mapping density
  •    finding what's inside
  •    finding what's nearby
  •    mapping change
