Class `GeoPoint` represents a point on the earth's surface represented by latitude and longitude coordinates.

`GeoPoint` is defined in the module `google.appengine.api.search`.

## 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:

```python
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)
         ]
```

For more information about performing location-based searches, please see `https://docs.cloud.google.com/appengine/docs/standard/services/search/query-strings#queries_on_geopoint_fields`.

## Constructor

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.

    Exceptions

    TypeError

    :   Any of the parameters has an invalid type, or an unknown attribute was passed.

    ValueError

    :   An invalid value was passed for one of the parameters.

## 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.
