Cadastre Querying

[codynhat]

How will the cadastre use and access parcel data? This will help determine if more indexes are needed (like using The Graph).

Some initial thoughts:

Mapbox GL JS

• Index parcels into GeoJSON?
  • Each parcel has it's own GeoJSON?
  • GraphQL response in GeoJSON?
  • How does The Graph store this data?
• Render with GeoJSON-VT?

Spun up a local Graph node. Should be able to listen to MintGeoWebParcel events, calculate a GeoJSON object for each newly minted parcel and add it to a subgraph.

Subgraph is deployed here.

It currently only returns a GeoJSON polygon for the base coordinate of a parcel.

• How do we represent an entire parcel? One single polygon? Or one polygon per coordinate?
• How can we follow a path in the subgraph mapping?
