Maps, Regional Data & GIS
Interactive Trail Map for Durham, NH [Disclaimer: Working Draft]
What is a GIS?
- In the most general sense, a GIS (Geographic Information System) is any system for storing, analyzing, and visualizing geographic information. A stack of topographic maps showing items-of-interest with clear plastic overlays for noting relationships among locations would thereby qualify as a GIS, and in fact the technology has its roots in precisely that arrangement.
- However, these days the term "Geographic Information System" usually refers to a computer implementation. Geographic data reside in a relational database, and analysis and visualization are accomplished through specialized software. Typically, the GIS software also includes the ability to print hardcopy maps; on-screen visualization of data is invaluable, but often a (printed) picture is still worth a thousand words!
