gdalR package

This is a repo for package that contains a collection of functions that call GDAL externally on the milkun cluster.

To install the package, run:

devtools::install_github("mirzacengic/gdalR")

NOTE: Functions are not that general. They're designed to work on milkun cluster (Linux), but can be adapted to be more generalized. Requires GDAL installed.

Working list of functions utilized right now

• GDAL_LC_tile() - split, process, and merge rasters in parallel.
• GDAL_algebra() - raster algebra.
• GDAL_aspect() - calculate aspect from DEM.
• GDAL_crop() - crop raster with shapefile. Only this function has some documentation.
• GDAL_mosaic_tile() - lower level function that merges back tiled raster from GDAL_LC_tile.
• GDAL_reproject() - reproject raster.
• GDAL_resample() - resample raster.
• GDAL_slope() - calculate slope from DEM.
• GDAL_get_changes() - extract changes from two raster from different timesteps with gdal_calc.py. Needs debugging!
• GDAL_raster_to_polygon() - convert raster to a polygon (ESRI Shapefile) using gdal_polygonize.py.
