modisfast (formerly opendapr) is an R package that provides functions to speed-up the download of time-series raster data products derived from MODIS and VIIRS observations, as well as other widely-used satellite-derived environmental data (e.g. Global Precipitation Measurement Mission).

modisfast uses the abilities offered by the OPeNDAP framework (Open-source Project for a Network Data Access Protocol) to download a subset of Earth science data cube, along spatial, temporal or any other data dimension (depth, …). This way, it reduces downloading time and disk usage to their minimum : no more 1° x 1° MODIS tiles when your region of interest is only 100 km x 100 km wide ! Moreover, modisfast supports parallelized downloads.

modisfast is hence particularly suited for retrieving MODIS or VIIRS data over long time series and over areas, rather than short time series and points.

Below is a comparison of modisfast with other packages available for downloading chunks of remote sensing data :

Package Data Temporal subsetting* Spatial subsetting* Dimensional subsetting*
modisfast MODIS, VIIRS, GPM
MODIS MODIS
MODIStsp MODIS
MODISTools MODIS and VIIRS (but not all collections)
appeears MODIS, VIIRS, and many others

* at the downloading phase

Installation

The package can be installed with:

if(!require(devtools)){install.package("devtools")}
devtools::install_github("ptaconet/modisfast")
library(modisfast)

Work is ongoing to publish the package on the CRAN.

Get Started

Accessing and opening MODIS data with modisfast is a simple 3-steps workflow, as shown in the example below.

First, define the variables of interest (including ROI, time frame, collection, and bands) :

# Load the packages
library(modisfast)
library(sf)
library(terra)

# ROI and time range of interest
roi <- st_as_sf(data.frame(id = "any_name", geom = "POLYGON ((-5.82 9.54, -5.42 9.55, -5.41 8.84, -5.81 8.84, -5.82 9.54))"), wkt="geom", crs = 4326) # a ROI of interest, format sf polygon
time_range <- as.Date(c("2017-01-01","2017-06-01"))  # a time range of interest

# MODIS collections and variables (bands) of interest
collection <- "MOD11A2.061"  # run mf_list_collections() for an exhaustive list of collections available
variables <- c("LST_Day_1km","LST_Night_1km","QC_Day","QC_Night") # run mf_list_variables("MOD11A2.061") for an exhaustive list of variables available for the collection "MOD11A1.062"

Then, with modisfast, get the OPeNDAP URL of the data and download them :

## Login to Earthdata servers with your EOSDIS credentials. 
# To create an account (free) go to : https://urs.earthdata.nasa.gov/.
log <- mf_login(credentials = c("username","password"))

## Get the URLs of the data 
urls <- mf_get_url(
  collection = collection,
  variables = variables,
  roi = roi,
  time_range = time_range
 )

## Download the data. By default the data is downloaded in a temporary directory, but you can specify a folder
res_dl <- mf_download_data(urls)

And finally, open the data in R as a terra::SpatRaster object using the function mf_import_data() (see here why you should use this function, instead of the original terra::rast(), in the context of modisfast) :

r <- mf_import_data(
  path = dirname(res_dl$destfile[1]),
  collection_source = "MODIS"
  )

terra::plot(r)

et voilà !

modisfast is particularly suited for retrieving MODIS or VIIRS data over long time series and over areas, rather than short time series and points.

There are other R packages available for accessing MODIS data, which may be more suitable if your requirements differ. These include :

Next steps

Next developments may involve including access to more collections from other OPeNDAP servers.

Any contribution is welcome !

Acknowledgments

We thank NASA and its partners for making all their Earth science data freely available, and implementing open data access protocols such as OPeNDAP. modisfast heavily builds on top of the OPeNDAP, so we thank the non-profit OPeNDAP, Inc. for developing the eponym tool in an open and collaborative way.

We also thank the contributors that have tested the package, reviewed the documentation and brought valuable feedbacks to improve the package : Florian de Boissieu, Julien Taconet, Nicolas Moiroux

The initial development and first release of this package were financed by the MIVEGEC unit of the French Research Institute for Sustainable Development, as part of the REACT project.

By enabling to download subsets of data cubes, modisfast facilites the access to Earth science data for R users in places where internet connection is slow or expensive and promotes digital sobriety for our research work.

The OPeNDAP, over which the package builds, is a project developed by the non-profit OPeNDAP, Inc. and advanced openly and collaboratively. By using this data access protocol, modisfast support the open-source-software movement.
