Fertilization decisions depend on the measurement of a large set soil fertility indicators, usually through laboratory determination, which is costly and time-consuming. Visible near-infrared (vis-NIR) spectroscopy combined with machine learning can simultaneously predict various indicators. Spectroscopy inherently less accurate than direct determination. However, in many fertilization recommen...

The growing of marijuana (Cannabis sativa L.) on pubon measured leaf spectra and simulated canopy refleclic lands poses problems to the environment and the pubtance spectra, we would choose several relatively narrow lic. Remote sensing offers a potential way of monitoring (i.e., 30 nm or less) spectral bands in the green (550 nm), public lands for the production of marijuana. However, red (670 ...

The NASA airborne Thermal Infrared Multispectral Scanner (TIMS) was flown over Death Valley, California on both a daytime flight and a nighttime flight within a two-day period in July 1983. This Daedulus scanner has six channels in the thermal infrared, between 8 and 12 pm. Calibrated digital spectral radiance data from these flights, along with Landsat Thematic Mapper (TM) reflectance data, pe...

Mapping landscape variation in tree species richness (SR) is essential to the long term management and conservation of forest ecosystems. The current study examines the prospect of mapping field assessments of SR in a high-elevation, deciduous forest in northern Iran as a function of 16 biophysical variables representative of the area's unique physiography, including topography and coastal plac...
