Sentence examples for the ground plot from inspiring English sources

LiDAR metrics were extracted for up to four 0.06 ha circular cells spaced at 1 km intervals either side of the ground plot and another cell over the ground location.

We recorded 'nonforest' if the ground plot was dominated by nonforest land use with none of the vegetation types present.

The values for each predictor variable were assigned to ground plots, based on proximity of the ground plot center to the nearest pixel center for each predictor variable.

We accomplished this using a bootstrap method involving resampling n samples from the ground plot data with replacement using equal probability sampling, following recommendations from McRoberts et al. (2011) and based on work by Efron and Tibshirani (1986).

To account for spatial heterogeneity due to stand structure and topography, the methodology developed by Ferster et al. (2011) was applied to the ground plot data at the flux tower sites.

First, they did not include other commonly used vegetation indices (i.e., NDMI, NBR) or texture variables (i.e. standard deviation in a 3 × 3 window around the ground plot), which we found to be useful in our study, as have others (e.g., Lu et al. 2014).

Two sets of models are employed to relate satellite measurements to the ground plots.

The flight lines were spaced 5 km apart and were distributed over the ground plots.

In this paper two aspects of ground reference data collection were analyzed: (1) the positioning error of the ground plots; and (2) the optimal number of training plots.

An airborne laser system (ALS) is used as an intermediary to tie the GLAS measurements of forest height to a small subset of US Forest Service USFSS) ground plots by flying the ALS over the ground plots and, independently, over individual GLAS footprints.

Construction of the maps typically entails, in part, rectifying the satellite images to a geographic coordinate system, observing ground plots whose coordinates are obtained from Global Positioning System (GPS) receivers that are calibrated to the same geographic coordinate system, and then matching ground plots to image pixels containing the centers of the ground plots.
