# Elevation

The Bing Elevation service will enable you to query for elevation information for a set of points, polyline or a region on the Earth described by latitude and longitude pairs.

To use the Elevation API, it is necessary to create an **ElevationRequest**.

Property | Description |
---|---|

ElevationType |
Gets or sets the type of the elevation to be calculated. The available options for the : * List: Get elevations for latitude and longitude coordinates. Required parameters of the ElevationRequest.Points.* Bounds: Get elevations at equally-spaced locations within an area on the Earth defined as a bounding box. Required parameters of the ElevationRequest.Bounds, ElevationRequest.Rows, ElevationRequest.Columns.* Polyline: Get elevations at equally-spaced locations along a polyline path. Required parameters of the ElevationRequest.Points, ElevationRequest.Samples.* SeaLevel: Get the offset of the geoid sea level Earth model from the ellipsoid Earth model at a set of latitude and longitude coordinates. Required parameters of the ElevationRequest.Points. |

Points |
Gets or sets a set of coordinates on the Earth to use in elevation calculations. The exact use of these points depends on the type of elevation request. |

Bounds |
Gets or sets the rectangular area over which to provide elevation values. |

Rows |
Gets or sets the number of rows to use to divide the bounding box area into a grid. The rows that define the bounding box each count as two (2) of the rows. Elevation values are returned for all vertices of the grid. Integers with a value of two 2 or greater. The number of rows and columns can define a maximum of 1024 locations (rows * cols <= 1024). |

Columns |
Gets or sets the number of columns to use to divide the bounding box area into a grid. The columns that define the bounding box each count as two (2) of the columns. Elevation values are returned for all vertices of the grid. Integers with a value of two 2 or greater. The number of rows and columns can define a maximum of 1024 locations (rows * cols <= 1024). |

Samples |
Gets or sets the number of equally-spaced elevation values to provide along a polyline path. A positive integer. The maximum number of samples is 1024. |

Options |
Gets or sets the optional parameters for an elevation request. |
