Introduction
The GeoPoint class allows you to make map locations searchable. You start by instantiating the GeoPoint class and then pass that object to a specific document field:
from google.appengine.api import search ... # Construct the GeoPoint class geopoint = search.GeoPoint(latitude, longitude) fields = [search.TextField(name='name', value=store_name), search.TextField(name='address', value=store_address), # Construct a GeoField passing geopoint as the value of that field search.GeoField(name='store_location', value=geopoint) ]

The constructor for class
GeoPoint
is defined as follows:
-
GeoPoint ( latitude , longitude )
-
A point on the earth's surface represented by latitude and longitude coordinates.
-
Arguments
- latitude
-
The angle between the equatorial plan and a line that passes through the GeoPoint, between -90 and 90 degrees.
- longitude
-
The angle east or west from a reference meridian to another meridian that passes through the GeoPoint, between -180 and 180 degrees.

Properties
An instance of class
GeoPoint
has the following properties:
- latitude
-
An angular distance, in degrees, from the equator. Points located to the south of the equator have negative values, while points located to the north of it have positive values.
- longitude
-
An angular distance, in degrees, from the prime meridian. Points located to the west of the prime meridian have positive values, while points located to the east of it have negative values.
