ERDAS ViewFinder is a free viewer that quickly displays a variety of geographic imagery (including 16-bit data). Its simple interface provides a range of image manipulation functions and the ability to continuously roam, pan, and zoom imagery at any scale. Additionally, you can overlay, query, measure, smooth, sharpen, and enhance imagery. It also lets you rapidly reproject different data types into the same projection system, display multiple images in a single viewer, and work in multiple open viewers at the same time. It supports ERDAS IMG, TIFF, TIFF World, GeoTIFF, and MrSID image files, including 16-bit and floating point data types.
ERDAS ViewFinder uses technology developed for ERDAS IMAGINE and our Stereo Analyst products
(Stereo Analyst for ERDAS IMAGINE and Stereo Analyst for ArcGIS).
We welcome feedback on all products, but support is not guaranteed or implied for free products.
