## Instance Methods

Close httplib2 connections.

Locates the building whose centroid is closest to a query point. Returns an error with code `NOT_FOUND` if there are no buildings within approximately 50m of the query point.

### Method Details

`close()`

    Close httplib2 connections.

`findClosest(experiments=None, location_latitude=None, location_longitude=None, requiredQuality=None, x__xgafv=None)`

    Locates the building whose centroid is closest to a query point. Returns an error with code `NOT_FOUND` if there are no buildings within approximately 50m of the query point.

    Args:
      experiments: string, Optional. Specifies the pre-GA features to enable. (repeated)
        Allowed values
          EXPERIMENT_UNSPECIFIED - No experiments are specified.
          EXPANDED_COVERAGE - Expands the geographic region available for querying solar data.
      location_latitude: number, The latitude in degrees. It must be in the range [-90.0, +90.0].
      location_longitude: number, The longitude in degrees. It must be in the range [-180.0, +180.0].
      requiredQuality: string, Optional. The minimum quality level allowed in the results. No result with lower quality than this will be returned. Not specifying this is equivalent to restricting to HIGH quality only.
        Allowed values
          IMAGERY_QUALITY_UNSPECIFIED - No quality is known.
