How to convert HDF4 files to GeoTIFFs in R?
Basically gdal_translate from the gdalUtils package is the saving grace for anyone who wants to use hdf4 files in R. It converts hdf4 files into geoTIFFs without reading them into R.
How is data stored in a GeoTIFF file?
When you work with geotiff s the spatial information that describes the raster data are embedded within the file itself. Data note: Your camera uses embedded tags to store information about pictures that you take including the camera make and model, and the time the image was taken.
What’s the difference between a GeoTIFF and a tag?
What is a GeoTIFF?? A GeoTIFF is a standard .tif or image file format that includes additional spatial (georeferencing) information embedded in the .tif file as tags. These are called embedded tags, tif tags. These tags can include the following raster metadata:
How to read MODIS 17 data files into R?
I’m trying to read MODIS 17 data files into R, manipulate them (cropping etc.) and then save them as geoTIFF’s. The data files come in .hdf format and there doesn’t seem to be an easy way to read them into R. Compared to other topics there isn’t a lot of advice out there and most of it is several years old.
Is there a way to read HDF files into R?
The data files come in .hdf format and there doesn’t seem to be an easy way to read them into R. Compared to other topics there isn’t a lot of advice out there and most of it is several years old. Some of it also advises using additional programmes but I want to stick with just using R.
Can a HDF file be converted to rgdal?
R doesn’t do hdf4 files and pretty much all the packages (like rgdal) only support hdf5 files. There are a few posts about downloading drivers and compiling rgdal from source but it all seemed rather complicated and the posts were for MAC or Unix and I’m using Windows.

Can you read a.tif file into R?
Now you can read your .tif files into R using, for example, raster from the raster package and work as normal. I’ve checked the resulting files against a few I converted manually using QGIS and they match so I’m confident the code is doing what I think it is.
