A geographic information
system, also known as GIS.
Collects, stores, analyzes,
organizes, modifies and
presents data that are related to
location.

Component
GIS hardware include different devices including the
central piece of system equipment, the workstations.This is the main commanding hardware of the entire
system.
All connections to equipment that collect data.
Devices that interpret or convert data and
The system software are managed in the centralworkstation.
Web servers are also integral pieces of equipment in
GIS systems.

ComponentContd
Software makes up a third of the GIS system. It is
mainly responsible in handling, creating, modifyingand analyzing data.
Other features that do specific tasks for specific
applications can be added like software add-ons.
The last third of the GIS system's component trinity
is the data itself.
This is the heart and soul of geographic
information systems. It includes geographic and
vector data, the lifeblood of the entire GIS
ecosystem.

How toManage GIS
The most common way for GIS systems to handle
data is to have it Computerized form(digitized).
Hard copies of data will be digitized, allowing the
system to modify, organize, analyze and copy data to
be easily accessed by multiple services at any time.
Digitized data makes it easy for users to overlay
several map views such as in Google Maps into one
multilayer map.

Contd.
GIS systems present location data that includes
representation of roads, elevation, land mass
and bodies of water using different graphic
modes including 3D color images.
It uses simple geometric shapes like straight
lines and curves to represent direction,
boundaries and certain landmarks.
