TilesMaker: Tiles Maker Tool

In MBalthasar/SpatialDataToolbox: Toolbox for Spatial Data Manipulation

Description

This function divides the input file in tiles based on user preferences. The output data will be reprojected to UTM.

Usage

TilesMaker(user_file, user_aoi, diff_factor, length_factor, out_folder)

Arguments

user_file	A raster or sp objetct.
user_aoi	(optional) A sp object. Will be used to crop input data and create tiles.
diff_factor	Integer. Faktor after which the extent of the input file will be divided into x and y direction.
length_factor	Vector of two integer. Can be used instead of the diff_factor. Distance in meters of one tile n x and y direction.
out_folder	Character string. Path to which the output tiles and fishnet polygon should be written.

Value

A fishnet polygon in UTM projection.

Examples

library(sp)
library(raster)
library(rgdal)
library(geosphere)

# Load sample raster file
my_raster <- raster::brick(system.file(package = "SpatialDataToolbox", "extdata", "landsat_sample.tif"))

# Apply diff_factor
x1 <- TilesMaker(user_file = my_raster, diff_factor = 5, out_folder = "./")

# Delete created folder with tiles and fishnet polygon
unlink("./Fishnet", recursive = TRUE)

# Apply length_factor
x2 <- TilesMaker(user_file = my_raster, length_factor = c(10000,10000), out_folder = "./")
