GeoSage is pleased to release RGB Image Stretching Tool, a time-saving
utility program for versatile image stretching.
Image stretching is arguably the most common task in remote sensing
image analysis. Almost all remote sensing software programs contain a
suite of well-known stretching methods such as histogram stretching,
Gaussian, Equalization, and Square Root. So, why another tool on the
As an experienced image analyst would tell, to produce a visually-
appealing RGB composite from raw imagery with true radiometric
reflectance is often tedious, involving the trials of many image
stretching options available. Choosing a suitable method and related
parameters is highly unpredictable, and it is fairy common to take
dozens of minutes or even hours to produce a desirable result.
RGB Image Stretching Tool is an efficient DOS-based utility program
and contains both linear and non-linear stretching options. Users can
define a set of band-specific, adaptable parameters for both options
in a single run.
RGB Image Stretching Tool analyzes 8- or 16-bit multiple-band GeoTIFF
inputs, and outputs 3-band, 8-bit RGB composite in GeoTIFF format with
a single image planar configuration.
RGB Image Stretching Tool runs super-fast. Processing 8,500+ Landsat
ETM+ scenes with a global coverage would take less than 24 hours on a
typical office PC.
A numbers of useful tips and a set of default parameters are also
provided for advanced image stretching.
Users of mainstream GIS software such as MapInfo and ArcGIS and
general image manipulation software such as PhotoShop and ACDsee will
find this tool very useful and handy too. The processed RGB composite
can be directly displayed within applications, no hassles.
A fully-functional trial version is available GeoSage website
utility program called RGB Image Composition Tool.
