Lee (at the red eye on the map) committed to engage with Union troops, he could see only the troops in the light areas; everything shaded (the much greater part of the Union's strength) was invisible to him. Historians using personal accounts, maps of the battle, and a basic elevation layer were able to unlock the mystery of why Lee may have decided to go into battle facing such poor odds.\r\n\r\nThis article is an excerpt from\u00a0The ArcGIS Book<\/em>,Second Edition:\u00a010 Big Ideas about Applying The Science of Where<\/em><\/a>.\u00a0<\/em>The twin goals of this book are to show you what is possible with Web GIS and then spur you into action by putting the technology and deep data resources in your hands.

How Is Spatial Analysis Used?<\/h2>\r\nSpatial analysis lets you pose questions, derive answers from data, and then make informed decisions. The organizations that use spatial analysis in their work include state and local governments, national agencies, businesses of all kinds, utility companies, colleges and universities, and nongovernmental organizations (NGOs).\r\n\r\nHow do these organizations use spatial analysis? The list below touches on a few well-known uses:\r\n

What Can My Map Show Me?<\/h2>\r\nIn many cases, you are doing analysis just by making a map. You have a question you want the map to help answer: Where has disease ravaged trees? Which communities are in the path of a wildfire? Where are the areas of high crime? As with any analysis, when you make a map, you're making decisions about which information to include and how to present that information. Effective visualization is valuable for communicating results and messages clearly and in an engaging way.\r\n
