Ground truthing

The collection of ground-truth data on location enables calibration of remote-sensing data, and aids in the interpretation and analysis of what is being sensed.

The field collection of reflectance spectra of in place materials is essential for interpreting unknown materials in multi-spectral and hyperspectral remote sensing data, and validating sensor performance.

In the realm of earth observation and as satellite imagery and remote sensing become more popular, it can still be confusing to determine how to use or interpret imagery to solve real problems.
When is an image not just an image?
If you think about the photos you take with a camera, what you see is what you get. A color photo combines red, green and blue reflected light in the same way that our eyes capture reflected light, so it looks like a realistic version of what we would see if …

The ASD FieldSpec 4 Hi-Res NG provides enhanced spectral resolution to support accurate calibration and image classification analysis.
Higher resolution hyperspectral sensors yield greater precision for remote sensing classification applications, producing more information from every pixel generated in an image than ever before. In order to take advantage of the full potential of these sensors, measurements from ground-based instrumentation need to meet or exceed the sensor’s spectral resolution. In the absence of this resolution equality, data are interpolated during post-processing; as a result, vital spectral information can be smoothed and lost.
The enhanced spectral resolution …
