Web24 aug. 2016 · Multispectral imagery: Enabling extrasensory perception One of the most extraordinary types of imagery collected by remote sensing is multispectral imagery. Each image is composed of data from a series of onboard sensors that collect small slices (or bands) across the electromagnetic spectrum. Web28 dec. 2024 · The use of multispectral imaging generates data and intelligence at a rate and level of accuracy that cannot be matched by traditional methods. Aside from the obvious advantage of drones being able to cover large areas much faster than surveyors, multispectral sensors can collect data which cannot be perceived by human senses.
Web22 apr. 2024 · Orthomosaics made from UAS collected multispectral imagery with bands in the visible red and near-infrared (NIR) range can be used to generate Normalized Difference Vegetation Index (NDVI) maps. NDVI calculations create a standardized index utilizing the amount of red light compared to NIR light reflected from a plant.
