How to download SRTM and worldclim in R?
With the function getData () you can download the following data directly into R and process it: 1 SRTM 90 (elevation data with 90m resolution between latitude -60 and 60) 2 World Climate Data (Tmin, Tmax, Precip, BioClim) 3 Global adm. boundaries (different levels) More
How to download SRTM for an entire country?
Select Dataset: The first argument specifies the dataset. ‘SRTM’ returns the SRTM 90 elevation data. Specify Lon: The second argument specifies the lon of the SRTM tile. Specify Lat: The second argument specifies the lat of the SRTM tile.
How to acquire data about global AMD boundaries?
To be able to use the getData () function to acquire data about global amd. boundaries we have to specify three arguments: Select Dataset: The first argument specifies the dataset. ‘GADM’ returns the global administrative boundaries.
How to extract data from worldclim using R?
I create random points as example, in your case use coordinates to create a SpatialPoint object. Finally, use extract. With cbind.data.frame and coordinates you will get the desire data.frame. I used random points, so I got a lot of NA.
How to get data from worldclim using raster?
You can use raster package to download WorldClim data, see ?getdata to know about resolution, variables and coordinates. I create random points as example, in your case use coordinates to create a SpatialPoint object.
What do I need to know about dataretrieval?
Returns time-series data summarized to a day. Default is mean daily. Groundwater levels. Surface water measurements. Metadata information for one or many parameter codes. Annual maximum instantaneous streamflows and gage heights. Discrete water quality data.

How is Cru data stored in worldclim data?
Both datasets are based on weather station data. WorldClim data is also stored in a different file format. You might remember that CRU data came as NetCDF files, which are basically large data arrays. WorldClim data on the other hand can be download as GeoTiff files.
