Support raster geoinformation

Using raster georeferenced files is a popular way of storing geoinformation in many disciplines. Many open data repositories (e.g. Copernicus Climate Data Store, NASA Earth Data) provide raster files. GeoTiff, NetCDF are some of the most popular formats. GDAL subprograms allow for easy conversion between formats and extraction of relevant metadata (e.g., with gdalinfo). I know this has been discussed before, but still, I think raster support would be a nice feature and could increase the popularity of frictionless in some fields. Is there any interest in this? Is someone already working on it?

I have started working on a raster dataflow here: https://github.com/enermaps/dataflows/tree/raster See README-raster.md for more information

I can confirm what @gperonato has mentioned. During our H2020 project Hotmaps we were searching for guidelines to create metadata for raster data, which later on could help us in integrating the datasets in the database. We encountered with the frictionless guidelines; however, no guidelines were provided for raster data. As a result, we tried to define and create own guidelines for the raster data (for details please refer to page 11-13 of this document). A sample of datapackage that was developed for raster file can be found HERE. As mentioned in the previous comment by @gperonato , it is pretty easy to obtain encapsulated metadata of raster file using GDAL library and subsequently, create a datapackage file for it.

I would be happy to collaborate on this topic, if required.
