Remote Sensing Analytics


Remote Sensing Analytics refers to the process of acquiring, processing, analyzing, and interpreting data from a distance, often using satellite or aircraft technology. It allows geographical information to be collected over large areas in a short period and without disturbing the environment or subjects under study.

What is Remote Sensing Analytics?

Remote Sensing Analytics is a critical branch of Geographic Information Systems (GIS) that uses scientific tools to observe and interpret physical characteristics and patterns from a distance. The information gathered through remote sensing is usually in the form of digital images and data associated with geographic coordinates, which allows for precise spatial analysis.

The process primarily involves the detection and measurement of the reflected or emitted energy from the Earth's surface. This data is then converted into useful information about the characteristics, features, and phenomena of the Earth. The different types of remote sensing include aerial photography, satellite imagery, thermal imaging, radar and sonar.

Remote Sensing Analytics has diverse applications across different fields, including environmental monitoring, agriculture, urban planning, meteorology, military surveillance, among others.


What types of data can be collected using Remote Sensing Analytics?

The type of data collected varies depending on the sensor used and the target of the sensing. It can range from imagery data, including color and infrared, thermal data, radar data, and light detection and ranging (LiDAR) data. The data highlights various aspects such as vegetation, temperature, moisture, elevation, built surfaces, etc.

How is Remote Sensing Analytics applied in environmental monitoring?

In environmental monitoring, remote sensing analytics can provide valuable information about soil conditions, vegetation cover, water quality, and environmental changes. For example, analyzing satellite images can help assess the impact of climate change, measure deforestation rates, or identify water pollution sources.

How accurate is Remote Sensing Analytics?

The accuracy of Remote Sensing Analytics depends on the type of sensor used, its resolution, and the techniques used to process and interpret the data. However, the vast majority of modern remote sensing tools have very high accuracy levels, often within a few metres or less for spatial accuracy.

What challenges are associated with Remote Sensing Analytics?

Some challenges associated with Remote Sensing Analytics include the costs associated with acquiring high-quality sensor data, technical skills required to process and interpret the data, difficulty in accessing certain geographical regions, and temporal limitations for capturing changes over time. Also, factors like weather conditions or the presence of clouds can affect the quality of satellite images.
