R code for processing spectral data collected using a Unispec-DC instrument (PP systems) from the Arctic LTER long-term experimental plots. This code is written to streamline data processing, QAQC, preliminary analyses, and visualization and as such, organized into the following directories:
-
UnispecProtocol : process & quality check newly collected data, add to long term data set
-
UnispecRecord : standardize, process, and visualize long term data set
-
Visualizations : shiny application built to explore the ArcticLTER unispec record (2009-present)
-
Investigations : mainly code from 2019, with the following
- spectral_instrument_comparison: campaign to assess whether NDVI was the same across instruments for the Unispec-SC, Unispec-DC, ASD, RapidSCAN, and Greenseeker
- plot heterogeneity: comparing 5 or 10 measurements per plot
- seasonal trends:
- legacy "UnispecProtocol" scripts used for processing and quality checking the 2019 unispec data
User friendly scripts and summary documents currently under construction.
The end goal is for code to be operable by somehow with a little but not much experience of R. All code is written in R and utilizes the "tidyverse" packages. A good place to start for some background in R and good coding practices: R for Data Science.
