Abstract: Non-transitory computer-readable media, spectroradiometer systems, and methods for calibrating a spectroradiometer. In one embodiment, a non-transitory computer-readable medium includes instructions that, when executed by an electronic processor, cause the electronic processor to perform a set of operations. The set of operations includes receiving spectral data regarding an object-of-interest that is captured by a handheld spectroradiometer, detecting a characteristic of the object-of-interest by performing a spectral analysis on the spectral data that is received, and controlling a display to display the characteristic of the object-of-interest.

Abstract: A simple, effective and inexpensive water-quality measurement system comprises a housing suitable for travel on or in a body of water; one or more sensors for measuring water properties as the housing travels; a memory for storing information relating to the measured water properties; and software for processing measured properties. This invention combines into a single, inexpensive, and comprehensive system the sensors, computer hardware, signal-processing, Geographic Information System data, and Decision Support Software. This integration yields a system of novel and unparalleled utility. The water properties measured by the system may include: water temperature, water conductivity, pH level, dissolved oxygen, turbidity, water depth, salinity, total dissolved solids (TDS), ORP, chlorides, nitrates, and phosphates.
