News Releases

World basemaps

 1. Global Satellite Imagery - Earth Land Surface 2000 Ver. 3 from 2014 update

  • 14.25/15/30/60/90m-resolution, natural and/or false-colour
  • Complete six (6) data sets, multiple styles
  • Unique global mosaics at 30m-resolution (image size: 1,296,000 x 648,000 pixels; file size: 2.29 Terabytes in raw binary; format: optimised JPEG2000), ready-to-use and cost-effective

          - Global mosaic Style 1 (ocean area: uniform colour, e.g. black)
          - Global mosaic Style 2 (ocean area: bathymetric shaded relief)
          - Global mosaic Style 3 (land area: 3D texture demo; ocean area: shaded relief)

Anyone even with little or no geospatial experience is able to use our large-sized, GIS-ready global mosaics; it can be as easy as opening files! We show you how. 

"Data+Software" model for system developers and integrators.

Generation of web mapping tilesets (e.g. Google Map Tiles, Bing Map Tiles and OpenStreetMap - OSM Tiles). All you need is a web server or scalable cloud-based solutions (e.g. Amazon Web Services) to host our colourful and sharp world basemaps.

2. Global Elevation Data - Upgraded

  • Free 90m-resolution near-global SRTM mosaic with gaps filled
  • Global elevation mosaic resampled at 90m-resolution (image size 432,000 X 216,000 pixels) and shaded-relief basemaps produced under a range of beautiful colour schemes and various hillshading settings. Each large file in JPEG2000 is easy to use with GIS. Nine shaded-relief basemaps.
  • Unique global elevation shaded relief maps resampled at 30m-resolution (image size 1,296,000 X 648,000 pixels): examples

3. Overlay with global vector data (e.g. OpenStreetMap - OSM)

  • global mosaics at 30m-resolution to fuse with OpenStreetMap

DOS-based Utility Programs

17 June 2013: Spectral Transformer for Landsat-8 imagery, three standalone tools for rapidly making 30m- and 15m-resolution, colourful Landsat-8 imagery composites

2 February 2010: DOS-based HighView upgraded (version 3.1), a tool for ultimate image fusion of high-resolution satellite imagery, including Pléiades, WorldView-2, QuickBird, GeoEye-1 and IKONOS.

  • Advanced image pan-sharpening
  • Adaptive image stretching

17 August 2007: Spectral Transformer Fc2Tc-CIR, a tool for converting popular colour infrared imagery (e.g., SPOT-5, ASTER) 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., Pléiades, WorldView-2, QuickBird, GeoEye-1, IKONOS, KOMPSAT-2, FORMOSAT-2, SPOT-5 and ALOS).
