Description

Create a zonal file if it does not exist and calculate the zonal stats by calling the myZonal function. Modified from http://www.guru-gis.net/efficient-zonal-statistics-using-r-and-gdal/

Usage

ZonalPipe(ctryCode, admLevel, ctryPoly, nlType, configName, path.in.shp,
  path.in.r, path.out.r, path.out.shp, zone.attribute, nlStats,
  gadmVersion = pkgOptions("gadmVersion"),
  gadmPolyType = pkgOptions("gadmPolyType"), custPolyPath = NULL)

Arguments

ctryCode	the ctryCode of interest
admLevel	The country admin level of interest
ctryPoly	the SpatialPolygonsDataFrame country polygon to process
nlType	character The nlType of interest
configName	character the type of raster being processed
path.in.shp	The path to the country shapefile
path.in.r	The path to the raster tile
path.out.r	The path where to save the output zonal raster
path.out.shp	The path to save the output zonal shapefile (Ignored)
zone.attribute	The zonal attribute to calculate
nlStats	The stats to calculate
gadmVersion	The GADM version to use
gadmPolyType	The format of polygons to download from GADM
custPolyPath	Alternative to GADM. A path to a custom shapefile zip

Value

TRUE/FALSE
