I found out that sanity supports Geopoint type, but I could not find any information if it's possible to do any filter operation on this type. Are geospatial queries possible?
Simpler syntax for geospatial queries is on the roadmap.
If you for instance want to make a Lat/Lng bounded query, you can do that the following way, given the schema:
export default {
name: 'aDocumentType',
type: 'document',
fields: [
{
name: 'position',
type: 'geopoint'
}
]
}
Let's say we have used Mapbox, and have a LngLatBounds object. Now we can make a query, using the params that maps to this object:
*[
_type == "aDocumentType &&
position.lng < $bounds._ne.lng &&
position.lat < $bounds._ne.lat &&
position.lng > $bounds._sw.lng &&
position.lat > $bounds._sw.lat &&
]
