Data sets for the e-sensing project

SITS icon

This project contains in situ data sets used in the e-sensing project. These data sets consist of time series from selected locations, which are used to train machine learning models, and data cubes to run examples of sits usage.

To load these datasets, first, install the sitsdata package using devtools:

devtools::install_github("e-sensing/sitsdata")

Next, load it:

library(sitsdata)

In the next sections are examples of how you can use the datasets available.

In case of any issue in following the steps above, please check the installation tip section.

Data format

The sitsdata R package contains time-series to be used for classification with machine learning methods which are available when the package is loaded using library(sitsdata). All satellite image time-series have the following columns:

Installation tips

If you are having network issues installing the sitsdata package, please consider increasing the timeout limit:

options(timeout = 300) # Set timeout to 5 minutes

After updating the timeout limit, you can install the package using the devtools command:

devtools::install_github("e-sensing/sitsdata")

If you have any other issues, please ask for help in the issue section; we are keen to support you!
