Summary: – Remote Sensing software is designed to process, analyse, and visualize data sensors capture on satellites, drones, or aircraft. Discuss 10 best Remote sensing software’s, and their features, advantages and disadvantages.
A Complete Overview of Remote Sensing Software
Remote sensing software is mainly used to work with images taken by satellites, drones, or aircraft. It helps users process and improve these images so that useful information can be extracted. Common tasks include image classification (like identifying land use types such as forests, water, or buildings), image enhancement (making features clearer), and detailed analysis (such as detecting changes over time). This type of software is essential in environmental monitoring, agriculture, disaster assessment, and other studies where understanding the Earth’s surface is important. Examples: ERDAS IMAGINE,
ENVI, SNAP (Sentinel Application Platform).
This software enables the interpretation of imagery and spectral data to extract meaningful information about the Earth’s surface, such as land use, vegetation health, water bodies, urban development, and environmental changes.
These tools support image classification, change detection, atmospheric correction, and feature extraction. Remote sensing software is widely used in environmental monitoring, disaster management, agriculture, forestry, and geospatial research.
