# Class LatLonShape

java.lang.Object
org.apache.lucene.document.LatLonShape

public class LatLonShape extends Object
An geo shape utility class for indexing and searching gis geometries whose vertices are latitude, longitude values (in decimal degrees).

This class defines seven static factory methods for common indexing and search operations:

- `createIndexableFields(String, Polygon)` for indexing a geo polygon.
- `createDocValueField(String, Polygon)` for indexing a geo polygon doc value field.
- `createIndexableFields(String, Polygon, boolean)` for indexing a geo polygon with the possibility of checking for self-intersections.
- `createIndexableFields(String, Polygon, boolean)` for indexing a geo polygon doc value field with the possibility of checking for self-intersections.
- `createIndexableFields(String, Line)` for indexing a geo linestring.
- `createDocValueField(String, Line)` for indexing a geo linestring doc value.
- `createIndexableFields(String, double, double)` for indexing a lat, lon geo point.
- `createDocValueField(String, double, double)` for indexing a lat, lon geo point doc value.
- `createDocValueField(String, BytesRef)` for indexing a cartesian doc value from existing encoding.
- `newBoxQuery()` for matching geo shapes that have some `ShapeField.QueryRelation` with a bounding box.
- `newLineQuery()` for matching geo shapes that have some `ShapeField.QueryRelation` with a linestring.
- `newPolygonQuery()` for matching geo shapes that have some `ShapeField.QueryRelation` with a polygon.
- `newGeometryQuery()` for matching geo shapes that have some `ShapeField.QueryRelation` with one or more `LatLonGeometry`.
- `createLatLonShapeDocValues(BytesRef)` for creating the `LatLonShapeDocValues`

WARNING: Like `LatLonPoint`, vertex values are indexed with some loss of precision from the original `double` values (4.190951585769653E-8 for the latitude component and 8.381903171539307E-8 for longitude).
