We promote some easy-to-use image analysis software tools in a hope that they will help explore our innate curiosity with the amazing images of the Earth as seen from space.

 

1: For popular public-domain Landsat-8 and Sentinel-2 satellite imagery

 

GUI- and DOS-based tools

  • Step 1: Landsat8_RGB.exe
  • Step 2: Landsat8_Stretch.exe
  • Step 3: Landsat8_Fuse.exe
  • Step 4: Landsat8_Feature.exe

GUI- and DOS-based tools

  • Step 1: Sentinel2_RGB.exe
  • Step 2: Sentinel2_Stretch.exe
  • Step 3: Sentinel2_Fuse.exe
  • Step 4: Sentinel2_Feature.exe

Software installation instructions

Step 1: Install Microsoft VC++ 2015 Redistributable x86 library (vc_redist.x86.exe) the software needs. (1) It is already included in the software download, and just double click vc_redist.x86.exe for its installation; (2) It is also available at Microsoft Download Centre; (3) Alternatively, it can be directly downloaded here (file size 13.1MB). If your computer already has this library, there is no need for its fresh installation.

Step 2: Required for processing compressed Landsat-8 data downloaded from Amazon Web Services (AWS): Install the most popular open-source GIS software QGIS. Spectral Discovery for Landsat-8 Imagery will use the GDAL_translate.exe tool included in QGIS to convert downloaded Landsat-8 data from compressed GeoTIFF format to uncompressed, analysis-ready GeoTIFF format. (Ignore this step if a user has installed QGIS already, or has made such conversions already with other geospatial software.)

Step 3: Double click the main setup file to install DOS- and GUI-based Spectral Discovery for Landsat-8 Imagery

Step 4 (optional): Install free Google Earth Pro. Outputs in GeoTIFF format can be readily opened in Google Earth Pro.

Step 2: Install the most popular open-source GIS software QGIS. Spectral Discovery for Sentinel-2 Imagery will use the GDAL_translate.exe tool included in QGIS to convert downloaded Sentinel-2 data from compressed JPEG2000 format to uncompressed, analysis-ready GeoTIFF format. (Ignore this step if a user has installed QGIS already, or has made such conversions already with other geospatial software.)


Step 3: Double click the main setup file to install DOS- and GUI-based Spectral Discovery for Sentinel-2 Imagery

Step 4 (optional): Install free Google Earth Pro. Outputs in GeoTIFF format can be readily opened in Google Earth Pro.

Low-cost, full Perpetual Licences can be purchased via PayPal including pay option with a credit or debit card.

Users can easily perform band combinations, image stretching, image pan-sharpening, and exploratory image feature extraction with a few simple button clicks. All results (in GeoTIFF format) can be readily displayed in:

  • Google Earth Pro
  • GIS / remote sensing software, including open-source QGIS, ArcGIS, MapInfo, Global Mapper, ENVI, PCI, ERDAS IMAGINE and eCognition.
  • Consumer-level image display / editing software, including Windows Photo Viewer, PhotoShop

 

2: For the latest high-resolution commercial satellite & aerial imagery

We also offer advanced image analysis research and dedicated software development for the latest high-resolution satellite and aerial imagery. New, easy-to-use image fusion software tools are being developed for a wide range of image sources, including WorldView-4, WorldView-3, WorldView-2, Pléiades, SPOT 6 & 7, QuickBird, GeoEye-1, IKONOS, KOMPSAT-2, FORMOSAT-2, and ALOS. If you wish to learn more or to purchase dedicated / customised software tools, please email us.
