ABOUT DATA FUSION

• Geophysical Data are color-coded as follows

• The integration of remotely sensed data is simply
  a form of compositing, where multiple data sets
  are unified into a single image that carries most
  or all of the information. It is accomplished
  by
• Simple arithmetic operations (e. g. adding
  images together)
• Computer Graphical overlays (e. g.
  translucencies)
• Statistical correlation (e. g. PCA)
• Incorporating Spatial Context (e. g. artificial
  intelligence)
• Theory (e. g. deductive reasoning)

House detail

• All Geophysical Data are displayed with 20-meter
  grid lines, and have sub-meter resolution.
• All Multi-spectral and Pan-Chromatic Data are
  from the QuickBird satellite.

• Principle Components Analysis
• GPR, magnetometry, conductivity, and magnetic
  susceptibility images were subjected to a
  principle components.analysis. The first three
  components are colored blue, green and red.
• Components 1-3 are combined in an RGB color
  composite.
