Overview

About

Maintained by Lampros MouselimisCRAN page ↗GitHub ↗Website ↗Issues ↗

Programmatic connection to the 'OpenAltimetry' API https://openaltimetry.earthdatacloud.nasa.gov/data/openapi/swagger-ui/index.html/ to download and process 'ATL03' (Global 'Geolocated' Photon Data), 'ATL06' (Land Ice Height), 'ATL07' (Sea Ice Height), 'ATL08' (Land and Vegetation Height), 'ATL10' (Sea Ice 'Freeboard'), 'ATL12' (Ocean Surface Height) and 'ATL13' (Inland Water Surface Height) 'ICESat-2' Altimeter Data. The user has the option to download the data by selecting a bounding box from a 1- or 5-degree grid globally utilizing a shiny application. The 'ICESat-2' mission collects 'altimetry' data of the Earth's surface. The sole instrument on 'ICESat-2' is the Advanced Topographic Laser Altimeter System (ATLAS) instrument that measures ice sheet elevation change and sea ice thickness, while also generating an estimate of global vegetation biomass. 'ICESat-2' continues the important observations of ice-sheet elevation change, sea-ice 'freeboard', and vegetation canopy height begun by 'ICESat' in 2003.

Changes in 1.1.0

Modified get_URL_data() to fail gracefully with an informative message (and return NULL) when the OpenAltimetry API is unavailable or returns a non-200 HTTP status, per CRAN policy for internet resources.
Updated tests/testthat/test-get_Atlas_data.R to reflect the changed upstream API behavior for atl03 queries without beamName (the API no longer errors). API-dependent tests now use skip_on_cran() and skip_if_offline().
Fixed vignettes/IceSat-2_Atlas_products_PDF.Rmd to build on machines without Chrome by adding screenshot.force = FALSE to the setup chunk, preventing knitr from attempting to screenshot htmlwidgets via webshot2/chromote.

Install

R (CRAN)pak (dev)Ubuntu (r2u)Fedora (COPR)openSUSE (OBS)

install.packages("IceSat2R", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("mlampros/IceSat2R")

Development version from mlampros/IceSat2R. Installs pak first if it is not already available.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-icesat2r

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-IceSat2R

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-IceSat2R

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed). We list this channel from recorded autoCRAN download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.
