Import some geo data

curl -X POST -H "Content-Type: application/json" -d '
{
  "geometry": {
    "type": "Point",
    "coordinates": [59.37131802330678, 18.16711393757631]
  },
  "properties": {
    "name": "Secret room",

  }
}
' localhost:5984/shelters

Create a spatial index

curl -X POST -H "Content-Type: application/json" -d '
{
  "_id": "_design/SpatialView",
  "st_indexes" : {
    "shelter_positions": {
      "index" : "function(doc) { if (doc.geometry) { st_index(doc.geometry); } }"
    }
  }
}' localhost:5984/shelters
