Indirect Measurement

Indirect measurement is typically used in science to ascertain the size of something that can’t actually be measured in a directly quantifiable way. Thus, it is necessary to estimate the desired target size by measurement of a known object or area and extrapolate the unknown value from the known values directly measured. Learn More (Last

Fog Computing

The term, fog computing, was originated by Cisco. It is used to indicate the edge of an enterprise’s network. Fog computing has also been labeled as Fogging or Edge Computing. The concept is intended to describe the computing nodes available between a host device and the cloud. Therefore, it is considered to be a decentralized

Phenology

Phenology is the study of occurrences as in recording items associated with natural events and dates of recurrent events. These recording reflect their relationship to the climatic seasonal changes as well as environmental factors such as: Temperature, pH of the water/soil, and amount of sun. Basically, phenology uses a combination of ecology and meteorology. Britannica.com

Soil Line

The soil line, in reference to remote sensing analyses, is a plot line of digital number values that typically fall 45° along this line. These values represent red light wavelengths against very-near infrared light (NIR) wavelengths. Generally, soil values fall close to the plot line and vegetation fall away from it. Thus, the vegetation plotting

SAVI (Soil Adjusted Vegetation Index)

Soil Adjusted Vegetation Index is sort of a hybrid between ratio-based indices and perpendicular indices. This index recognizes that the isovegetation lines do not run along side one another nor do they necessarily converge to a single point. It is a way to correct for the impact of soil line disparities on two-band vegetation indices

NDRE (Normalized Difference Red Edge) Index

The NDRE (Normalized Difference Red Edge Index) is used to measure the light waves (approximately the 715 nm range of the spectrum) that are collected from multispectral image sensors. The images are processed and analyzed to determine how healthy the target crop and field is. It is very similar to the NDVI vegetation index it

(ENDVI)Enhanced Normalized Difference Vegetation Index

ENDVI uses blue and green visible light  instead of solely using red light. This index singles out plant health indicators better because it shows how the plant’s surface absorbs the blue light in contrast to the reflected green light and the NIR light, thus it generates a more reliable sign of the crop’s health. The
