Data sets for the e-sensing project
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:
longitude(East-west coordinate of the time series sample in WGS
84).latitude(North-south coordinate of the time series sample in WGS
84).start_date(initial date of the time series).end_date(final date of the time series).label(the class label associated to the sample).cube(the name of the image data cube associated with the data).time_series(list with the values of the time series).
