Serializing to RasterField()

See original GitHub issue

Hello django-rest-framework-gis team, thanks for your work on this package, it’s been super helpful for me recently. I have a quick question that I’m hoping someone can help me with. I have read through the ReadMe and also searched issues, but I can’t see a mention of ‘raster’ so I hope it’s okay to post a quick question here.

** Question** Is it possible to easily serialize a raster (.tif) image so that it can be saved to a geodjango RasterField()?

Use Case I have an app which grabs some Corine landcover data via the API. With the .tif file in memory, I wish to save the data to a RasterField:

# bbox = <add_bbox_coords_here>
corine_lc = requests.get("https://image.discomap.eea.europa.eu/arcgis/rest/services/Corine/CLC2018_WM/MapServer/export?bbox="+bbox+"&bboxSR=4326&layers=&layerDefs=&size=800%2C800&imageSR=&historicMoment=&format=tif&transparent=true&dpi=300&time=&layerTimeOptions=&dynamicLayers=&gdbVersion=&mapScale=&rotation=&datumTransformations=&layerParameterValues=&mapRangeValues=&layerRangeValues=&clipping=&spatialFilter=&f=json")
corine_lc = corine_lc.json()
file = rasterio.open(corine_lc['href'])

# Use 'file' to save to a RasterField

If this is a ridiculous way to approach the problem, does anyone know a better way of doing this? Perhaps some sort of ByteIO way, saving the .tif as raw data into a different model field type?

Thanks!

I honestly have no idea, nor I know if this is on-topic for this project or not. In this org we maintain a lot of packages we use in OpenWISP and we are generally overloaded with work to do and have very little time available to answer questions like this one.

I am closing this because it’s not a bug report nor an explicit feature request. If you find an answer to your question and you think this can become a feature request please reopen and add the necessary deatails and motivations.

I wish you good luck with your search!

Best regards Federico

Hi @henriod thanks for the detective work in DRF’s ImageField.

Unfortunately I’m a bit rookie to fully understand how to implement this within djang-rest-framework-gis. I’d have to do some research to see how this would be possible.
