ERDAS ViewFinder

A free viewer for quickly displaying a variety of geographic imagery (including 16-bit data), rapidly reprojecting different data types into the same projection system, displaying multiple images in a single viewer, and working in multiple open viewers, at the same time. ERDAS ViewFinder uses technology developed by ERDAS for Stereo Analyst and ERDAS IMAGINE, such as embedding multiple views in single windows and reprojecting imagery on the fly. ViewFinder offers a range of image manipulation capabilities, packaged into a clean, simply designed user interface. Users can continuously roam, pan, and zoom the display imagery, at any scale. Additionally, users can overlay, query, measure, smooth, sharpen, and enhance imagery. The software supports ERDAS IMG, TIFF, TIFF World, GeoTIFF, and MrSID image files, including 16-bit and floating point data types.

New features in version 2.1

• Military Grid Reference System (MGRS) coordinate display in the Inquire Cursor dialog.
• Brightness and Contrast thumbwheels have been added for quick and easy image enhancement.
• Copy the contents of the Main View to the Windows clipboard.
• Data is then easily available for pasting into any application which uses the clipboard.
• Image information can be displayed, such as the number of rows, columns and bands, layer statistics, projection parameters, etc. Provision is also made for building image statistics and pyramid layers.
• Extended library of US and international projection systems for reprojecting to and from.
• Extended range of raster formats are supported, including JPEG (JFIF), ERMapper .ers and generic binary BIL, BIP and BSQ formats.
• Filter files on all raster formats to see all supported images in a directory.
• Quickly swap between non-stretched and 2 Standard Deviation modes of displaying the images. If an image has been pre-processed to stretch its data across the entire data range, then you may not want to have displayed it with the “Automatically Stretch Contrast” display option on and wish to swap to no stretch without redisplaying the image.
• Easily display separate files as a multi-band True Color image. Some data providers deliver multispectral images as separate files (one band per file). You can now open one of these bands as a True Color image and then use the Band Combinations dialog to add in other bands to the color guns.
• Initial display speed has been vastly improved. In some instances images may display an order of magnitude faster than in previous versions of ViewFinder.

All free plug-ins and viewers are offered as-is, with no support. We welcome bug reports on the products, but support is not guaranteed or implied.
