What are Buffers in GIS?

Buffers are used to expand the bounding region of the features in a layer. This creates a “zone” around the features at a specified maximum distance from all the vertices of the features. Buffering is useful for proximity analysis. For example, it could be used to help determine which areas may need assistance within a disaster zone or a city may need to find parcels that are adjacent to land plots to notify its citizens of upcoming constructions or zoning law changes.

Features that can be buffered include points, polygons, and lines. Map Suite has a number of APIs which allows developers to create powerful GIS apps with buffering tools. A simple online sample can be seen under Buffer. Want to customize this sample? Download it from here to start your evaluation and customize the sample to your specific needs.

Non-developers can download the Map Suite GIS Editor to start using the buffering functionality to perform proximity analysis and create new data. A complete overview on using the buffering wizard can be found here.
