GIS and Internet Mapping
A Geographic Information System (GIS) is “a computer-based system for capture, storage, retrieval, analysis and display of spatial (locationally-defined) data." (The National Science Foundation)
Internet Mapping is a web-based application allowing access to GIS data and tools using a web browser.
GIS data are – Organized into “layers”, or groupings of data of a common type (i.e.
soils, roads, fire hydrants).– Typically include spatial (map) and tabular (text) data– Spatially referenced, allowing maps to overlay– Often require GIS-based software
