GIS Maps & Data
What is GIS?
According to ESRI, a Geographic Information System (GIS) links
locational and attribute information and enables a person to
visualize patterns, relationships, and trends. This process
gives an entirely new perspective to data analysis that cannot
be easily seen in a table or list format or on a paper map.
5 Components of GIS
-
Hardware - The computer, peripherals,
and sometimes servers on which the GIS operates
-
Software - Provides the functions and
tools required to store, analyze, and display data
-
Data - Data is stored
as vector, raster, or attribute data
-
Methods - The guidelines,
specifications, standards, and procedures for
collecting and analyzing data and applying GIS
-
People - GIS needs people
to ask the questions; choose, collect, and
analyze the data; and interpret the results
