GeoSage: To view our land more clearly and colourfully

Data Products:

15 April 2009:

Two unique, near-global imagery mosaics are now available for GIS integration: large-size and low-cost

1. Seamless 90m-resolution shaded-relief maps derived from SRTM data and produced under a range of beautiful colour schemes and various hillshading settings. Each large file (image size 432,000 by 139,200 pixels) is in JPEG2000 format and easy to use with any GIS.

2. Natural-colour satellite imagery mosaics at 90- and 60-m resolutions: Two large files (image sizes 432,000 X 180,000 pixels and 648,000 X 270,000 pixels) are in JPEG2000 format. Now NO extra efforts are required to have seamless, medium-resolution global mosaics in GIS applications.

26 June 2006: Natural-colour global satellite imagery mosaic tiles at a spatial resolution of 30m (or 28.5m) available.

DOS-based Utility Programs

1 July 2008: DOS-based HighView (version 3.0), an efficient tool for ultimate image pan-sharpening of high-resolution satellite imagery such as QuickBird, IKONOS, GeoEye-1 and future WorldView-2. (new)

17 August 2007: Spectral Transformer Fc2Tc-CIR, a tool for converting popular colour infrared imagery (e.g., SPOT-5) into eye-catching natural colour scenes, with six methods / colour templates included.

2 May 2007: Spectral Transformer B742B321 a unique tool for easily making natural-colour, 14.25m medium-resolution global imagery from false-colour Landsat ETM+ bands 7/4/2 in NASA GeoCover series ...

GUI-based HighView (still available)

2 Feb. 2006: GUI-based advanced image fusion and pan-sharpening software HighView (version 2.5). HighView successfully merges low-resolution multispectral bands with high-resolution panchromatic band of recent satellite images (e.g., GeoEye-1, QuickBird, IKONOS, KOMPSAT-2, FORMOSAT-2, SPOT-5 and ALOS).
