With the deployment of a number of different remote sensing platforms yielding imagery of varying resolution and bandwidth, Cyberland gives you the ability to quickly and accurately fuse disparate remotely sensed imagery. This fast and easy fusion of multi-temporal and multi-band imagery into a single data product is accomplished using tried and proven image matching techniques developed at Supresoft.

CyberLand makes full use of the spectral information contained in high resolution, panchromatic SPOT imagery and multi-spectral TM imagery.

Applications for CyberLand are many and varied and include:

• map updates
• land planning
• resource analysis
• disaster management, etc.
  

Main Functions

CyberLand has been designed for the fast and accurate matching, fusing and rectifying of various remotely sensed images.

Homologous points are matched quickly and accurately:

• CyberLand can rapidly identify a dense, evenly distributed and accurate field of homologous points in two images of the same area. The matching routines can easily find 10,000 to 100,000 homologous points in a matter of seconds. By the differential rectification of small surface elements, CyberLand successfully avoids problems such as image blur, often caused by the poor superimposition of fused images (especially prevalent in mountainous areas)
  
• Image rectification is performed efficiently and accurately:
  
• Differing rectification techniques are utilized for different kinds of imagery
  
• For SPOT imagery, precise rectification needs only 5-8 control points within the DRG and the root mean square error (RMSE) of the eventual orthoimage is less than 1.5 pixels
  
  

Powerful visualization:

• Superimposition of various spatial data sets such as Digital Orthorectified Maps (DOM), Digital Raster Graphics (DRG) and Digital Elevation Models (DEM) etc.
  
• Dynamic, real-time adjustment for each layer's transparency
  
• Concurrent, real-time processing of a number of images
  
• The provision of various tools in the viewer for superimposition, estimation and distance measurement, etc.
  
  

User friendly interface:

• CyberLand has uniform interfaces and simple wizards for many complex functions

CyberLand provides two methods to check planimetric accuracy for rectified imagery:

• Superimpose different images and DRG to visually check the planimetric accuracy directly, or by quantitatively measuring the offset between two layers
  
• Checking the RMSE of corresponding points in the rectified images and the reference data (e.g. Orthoimage, DRG, Control Points.)
