getSpatialTiles: Get a list of tiles (regular blocks)

In GSIF: Global Soil Information Facilities

Description

Creates a list of tiles ("SpatialPolygons") for a given spatial domain i.e. extent. Input can be any object of class "Spatial" or "GDALobj".

Usage

## S4 method for signature 'Spatial'
getSpatialTiles(obj, block.x, block.y = block.x, 
    overlap.percent = 0, limit.bbox = TRUE, return.SpatialPolygons = TRUE)
## S4 method for signature 'ANY'
getSpatialTiles(obj, block.x, block.y = block.x, 
    overlap.percent = 0, limit.bbox = TRUE, return.SpatialPolygons = FALSE)

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

Details

The first output tile starts by default at the lower left corner. getSpatialTiles-method can only be used to generate regular tiles.

Value

Returns a list of tiles either as a list of "SpatialPolygons" or a data frame with with bounding box coordinates.
