Components of Geographic Information System

A Geographic Information System (GIS) is a computer-based system designed to analyze, capture, manipulate, store, and present geographic data. It combines technology, data, and information to generate digital maps, charts, and reports. A typical GIS is made up of several components, each serving a distinct role in the system.

Data

  • Data is the lifeblood of any GIS, and without it, the system would be useless. GIS data come in various forms, including vector, raster, and tabular data. It can be obtained from various sources, including satellites, GPS, surveys, and public datasets.
  • Vector data are made up of points, lines, and polygons that represent real-world geographic features such as roads, buildings, rivers, and land parcels. On the other hand, raster data consists of a grid of pixels that represent continuous surfaces such as elevation, temperature, and precipitation.
  • Tabular data is data in the form of tables that correspond to specific locations on the map. It contains attributes related to the features shown in the map and can be linked to other types of data.

Software

GIS software is the platform that enables the user to perform GIS analysis and manipulation of geographic data. It enables the user to create, edit, store, analyze, and visualize geographic information. GIS software comes in two types: proprietary and open-source GIS software.

Hardware

GIS hardware forms the physical components that make up the system. It includes the computer, input devices such as keyboards, mice, and scanners, and output devices such as printers and plotters. In a GIS, the hardware must have the processing power and memory to handle large data sets and perform data analysis.

People

The people component is perhaps the most crucial part of a GIS. GIS cannot function in isolation, and it requires skilled personnel to operate, maintain, and interpret the data and results generated by the system. People involved in a GIS project may include surveyors, cartographers, analysts, database administrators, and GIS specialists.

Type of Data Description
Vector Data Data made up of points, lines, and polygons that represent real-world geographic features such as roads, buildings, and rivers.
