UAStools is a package developed to provide useful tools for working with remote sensing data set, specifically in reference to field-based, agriculture research plots. Currently, the plotshpcreate.R function is available to construct a multi-polygon shapefile (.shp) of a reasearch trial, with individual polygons defining specific research plot. A full video tutorial is availible with accompanied script.
Make sure you have the latest version of R.
R/UAStools is availible on GitHub.
You then need to install the devtools package, plus a set of package dependencies: sp and rgdal. (Additional, secondary dependencies will also be installed.)
To install R/UAStools execute the following commands in R:
install.packages("devtools")
library("devtools")
devtools::install_github("andersst91/UAStools")
library("UAStools")
