Have you ever heard of GIS mapping? Maybe not, but you have probably seen it at work. It stands for “geographic imaging system” and it is a technology frequently incorporated into the better mapping programs. It is capable of frighteningly complex analysis and calculations, and it always provides the user with a visual solution to the “problem” posed by the data. Put simply, it is a way for anyone in the engineering, building, surveying, or related fields to take whatever information they have and create a map from it.

Less than one hundred years ago this would have meant a survey team taking pinpoint measurements and making notes about natural features, landmarks, and distances. This would have been used to create a reasonably accurate one-dimensional map of the territory examined. Today, GIS mapping uses some of the same data sets, but will also use aerial photographs, satellite imagery, field data, and more to create true three-dimensional solutions instead.

Interestingly enough the better computer programs utilizing GIS mapping technologies will also link the user to as many valid data sets and resources as possible as well. For instance, some will steer the individual to the Internet and sites belonging to agencies like the USGS (United States Geological Survey) to get further information to use on a given project or “problem”.

When a GIS mapping program has a thorough range of data sets and some visual images, it will then create “layers” that will seamlessly blend and merge in order to develop a comprehensive, accurate, and clear map.

While GIS mapping is something used to create physical or computer based maps of geographic locations, the complex analysis is also something frequently used to map out things outside of landscapes and roadways. Many companies analyze their data to create models of various processes or functions too.

When using GIS mapping programs, however, it is best to seek out those with highly functioning graphic options and also to allow for familiar data sets to be processed easily through “batches” as well.
