In Rfssa: Functional Singular Spectrum Analysis

Load Montana Data from GitHub Repository

Description

This function loads the Montana dataset from a GitHub repository hosted at https://github.com/haghbinh/dataset/Rfssa_dataset. Hosting datasets on GitHub rather than including them in the Rfssa R package conserves storage space. The Montana dataset contains intraday hourly temperature curves measured in degrees Celsius and normalized difference vegetation index (NDVI) image data. Both types of data are recorded near Saint Mary, Montana, USA. The NDVI images cover a region located between longitudes of 113.30 degrees West and 113.56 degrees West and latitudes of 48.71 degrees North and 48.78 degrees North. For each recorded intraday temperature curve, an NDVI image was captured on the same day every 16 days, starting from January 1, 2008, and ending on September 30, 2013. The dataset is valuable for environmental analysis, especially in the context of studying the impact of temperature changes on vegetation. Combining both temperature and NDVI data can reveal more informative patterns and insights.

Usage

loadMontanaData()

Format

A list containing two components:

Temperature Data

A 24 by 133 matrix of discrete samplings of intraday hourly temperature curves.

NDVI Images

An array with dimensions 33 by 33 by 133, where each 33 by 33 slice represents an NDVI image.
