Abstract Unmanned aerial vehicle (UAV) based crop spraying has become a popular alternative in the field of precision agriculture. One key goals UAV is achieving spray coverage that as uniform possible to ensure maximum efficacy. Most existing studies literature focus on analysing effects parameters uniformity distribution using experimental studies. However, this work, we propose novel general...

Technology used in controlled environment facilities ranges from simple plastic row covers to sophisticated controlled and automated greenhouse and growth chambers. Crop models that estimate plant responses to climactic, nutritional, and other factors have been used to support controlled environment plant production at many of these technology levels. Such models typically consist of mathematic...

Evapotranspiration (ET) is important to hydrologists as well as regional planners. Methods for the calculation of ET require land use as well as weather and solar energy inputs. In this paper we present an ArcMap toolbar for the calculation of spatially distributed ET from ground based weather data. The toolbar provides functionality to interpolate weather data over the region of interest and c...
