frg_extract_svi: frg_extract_svi

In lbusett/frgtool: Analyze Post Fire Vegetation Regeneration from Time Series of Summertime MODIS data

Description

Function used to extract Scaled VIs time series of the different pixels of analyzed burnt areas, associate info form the burnt areas shapefile and save as an RData file to be used for statistical analysis

Usage

frg_extract_svi(SVI_file, shape_file, out_file, overlap, shape_file_orig,
  lut_file_multiple, opts, force_update)

Arguments

SVI_file	string ENVI Meta File associated to time serie to be analyzed
shape_file	string Burnt Areas Shapefile (Must Correspond to the 'burned_once' shafile if overlap == 'Single' Must Correspond to the 'burned_multiple' shapefile if overlap == 'Multiple')
out_file	base path for the output files
overlap	string If == 'Single', extract time series for areas burned once. if =='Multiple', extract time series for areas burned multiple times
shape_file_orig	string Filename of the original input BAs shapefile
lut_file_multiple	string Filenlame of the LUT table created by FRG_Process_Shapefile.py
opts	list of options passed from frg_fullprocessing()
force_update	logical If TRUE, recreate the ROI file even if it already exist, default: FALSE

Details

This function is used to extract Scaled VIs time series of the different pixels of analyzed burnt areas from the raster images created by 'FRG_Compute_SVI.R“, associate ancillary info derived form the burnt areas shapefile (e.g., Area, FireYear, ...) and save results as an RData file (in the '/TS_Extraction subfolder) to be used later for statistical analysis

Value

'DONE' if all went OK, otherwise error message
