[pygeoapi] process: raster data output

[Francesco Bartoli]

Hi Martin,

as far as I can see from the specification this result example may apply to your case:
 "imagesOutput": [
   {
     "href": "https://www.someserver.com/ogcapi/Daraa/collections/Daraa_DTED/styles/Topographic/coverage?...",
     "type": "application/tiff; application=geotiff"
   },
   {
     "value": "VBORw0KGgoAAAANSUhEUgAABvwAAAa4CAYAAABMB35kAAABhGlDQ1BJQ0MgcHJvZmlsZQAA\nKJF9kT1Iw0AcxV9TpSL1A+xQxCFDdbIgKuKoVShChVArtOpgcumH0KQhSXFxFFwLDn4sVh1c\nnHV1cBUEwQ8QNzcnRRcp8X9JoUWMB8f9eHfvcfcOEOplplkdY4Cm22Y6mRCzuRUx9IogouhH\n ... \nj3Z5mX7/PCPVRJV92rpHK24xcJrzk20+tkeYlCPqcZNO3Lpni1OJWatPCcmgGDEqx7Om6lfa\nppM4k4BTe9+bsn3L9/9/yWhA0PwQGW8ipCZsnZt9lsdrYEM8z/M8z/M8z/M8z/M8z/MzLWY1\nAAAACUlEQVQ871H6P6JI+TxS5Wn2AAAAAElFTkSuQmCC",
     "encoding": "base64",
     "mediaType": "application/tiff; application=geotiff"
   }
 ],
so the `href` property could take the place of `url`.

If you want to host the geotiffs as resources under a new base location `data` there should be an extension developed on top of a cloned pygeoapi, or pygeoapi loaded and used as a library in a totally brand new python project with one of the supported and the most preferred framework for you.
It's then up to you how and where to store the actual geotiff files.

Hope this helps

Best,
Francesco
