Generate Global Tiling System

This function generates a matrix with bounding box information for a global tiling system (based on Lat/Lon).

Usage
genTile(
  tileSize = 1,
  offset = 0,
  StartNameFrom = c(0, 0),
  extent = list(xmin = -180, xmax = 180, ymin = -90, ymax = 90)
)
Arguments
tileSize

numeric, size of a single tile in degrees (EPSG:4326).

offset

numeric, shifts the tiling system in upper-left direction.

StartNameFrom

numeric. c(Lat-Direction,Lon-Direction) start number in the naming of the tiles.

extent

list. Tile system extent information, basically the coverage of the data on server.

Value

A matrix.

e3 <- genTile(tileSize = 5, StartNameFrom = c(1, 1), 
              extent = list(xmin = -180, xmax = 180, ymin = -60,ymax = 60)) 
head(e3)
