Geometry types for use with ecto. Supported types include:

• GeoSQL.Geometry, a catch-all type
• GeoSQL.Geometry.Point
• GeoSQLGeometry.PointZ
• GeoSQLGeometry.PointM
• GeoSQLGeometry.PointZM
• GeoSQLGeometry.LineString
• GeoSQLGeometry.LineStringZ
• GeoSQLGeometry.LineStringZM
• GeoSQLGeometry.Polygon
• GeoSQLGeometry.PolygonZ
• GeoSQLGeometry.MultiPoint
• GeoSQLGeometry.MultiPointZ
• GeoSQLGeometry.MultiLineString
• GeoSQLGeometry.MultiLineStringZ
• GeoSQLGeometry.MultiLineStringZM
• GeoSQLGeometry.MultiPolygon
• GeoSQLGeometry.MultiPolygonZ
• GeoSQLGeometry.GeometryCollection

Example:

defmodule MyApp.GeoTable do
  use Ecto.Schema

  schema "specified_columns" do
    field(:name, :string)
    field(:geometry, GeoSQL.Geometry) # will match any Geo type
    field(:point, GeoSQL.Geometry.Point) # will reject any non-Point data
    field(:linestring, GeoSQL.Geometry.LineStringZ) # will reject any non-LineStringZ data
  end
end
