ENVI is a software application commonly used in the field of remote sensing and geographic information systems (GIS). It is designed to process and analyze satellite imagery and other geospatial data for the purpose of environmental and natural resource management. The name "ENVI" is an acronym for Environment for Visualizing Images.
ENVI provides a comprehensive set of tools and functionalities that allow users to explore, manipulate, and interpret various types of imagery. It supports a wide range of image formats, including multispectral and hyperspectral data, and can handle large datasets with efficient processing capabilities. The software offers image enhancement techniques such as pan-sharpening, atmospheric correction, and georeferencing, which help to improve the quality and accuracy of the displayed images.
ENVI also includes advanced image analysis tools, such as classification algorithms, vegetation indices calculation, change detection, and terrain analysis. These functionalities enable users to extract meaningful information from the imagery, identify and map land cover types, monitor changes in the environment, and assess various spatial patterns and relationships.
Furthermore, ENVI supports integration with GIS software, allowing for the combination of image analysis results with existing vector data and the generation of spatially referenced outputs. It also provides functionality for spatial modeling and geospatial analysis, enabling users to perform complex operations and generate useful outputs for decision-making and planning processes.
Overall, ENVI is a powerful software tool that facilitates the exploration, analysis, and interpretation of geospatial data, particularly satellite imagery, for the purpose of environmental management and research.
