Specific problem areas include: accurate data on the disease and how it is reported; basic environmental data on vegetation, land uses, topography, rainfall, etc.; and demographic data on the movement of people. The second area relates to technology – specifically computer hardware, GIS software and training.
Q. What is the difference between global positioning system and geographic information system?
GPS stands for Global Positioning System. GPS uses satellites that orbit Earth to send information to GPS receivers that are on the ground. GIS is a software program that helps people use the information that is collected from the GPS satellites.

Q. What are at least three ways GIS can be useful?
Here are 20 ways GIS Data is used in Business and Everyday Life:
- Mapping.
- Telecom and Network Services.
- Accident Analysis and Hot Spot Analysis.
- Urban planning.
- Transportation Planning.
- Environmental Impact Analysis.
- Agricultural Applications.
- Disaster Management and Mitigation.
Q. Is GIS a good career?
GIS is an exciting and professional choice for people. If you are curious about exploring the world and knowing more about the environment, it is best to have a GIS career. You will be successful and will remain successful if you have a growth mindset and continue to learn and grow every day.
Q. What is the purpose and function of GIS?
A geographic information system (GIS) is a computer system for capturing, storing, checking, and displaying data related to positions on Earth’s surface. By relating seemingly unrelated data, GIS can help individuals and organizations better understand spatial patterns and relationships.
Q. What are the major functions of GIS?
Table6.1 A Classification of GIS Functions
| (i) | Data validation and editing, eg checking and correction. |
|---|---|
| (viii) | Buffer generation, eg calculating and defining corridors. |
| (ix) | Data searching and retrieval, eg on points, lines or areas, on user defined themes or by using Boolean logic. Also browsing, querying and windowing. |
Q. What are the application of GIS?
e.g. Google, GPS, Here all utilise maps for common use. Telephone/Network services: GIS Data is used to incorporate geographic data into the complex network design, planning, optimisation, maintenance and activities. It provides a location based service for engineering applications and customer relationship management.
Q. What are the basic principles of GIS?
- 1.0 INTRODUCTION. GIS is a computer-based system that is used in input, output, storage, manipulation, retrieval and analysis of spatial data.
- 1.1 SPATIAL DATA.
- 1.1.1 Spatial Data Representations.
- 1.2 DATA FORMAT.
- 1.3 DIGITAL ELEVATION MODEL (DEM)
- 1.3.1 TIN.
- 1.3.2 Interpolation.
- 1.4 GIS OPERATIONS.
Q. What are the key elements of a GIS?
A working GIS integrates these five key components: hardware, software, data, people, and methods.
- Hardware. Hardware is the computer on which a GIS operates.
- Software.
- People.
- Methods.
- Data.
- Space Segment.
- Control Segment.
- User Segment.
Q. What are the concept of GIS?
A geographic information system (GIS) is a system designed to capture, store, manipulate, analyze, manage, and present all types of geographical data. The key word to this technology is Geography – this means that some portion of the data is spatial.
Q. How is GIS used in surveying?
Surveyors use GIS to manage the entire planning aspect of a surveying project. GIS provides the tools necessary to research, develop, implement, and monitor the progress of a project and manage site location, environmental impact mitiga tion, eco nomic analysis, and other critical facets.
Q. Why is GIS needed?
GIS: What Is It and Why Do We Need It? GIS is a system of computer hardware, software, data, and personnel to manage, analyze, and present information about a location. GIS links maps to databases and creates a visualization of data, and allows interactivity between the map and the data in a database.
Q. What is the future of GIS?
GIS of the future may very well be in augmented reality and virtual reality. AR and VR use continues to grow as users become more comfortable with the technology, and this will lead to more and more developers integrating GIS capabilities into their applications, Benton said.
Q. Is Google Earth a GIS?
Google Earth provides search capabilities and the ability to pan, zoom, rotate, and tilt the view of the Earth. Google Earth is not a Geographic Information System (GIS) with the extensive analytical capabilities of ArcGIS or MapInfo, but is much easier to use than these software packages.
Q. Does Google Earth still exist?
Google Earth Pro is currently the standard version of the Google Earth desktop application as of version 7.3. The Pro version includes add-on software for movie making, advanced printing, and precise measurements, and is currently available for Windows, Mac OS X 10.8 or later, and Linux.
Q. Where does Google Earth get its images?
The satellite and aerial images in Google Earth are taken by cameras on satellites and aircraft, which collect each image at a specific date and time.
