Even, unfortunately no, this isn't the same. That is basically a saved array, but we have an advanced geospatial raster format that has become the standard almost R geospatial packages. It supports all the major things a geospatial raster should support, including georeferencing, pixel sizes, etc

GDAL Developers: How do I go about requesting a new driver? R's "raster" format is a pretty straightforward flat binary/header format (very similar to ENVI's). The specifications are laid out in: https://cran.r-project.org/web/packages/raster/vignettes/rasterfile.pdf I think this would be a ni

Re: [gdal-dev] Question: Creating overviews

Hi, That is normal. Overviews are kind of support files for the main image and geotransform can be stolen from there. With internal overviews in TIFF that's also the only possibility. If you need standalone downsampled images create them with gdal_translate or gdalwarp. -Jukka Rahkonen- Gane
