In HunterGleason/R.ccdc.tools: Simple Tools for Processing Zhu & Woodcock 2014 CCDC Outputs

Function for plotting surface reflectance curves by category (i.e., output of 'sample_ccdc_by_catg').

Description

Function for plotting surface reflectance curves by category (i.e., output of 'sample_ccdc_by_catg').

Usage

plot_ccdc_by_catg(
  ccdc_img_at_pnts,
  ccdc_img_date,
  catg_field,
  band,
  days = 730,
  med_only = F,
  ylim = c(0, 1)
)

Arguments

ccdc_img_at_pnts	(data.frame) A data.frame containing the categories of interest, and associated CCDC coefficients for a given date (i.e., output of 'sample_ccdc_by_catg')
ccdc_img_date	(character) A representation of the CCDC image date that can be interpreted by as.Date()
catg_field	(character) Name of the column indicating the categories of interest.
band	(character) The name of the band for which to forecast CCDC surface reflectance time series. One of 'blue', 'green', 'red' 'nir', 'swir1','swir2' or 'therm'.
days	(integer) Number of days to predict surface reflectance from the CCDC image data ('ccdc_img_date').
med_only	(boolean) When true, only median surface reflectance values are plotted by category
ylim	(numeric) Vector of length 2 defining the Y-Axis limits, defaults to c(0,1)

Value

(List) A data.frame with all data used for plot generation ('srdata'), a 'ggplot' object ('srplot'), and a data.frame with the legend codes cross-walk ('crosswalk').
