Working With Raster Time Series Data in R
The tutorials in this series cover how to open, work with and plot raster time series data in R
. This series includes only the more-advanced, time-series
specific tutorials that are also part of the
Introduction to Working With Raster Data in R series.
Data used in this series cover NEON Harvard Forest and San Joaquin Experimental Range field sites and are in GeoTIFF and .csv formats.
Series Objectives
After completing the series you will:
-
Raster 05
- Understand the format of a time series raster dataset.
- Know how to work with time series rasters.
- Be able to efficiently import a set of rasters stored in a single directory.
- Be able to plot and explore time series raster data using the
plot()
function inR
.
-
Raster 06
- Be able to assign custom names to bands in a RasterStack for prettier plotting.
- Understand advanced plotting of rasters using the
rasterVis
package andlevelplot
.
-
Raster 07
- Be able to extract summary pixel values from a raster.
- Know how to save summary values to a .csv file.
- Be able to plot summary pixel values using
ggplot()
. - Have experience comparing NDVI values between two different sites.
Things You’ll Need To Complete This Series
Setup RStudio
To complete the tutorial series you will need an updated version of R
and,
preferably, RStudio installed on your computer.
R
is a programming language that specializes in statistical computing. It is a
powerful tool for exploratory data analysis. To interact with R
, we strongly
recommend
RStudio,
an interactive development environment (IDE).
