aggHRUTableToHUC10: Aggregate HRU Table to HUC-10

In ssaxe-usgs/METsteps: Aggregate Data to the HUC 2-10 Levels (one line, title case)

Description

This function aggregates HRU values in table format to HUC-10 values. It produces the same list output as the aggregateRasterToPolygons() function and output can be fed directly into the downscaleHUC10 function.

Usage

aggHRUTableToHUC10(HRUfolder, dataName, dataCategory, startDate = "auto",
  timeStep = "day", ext = "csv", sep = "auto", header = TRUE,
  dateColumn = 1, sortNames = T, verbose = T)

Arguments

HRUfolder	Character, required; Path to folder containing HRU region files. Files should be in order by region from r01 to r18.
dataName	Character, required; Name of gridded dataset.
dataCategory	Character, required; Type of dataset ('precip', 'AET', 'SWE', etc).
startDate	Character, optional; Starting date of rasters in format "YYYY-MM-DD". DD required but irrelevant if not daily rasters. Defaults to "auto". PRMS files should include a date column in each table. If startDate is set to "auto", identify the date column by number if it is different than 1.
timeStep	Character, required; Time step between layers. Options are 'day', 'week', 'month', 'quarter', and 'year'. Defaults to day.
ext	Character, optional; File extension. Defaults to 'csv'.
sep	Character, optional; Field seperator character. Defaults to 'auto'.
header	Logical, optional; Do files have headers? Defaults to TRUE.
dateColumn	Integer, required; If startDate == "auto", which column in the tables contains the dates?
sortNames	Logical, optional; Should files names be sorted alphabetically? Defaults to TRUE.
verbose	Logical, optional; Should progress updates be printed to console?
dataExtension	Character, required; Gridded file extension to import, must be compatible with 'raster' package (tif', 'nc', ect). The .grd format is discouraged due to connection issues that occur during processing.

Value

Table of mean raster values for each gridded dataset layer. Columns are gridded layers, rows are shapefile features.

Examples

aggHRUTableToHUC10(HRUfolder    = "C:/Path/To/PRMS/Folder",
                   dataName     = "PRMS",
                   dataCategory = "Recharge")
