alignedGridStruct()

def python.tools.rasterfun.alignedGridStruct	(		file1,
			file2
	)

 Checks if two raster files can be aligned with their grids without need for resampling (with eps=0.001)

 :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:
