View of GeoJSONDataSource (e.g. CDSview but for Geodata)

Hi,

Apologies for the lack of code but I’m more in a planning stage and I’m definitely entry level. I’ve built a gmap of polygons and points (seperate geojsondatasources).

A great feature of Bokeh is being able to filter or “view” part of a columndatasource (https://docs.bokeh.org/en/latest/docs/reference/models/sources.html#bokeh.models.sources.CDSView).

Q1) I was wondering if this view concept is possible for GeoJSONDataSource (polygons) as it would make it easier for building an app and passing around a single source for callbacks on the Bokeh server but being able to plot multiple layers.

Q2) Alternatively, is it possible to plot polygons patches from a column datasource onto gmap or a tileprovider, this way I could access the cdsview

Regards,
Sarah
