Qualitative Measurement

The process of obtaining and interpreting thermal images based on thermal images based on thermal contrast in order to identify areas that correlate to construction or sub-surface anomalies; the purpose is more to determine where a temperature difference exists than to obtain a number for the temperature difference or the actual temperature.

Quantitative Measurement

The process of obtaining thermal images with correct temperature readings. Especially useful in situations when the exact temperature or temperature difference of the target determines whether it falls in or out of a determined criteria or range of acceptability.
