R functions for downloading, extracting, and plotting climatological data as a function of user supplied multi and single geospatial polygon and point data.
If you are a scientist seeking a convenient solution for downloading, extracting , and plotting climatological data, consider exploring the features of this package. It grants you access to three widely recognised modelled data sets, namely WorldClim 2, CHELSA, and NASA’s SRTM. It seamlessly handles both multi and single geospatial polygon and point data, allowing you to extract outputs that can serve as covariates in various ecological studies. It also allows you to visualise these extractions using two common graphic options – the Walter-Lieth climate diagram and the Holdridge life zone classification scheme. The last option is a scheme of our own design which incorporates aspects of both Walter-Leigh and Holdridge. The package’s user-friendly access and extraction of globally recognisable data sets significantly enhance its versatility and usability across a broad spectrum of applications.
For any questions, comments or bug reports please submit an issue here on GitHub. Suggestions, ideas and references of new algorithms are always welcome.
You can install the development version from GitHub with:
# install.packages("devtools")
devtools::install_github("jamestsakalos/climenv", build_vignettes = TRUE)
This is a basic example which shows you how to use the main climenv
function:
library(climenv)
# Step 1. Import the Sibillini National Park Boundary
# Step 2. Run the download function
# Step 3. Run the extract function
#* See ce_download & ce_extract documentation
# Steps 1, 2 & 3 can be skipped by loading the extracted data
data("it_data")
# Step 4. Visualise the climatic envelope using a Holdridge diagram
p1 <- plot_h(data = it_data, "MED")
The package vignette provides detailed explanation and demonstration on the use of climenv.
