The wrspathrow supports working in R with the Worldwide Reference System
(WRS) 1 and WRS 2 grids used by NASA for cataloging Landsat scenes. The package
allows fetching the path and row numbers for a given spatial object, or
conversely, allows fetching a SpatialPolygonsDataFrame of the area covered by a
given path and row. The
wrspathrowData package (which
contains the WRS-1 and WRS-2 grids) is required by the wrspathrow package.
The easiest way to install the development version of the package is to
download it directly from GitHub (within R) using the
devtools package
by Hadley Wickham. After installing devtools from CRAN, type:
install_github('wrspathrow', username='azvoleff')at the R prompt to install wrspathrow.
