Plot‐level satellite imagery can substitute for UAVs in assessing maize phenotypes across multistate field trials

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Maize plays a key role in agricultural profitability and food security on six continents. Successful efforts to breed higher‐yielding maize varieties depend on replicated yield trials in many environments. Capturing in‐season data can help improve and accelerate the development of regionally adapted hybrids, but collecting these data can be impractical

A MICRO-UAV WITH THE CAPABILITY OF DIRECT GEOREFERENCING [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2013
Abstract. This paper presents the development of a low cost UAV (Unmanned Aerial Vehicle) with the capability of direct georeferencing. The advantage of such system lies in its high maneuverability, operation flexibility as well as capability to acquire image data without the need of establishing ground control points (GCPs).

Extrinsic Parameter Calibration for Line Scanning Cameras on Ground Vehicles with Navigation Systems Using a Calibration Pattern

open access: yesSensors, 2017
Line scanning cameras, which capture only a single line of pixels, have been increasingly used in ground based mobile or robotic platforms. In applications where it is advantageous to directly georeference the camera data to world coordinates, an ...

A georeferenced implementation of weighted endemism [PDF]

open access: yesMethods in Ecology and Evolution, 2015
Summary Areas of endemism are conservation priorities and indicators of biogeographical processes, representing concentrations of range‐restricted biodiversity. While the term endemism describes geographical range restriction, the technical definition has often been re‐worked.
