tabuleRaster: Fast tabulation of pixel values

In ecochange: Integrating Ecosystem Remote Sensing Products to Derive EBV Indicators

Fast tabulation of pixel values

Description

This function generates frequency tables for scenes in ecosystem remote sensing products by wrapping rasterDT. The function is mapped by gaugeIndicator to optimize computation of ecoystem extents.

Usage

tabuleRaster(layer = "", 
    del0 = TRUE, useNA = "no", 
    n256 = FALSE)

Arguments

layer	character. File path to an ERSP scene.
del0	logical. Remove the 0-count categories.
useNA	logical. Include NA values. This argument is passed to freqDT.
n256	logical. Do the raster contains less than 256 unique values?

Value

data.frame.
