Detect and Monitor Changes Over Time

The ENVI product line provides an array of sophisticated tools for dynamically viewing the same location in two or more images simultaneously, as well as tools for automatically detecting changes.

Change detection tools include a wizard-like interface to guide you through typical change detection workflows and can work on original images or categorized images like classification or Feature Extraction output.

From soil erosion to urban development, change detection tools are appropriate for detecting all types of changes. The results of change detection analysis include not only maps of the detected changes, but also reports showing the area and percentage of different detected changes. The areas of change are easily overlaid onto other images, with or without transparency, to quickly highlight change.
