getSpatialTiles: Get a list of tiles (regular blocks)
Description
Creates a list of tiles ("SpatialPolygons") for a given spatial domain i.e. extent.Usage
## S3 method for class 'Spatial':
getSpatialTiles(obj, block.x, block.y = block.x,
overlap.percent = 0, limit.bbox = TRUE, return.SpatialPolygons = TRUE)Arguments
obj
object of class "Spatial*"
block.x
numeric; size of block in x-direction (meters or corresponding mapping units)
block.y
numeric; size of block in y-direction (meters or corresponding mapping units)
overlap.percent
numeric; percentage overlap (must be a positive number)
limit.bbox
logical; specifies whether to limit the extent of tiles to the bounding box only
return.SpatialPolygons
logical; specifies whether to return a list of tiles as "SpatialPolygons" or a data frame with bounding box coordinates
Value
- Returns a list of tiles either as a list of
"SpatialPolygons" or a data frame with with bounding box coordinates.
Details
The first output tile starts by default at the lower left corner. getSpatialTiles-method can only be used to generate regular tiles.See Also
