The University of Minnesota ForNet project has created ImageView, a World Wide Web-

based system that allows users to browse large raster data sets, including Landsat Thematic Mapper (TM) and Advanced Very High-Resolution Radiometer (AVHRR) imagery. ImageView provides users who would traditionally have little or no access to such databases with the ability to visualize, manipulate, and download images for a particular area of interest.

ImageView allows users to interactively explore an image or sets of images by setting parameters such as spatial extent, band combinations (where applicable), and display parameters (such as contrast). Working with sets of images, users can view landscape or seasonal variability in the imagery due to factors such as insect infestation, flooding, or human development.

ImageView works from ERDAS Imagine image files and was developed using the Imagine C Programmer's Toolkit.

General Interest / Research

The University of Minnesota ForNet project has developed MapServer, a software package for bringing interactive maps and associated attribute data to the World Wide Web. MapServer uses Geographic Information System (GIS) databases as the basis for creating maps and reports. Data owners can provide access to data for users who have traditionally lacked the hardware and software necessary to store, manage, and access GIS databases. Users can access data as they choose, and are not limited to predefined views or "canned" summaries. MapServer works with ESRI shapefiles and uses template files to describe map appearance and interface layout. Additional features include scale-dependent feature drawing, feature annotation, and automatic legend building.
