I'm trying to develop gis based web application. I'm using leaflet for frontend and django for backend. My requirement is to plot raster data in leaflet. I'm using rasterio for reading raster file. And here is my View to read raster file upload by the user
class UploadRasterView(View): def post(self, request): context = dict() raster = RasterFileUploadForm(request.POST, request.FILES) folder_name = 'raster_data' if raster.is_valid: file_name = '' for _file in self.request.FILES.getlist('file'): handle_uploaded_file(_file, folder_name) if _file.name.split('.')[-1] == 'tif': file_name = _file.name file_location = settings.MEDIA_ROOT + '/' + folder_name + '/' + file_name data = rasterio.open(file_location) print(type(data)) return JsonResponse(context)
Up to here everythings is working fine but i didn't know to serialize this data, os data i can plot raster data in leaflet.
