Create Geometry Objects? [QST] #91

Closed achapkowski closed 2 years ago

achapkowski commented 4 years ago

What is your question? I see you feed in numpy array, but since a shapely object or arcgis object is the most common geometry object, would it be better to feed in the object type into a column and convert it on the fly?

Thanks for the suggestion. We are developing a shapefile reader for polygons(which can also be applied to polylines) and the PR is under review. https://github.com/rapidsai/cuspatial/pull/86.

Andrew: do you think you can take the lead on this? We are under very strict resource constraints and community contributions are extremely welcomed. --Jianting

@thomcom @achapkowski I took at quick look at Fiona. I think the framework underneath can be used to convert cudf columns into python objects to get cuSpatial results back to third-party Python applications for additional processing. We need data flows both in and out of Python objects to interoperate with existing Python geospatial packages (at least for now).

Closing as this issue predates our shapefile support and GeoArrow support and other geometry I/O is covered by #165.
