An improved system and method for analysis and display of geo-referenced imagery overlaid with information such as vegetation health, land cover type and impervious surface coverage. In one aspect, an image analysis system creates a map of a selected area of land by overlaying information extracted from an image or images onto a base map or image. In another, a spatially-indexed image database is maintained having a plurality of images corresponding to a plurality of geographic locations; a user-specified geographic location is accepted through an interactive graphical user interface; a user-specified extraction analysis is accepted for application upon one or more images; a user-specified extraction analysis is automatically executed to extract overlay information from such images corresponding to user-specified geographic location(s); and extracted overlay information is overlaid on a geo-referenced image, and displayed though a graphical user interface.
