GIS & Remote Sensing


A geographic information system (GIS) is a computer tool for mapping and analyzing features and events on Earth. GIS technology integrates common database processes such as statistical queries and analyzes into maps. On the other hand, remote sensing is the science of collecting data about an object or phenomenon without physical contact with the object.

Below are some of the differences between remote sensing and GIS


It is a topography and data acquisition technique

Remote sensing technology is used to acquire and collect data about an object or phenomenon without physical contact with the object or the observed phenomenon.

You can restore large amounts of data

Remote sensing technology can collect and retrieve large amounts of data about an object or phenomenon. The data can relate to various aspects of the object, including its position on the earth's surface.

Reduce manual fieldwork drastically

Remote sensing technology relies on technical tools to collect data in large areas that reduce manual work that otherwise many people might have had to do.

Allows data recovery in regions with difficult or impossible access

Remote sensing can restore data to places to which people have no access, e.g. B. in volcanic mountains, in the depths of the ocean and in several other places.

Enables the acquisition of additional data in a short time

With the help of remote sensing technology, large amounts of data can be acquired over a large area in a relatively short time. The data collected can be used to analyze various aspects of the object or area to be analyzed.

It is mainly used for data acquisition

Remote sensing technology is mainly used for data acquisition, which can then be analyzed to provide information about an object or phenomenon on the surface of the earth.

It has a more complex user interface

Remote sensing technology has a more complex user interface than a GIS system because it is mainly used as a data acquisition tool. Therefore, more qualified personnel is required to interpret the interface.

Includes a limited area of investigation

Remote sensing technology can collect data about a specific area of the earth's surface. However, the data collected would be limited to the respective area of investigation.

Less robust

Remote sensing technology is much less robust than a GIS system because it can only interpret data to a limited extent and is also more susceptible to damage.

Less ideal for communicating information between departments

Remote sensing technology is not a tool for communicating information between different departments because this type of information is not intended to be provided.


It is a computer system consisting of hardware and software

A GIS system is a computer system that consists of software that is used to analyze the data collected and the hardware on which the software is operated.

It can handle large amounts of data

Due to the large capacity of the software and a sophisticated personnel system for data analysis, a GIS system is designed in such a way that it accepts and analyzes large amounts of data at a certain point in time.

It can cover large areas of study

A GIS system is designed to cover an elaborated area of study because it is able to analyze extensive and complex information at the same time.

It can handle unlimited and frequent data processing

A GIS system is a robust system with which large amounts of data can be analyzed and which also allows unlimited data processing and changes without the risk of a breakdown.

Robust and less sensitive to damage

A GIS system is more robust in terms of its functionality and less susceptible to damage due to its compact design.

Faster and more efficient

A GIS system is more efficient in data processing due to the components developed in the system for data analysis.

It requires less staff, time and money

A GIS system is self-sufficient and can be used to analyze large amounts of data with much less time, money and resources. A single person can analyze large amounts of data to get more complex information.

Mainly used for data analysis

A GIS system is mainly used to analyze complex data and convert the huge data sets into more meaningful information that can guide decision making.

It has a simplified user interface

End-users use a GIS system that displays a simplified user interface that anyone can use to learn how to interpret tons of data in the system.

It is an ideal tool for communication between different departments

A GIS system is easy to use, which is why it is ideal as a preferred tool for communication between different departments because the interface is easy to understand.
