Ground Truthing Systems

• A portable system ideal for Ground Truth Validation Campaigns
• Automatic calculation of different vegetation indices, eg NDVI, PRI, LAI, etc.
• Results can be viewed on the display, stored and/or logged
• Choice of sensors types depending on application
• Standard NDVI & PRI wavelengths or your choice
• Wavelengths can be matched to one of the Earth Orbiting Satellites, eg MODIS
• Sensors are individually calibrated and supplied with a calibration certificate
• Calibration is traceable to the UK’s national standard, NPL
• GPS location stored with sensor readings

The following systems incorporate the satellites which we are most asked for.  However, we can usually match the wavebands of other Earth Orbiting Satellites – please ask.  We can also provide systems using other wavebands – again please ask
