Keep geojson properties

[Dave-Evans]

I noticed this as well. For what it's worth, I was able to keep the properties when converting to Topology from a GeoDataFrame.

Hm, I think it should be copied over, can you please provide a small reproducible example including the data?

Hello, I'm having this issue as well. Note that when I copy and paste the code for input data of type "FeatureCollection or Features", the following is the JSON that is returned. Note that unlike the example response provided, this does not include the "properties": {"name": "abc"} attribute.
{
"type": "Topology",
"objects": {
"data": {
"geometries": [
{"type": "Polygon", "arcs": [[-2, 0]]},
{"type": "Polygon", "arcs": [[1, 2]]}
],
"type": "GeometryCollection"
}
},
"bbox": [0.0, 0.0, 2.0, 1.0],
"arcs": [
[[1.0, 0.0], [0.0, 0.0], [0.0, 1.0], [1.0, 1.0]], [[1.0, 0.0], [1.0, 1.0]],
[[1.0, 1.0], [2.0, 1.0], [2.0, 0.0], [1.0, 0.0]]
]
}

Thanks for re-raising the issue @sheep-queen! Including an example. I can reproduce it with both shapely 1.7.1 and 1.8. Not sure what is going on.

Thanks @Dave-Evans! That works for me too - convert my shapefile to GeoDataFrame then run topology and output as TopoJSON.
