The ESRI Guide to GIS Analysis, Volume 1, demonstrates how geographic analysis with GIS can identify patterns, relationships, and trends that lead to better decision making. Using examples from various industries, this book focuses on six of the most common geographic analysis tasks: mapping where things are, mapping the most and least, mapping density, finding what is inside, finding what is nearby, and mapping what has changed. Written for both new and experienced GIS users, this book builds a foundation of the basic tasks needed to handle a wide range of analysis applications.0Introducing GIS analysis What is GIS analysis? Understanding geographic features Understanding geographic attributes Mapping where things are Why map where things are? Deciding what to map Preparing your data Making your map Analyzing geographic patterns Mapping the most and least Why map the most and least? What do you need to map? Understanding quantities Creating classes Making a map Looking for patterns Mapping density Why map density? Deciding what to map Two ways of mapping density Mapping density for defined areas Creating a density surface Finding what's inside Why map what's inside? Defining your analysis Three ways of finding what's inside Drawing areas and features Selecting features inside an area Overlaying areas and features Finding what's nearby Why map what's nearby? Defining your analysis Three ways of finding what's nearby Using straight-line distance Measuring distance or cost over a network Calculating cost over a geographic surface Mapping change Why map change? Defining your analysis Three ways of mapping change Creating a time series Creating a tracking map Measuring and mapping change Where to get more information Index
