Bufferīuffer is one of the easiest tools to understand and one of the most commonly used. By understanding the categories of tools, you are better prepared to use tools that are not specifically introduced in class.
Like we did for Overlay Analysis tools, we are going to take a look at some examples of some Proximity Analysis tools, not with the intention of memorizing how each tools works, but instead to better understand the category of these tools. In combination with Overlay tools, the tools found in the Proximity Analysis toolbox make up the majority of tools GIS technicians use per project. Similar to Overlay Analysis as applied to both vector and raster datasets, Proximity Analysis tools are designed to examine spatial distribution relationships between datasets, answering questions such as: “How far is this feature from this other feature?” “How many homes fall within this particular fire protection district?” “What is the most cost efficient delivery area based upon our delivery fee?” and “How long does it take to drive from Denver to Eldora Ski Resort?”.
