False-color images demonstrate remote sensing applications in precision farming. [1] Yara N-Sensor ALS mounted on a tractor's canopy – a system that records light reflection of crops, calculates fertilisation recommendations and then varies the amount of fertilizer spread Precision Agriculture NDVI 4 cm / pixel GSD
Remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object, ... For agricultural statistics, field ...
Heather McNairn, is a federal research scientist at the Ottawa Research and Development Centre, Agriculture and Agri-Food Canada. [1] She specializes in remote sensing technology, and her research focuses on the use of Synthetic Aperture Radar satellites (SARs) to monitor the condition of crops and soils. [2] [3]
Hyperspectral remote sensing is used in a wide array of applications. ... Another application in agriculture is the detection of animal proteins in compound feeds to ...
The normalized difference red edge index (NDRE) is a metric that can be used to analyse whether images obtained from multi-spectral image sensors contain healthy vegetation or not. [1]
Remote sensing has since been used to monitor natural disasters, study climate changes and monitor air pollution. [1] Over the course of her career, Ustin made use of remote sensing data from five different continents, including tracking the impacts of agriculture on forests and monitoring invasive plant species.
2011 Enhanced vegetation index based on MODIS Terra data. The enhanced vegetation index (EVI) is an 'optimized' vegetation index designed to enhance the vegetation signal with improved sensitivity in high biomass regions and improved vegetation monitoring through a de-coupling of the canopy background signal and a reduction in atmosphere influences.
She also developed biophysical descriptors and procedures for assimilating remote-sensing data to derive yield estimates and determine site-specific agricultural management practices. [3] She was an active participant in The Boreal Ecosystem – Atmosphere Study (BOREAS), and she measured the fluxes of carbon dioxide, methane, and isoprene in ...
