[Spec] Spatial Data Types

Spatial Data Types

Introduction

We should have a basic set of spatial data types built in. They can then be extended by other developers to add something like "asGeoJson" for example.

Proposal

All proposed types are open for discussion.

input CoordinateInput {
    x: Int!
    y: Int!
}

type Coordinate {
    x: Int!
    y: Int!
}
"----------------------------------------------------------------"
input PointInput {
  srid: Int
  coordinate: CoordinateInput!
}

type Point {
  srid: Int!
  coordinate: Coordinate!
}
"----------------------------------------------------------------"
input LineStringInput {
  srid: Int
  coordinates: [CoordinateInput!]!
}

type LineString {
  srid: Int!
  coordinates: [Coordinate!]!
}
"----------------------------------------------------------------"
input PolygonInput {
  srid: Int
  coordinates: [[CoordinateInput!]]!
}

type Polygon {
  srid: Int!
  coordinates: [[Coordinate!]]!
}
"----------------------------------------------------------------"
input MultiPointInput {
  srid: Int
  coordinates: [CoordinateInput!]!
}

type MultiPoint {
  srid: Int!
  coordinates: [Coordinate!]!
}
"----------------------------------------------------------------"
input MultiLineStringInput {
  srid: Int
  coordinates: [[CoordinateInput!]]!
}

type MultiLineString {
  srid: Int!
  coordinates: [[Coordinate!]]!
}
"----------------------------------------------------------------"
input MultiPolygonInput {
  srid: Int
  coordinates: [[[CoordinateInput!]]]!
}

type MultiPolygon {
  srid: Int!
  coordinates: [[[Coordinate!]]]!
}

This would almost be like GeoJson:
