Greenway Engineering provides a range of GIS services, including Custom Mapping, Data Attribute Analysis, and Location Analysis. The power of GIS is in the information associated with a given location. Some say that “location, location, location” is what is important, while others say that “information is knowledge, and knowledge is power.” GIS combines these two trains of thought to show where desired features are located, while symbolically or descriptively conveying information about the feature.
