Determine which raster tiles to download for topographic variables

Given a bounding box, defining the spatial extent of the study area, return a list of tiles names which need to be downloaded to cover this area.

Usage

tileSelector(bound)

Arguments

bound

Data frame. 'x' and 'y' coordinates of the extent for which the BL instance will cover.

Examples

if (FALSE) { # \dontrun{
bound <- data.frame(
  y = c(30.1, 30.1, 49.5, 49.5, 30.1),
  x = c(-126, -82, -82, -126, -126)
)

bound <- data.frame(
  y = c(15, 50, 75, 44, 15),
  x = c(-63, -64, -180, -180, -180)
)

tileSelector(bound)
} # }
