The main components of GIS

The main components of GIS are

GIS

1. Hardware

GIS Hardware is the physical devices that are part of the computer system that supports the analysis and mapping goegrafi. GIS consists of hardware

     Input data such as mouse, digitizer, scanner, camera
     If the data like a hard drive, processor, RAM, VGA Card
     Output data such as LCD, monitors, plotters, printers, screening.

2. Software

The software used to carry out the process of storing, analyzing, visualizing data both spatial and non-spatial. Are as follows:

     Tool to insert and manipulate GIS data
     Data Base Management System (DBMS)
     Tool to analyze data
     Tools for data display and analysis

3. Data

Consists of two components:

     Spatial Data

Spatial data is a real picture of a region that is on the earth's surface. Generally represented in the form of graphs, maps, pictures with a digital format and stored in the form of the coordinates x, y (vector) or in the form of images (raster) that have a certain value.

     Non-Spatial Data (Attributes)

Non-spatial data is in the form of data tables where the table contains information possessed by objects in the spatial data.

4. Human

Humans are the core elements of the GIS because humans are planners and users of GIS.

5. Method

The method used in GIS will be different for each problem. GIS is good depending on the design aspects and aspects of Real side.
