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.
