Plant breeding trials are extensive (100s to 1000s of plots) and are difficult and expensive to monitor by conventional means, especially where measurements are time-sensitive. For example, in a land-based measure of canopy temperature (hand-held infrared thermometer at two to 10 plots per minute), the atmospheric conditions may change greatly during the time of measurement. Such sensors measure small spot …
Precision Agriculture: Vegetation Spectral Indices with NIR Aerial Imagery
The examples below show various spectral index maps generated from the geo-referenced Orthomosaic at 4 cm per pixel Ground Sample Distance (GSD). NIR Geo-Referenced Orthomosaic
Pravia, LLC – NDVI Calibration
DroneMapper is very pleased to announce it has teamed with Pravia, LLC in generating geo-referenced and radiometrically corrected Normalized Difference Vegetation Index (NDVI) crop maps. NDVIs utilize the near infrared and visible bands to measure “green-ness” of a crop and can be used to identify crop stress. Not only will these maps be accurately geo-referenced but the radiometric correction will …
DN2K, LLC – MyAgCentral.com
DN2K operates a unique service called MyAgCentral (shown in the illustration), a subscription-based service for growers, retailers and service providers that offers precision agricultural data and integration to key software products for managing farms. Examples of data sets include heatmaps that graphically show key farming parameters such as: crop yield, fertilizer application, ground moisture, variable rate irrigation (VRI) and Normalized Difference Vegetation …
