	)

Checks if two raster files can be aligned with their grids without need for resampling (with eps=0.001) Copied (more or less) from the opals C++ Code (with permission by gm) Author: lwiniwar Created: 03.03.2016 :param file1: input raster file 1 :param file2: input raster file 2 :return: True, if the grids of the files are aligned, False otherwise.

shell_gdal_rasterize()

def python.tools.rasterfun.shell_gdal_rasterize	(		shape,
			output_file,
			dim_file,
			tile_name = ""
	)

Rasterizes a shapefile/vector layer/vector geometry (polygons only) using the shell command "gdal_rasterize".

Needs to be in the path/working dir. :param shape: path to a shapefile / ogr Feature / ogr Geometry (polygon only) :param output_file: filename to write burned raster to :param dim_file: any tif that shows what areas to rasterize :param tile_name: string of the tile name :return:
