auto_setup_dem: Setup the DEM mosaic for a given AOI
In azvoleff/teamlucc: TEAM land use and cover change data processing toolkit

Description Usage Arguments Details Value

This function will setup a set of DEM tiles for each Landsat path/row needed to cover a given AOI. The tiles can optionally be cropped to cover only the portion of each path/row that is included in the AOI, or can cover the full scene for each path/row needed to cover the AOI.

auto_setup_dem(aoi, output_path, dem_extents, of = "GTiff", ext = "tif",
  n_cpus = 1, overwrite = FALSE, crop_to_aoi = FALSE, notify = print,
  verbose = FALSE)

`aoi`	area of interest (AOI), as a `SpatialPolygonsDataFrame`, to use as as bounding box when selecting DEMs. Also used to crop and set projection of the output DEM(s) if `crop_to_aoi=TRUE`. Must be in a projected coordinate system.
`output_path`	the path to use for the output
`dem_extents`	a `SpatialPolygonsDataFrame` of the extents and filenames for a set of locally available DEM raster(s) that cover the `aoi`. See the `get_extent_polys` function for one means of generating this list. `dem_extents` must have a "filename" column.
`of`	output format to use when saving output rasters. See description of `of` in `gdalwarp`.
`ext`	file extension to use when saving output rasters (determines output file format). Should match file extension for output format chosen by `of`.
`n_cpus`	the number of CPUs to use for processes that can run in parallel
`overwrite`	whether to overwrite existing files (otherwise an error will be raised)
`crop_to_aoi`	whether to crop the dem to the supplied AOI, or to the Landsat path/row polygon for that particular path/row
`notify`	notifier to use (defaults to `print` function). See the `notifyR` package for one way of sending notifications from R. The `notify` function should accept a string as the only argument.
`verbose`	whether to print detailed status messages and timing information

This function uses gdalUtils, which requires a local GDAL installation. See http://trac.osgeo.org/gdal/wiki/DownloadingGdalBinaries or http://trac.osgeo.org/osgeo4w/ to download the appropriate installer for your operating system.
