RasterDataSources.jl

RasterDataSources downloads raster data for local use or for integration into other spatial data packages, like Rasters.jl. The collection is largely focussed on datasets relevant to ecology, but will have a lot of crossover with other sciences.

Currently sources include:

Source	URL	Status
CHELSA	https://chelsa-climate.org	BioClim, Future BioClim and Climate
WorldClim	https://www.worldclim.org	Climate, Weather, BioClim, and Elevation
EarthEnv	http://www.earthenv.org	LandCover and HabitatHeterogeneity
AWAP	http://www.bom.gov.au/jsp/awap/index.jsp	Complete
ALWB	http://www.bom.gov.au/water/landscape/	Complete
SRTM	https://www2.jpl.nasa.gov/srtm/	Complete
MODIS	https://modis.ornl.gov	Complete (beta)

Please open an issue if you need more datasets added, or (even better) open a pull request following the form of the other datasets where possible.

Retrieving data

Usage is generally via the getraster method - which will download the raster data source if it isn't available locally, or simply return the path/s of the raster file/s:

julia> using RasterDataSources

julia> getraster(WorldClim{Climate}, :wind; month=1:12)
12-element Array{String,1}:
 "/home/user/Data/WorldClim/Climate/wind/wc2.1_10m_wind_01.tif"
 "/home/user/Data/WorldClim/Climate/wind/wc2.1_10m_wind_02.tif"
 "/home/user/Data/WorldClim/Climate/wind/wc2.1_10m_wind_03.tif"
 "/home/user/Data/WorldClim/Climate/wind/wc2.1_10m_wind_04.tif"
 "/home/user/Data/WorldClim/Climate/wind/wc2.1_10m_wind_05.tif"
 "/home/user/Data/WorldClim/Climate/wind/wc2.1_10m_wind_06.tif"

 "/home/user/Data/WorldClim/Climate/wind/wc2.1_10m_wind_11.tif"
 "/home/user/Data/WorldClim/Climate/wind/wc2.1_10m_wind_12.tif"

Installation and setup

Install as usual with:

] add RasterDataSources

To download data you will need to specify a folder to put it in. You can do this by assigning the environment variable RASTERDATASOURCES_PATH:

ENV["RASTERDATASOURCES_PATH"] = "/home/user/Data/"

This can be put in your startup.jl file or the system environment.

RasterDataSources was based on code from the SimpleSDMDataSoures.jl package by Timothée Poisot.
