## Look up elevation at one or more points

`client.Elevation.LookupPost(ctx, body) (*ElevationLookupResult, error)`

**post** `/api/v1/elevation`

Look up elevation at one or more points

### Parameters

- `body ElevationLookupPostParams`

  - `Format param.Field[string]`

    Response format: json (default), geojson, csv, ndjson

  - `Lat param.Field[float64]`

    Latitude (single point)

  - `Lng param.Field[float64]`

    Longitude (single point)

  - `Locations param.Field[string]`

    Pipe-separated lng,lat pairs (batch)

  - `OutputFields param.Field[string]`

    Comma-separated property fields to include

  - `OutputInclude param.Field[string]`

    Extra computed fields: bbox, center

  - `OutputPrecision param.Field[int64]`

    Coordinate decimal precision (1-15, default 7)

### Returns

- `type ElevationLookupResult struct{…}`

  GeoJSON Point Feature with a 3D coordinate [lng, lat, elevation] per RFC 7946 §3.1.1. The elevation is also available in `properties.elevation_m` for convenience.

  - `Geometry GeoJsonGeometry`

    GeoJSON Geometry object per RFC 7946. Coordinates use [longitude, latitude] order. 3D coordinates [lng, lat, elevation] are used for elevation endpoints.

    - `Coordinates GeoJsonGeometryCoordinatesUnion`

      Coordinates array. Nesting depth varies by geometry type: Point = [lng, lat], LineString = [[lng, lat], ...], Polygon = [[[lng, lat], ...], ...], etc.

      - `type GeoJsonGeometryCoordinatesPoint []float64`

        [longitude, latitude] or [longitude, latitude, elevation]

      - `type GeoJsonGeometryCoordinatesLineStringOrMultiPoint [][]float64`

        Array of [lng, lat] positions

      - `type GeoJsonGeometryCoordinatesPolygonOrMultiLineString [][][]float64`

        Array of linear rings / line strings

      - `type GeoJsonGeometryCoordinatesMultiPolygon [][][][]float64`

        Array of polygons

    - `Type GeoJsonGeometryType`

      Geometry type

      - `const GeoJsonGeometryTypePoint GeoJsonGeometryType = "Point"`

      - `const GeoJsonGeometryTypeLineString GeoJsonGeometryType = "LineString"`

      - `const GeoJsonGeometryTypePolygon GeoJsonGeometryType = "Polygon"`

      - `const GeoJsonGeometryTypeMultiPoint GeoJsonGeometryType = "MultiPoint"`

      - `const GeoJsonGeometryTypeMultiLineString GeoJsonGeometryType = "MultiLineString"`

      - `const GeoJsonGeometryTypeMultiPolygon GeoJsonGeometryType = "MultiPolygon"`

  - `Properties ElevationLookupResultProperties`

    - `ElevationM float64`

      Elevation in meters above mean sea level (WGS84 EGM96 geoid)

  - `Type ElevationLookupResultType`

    - `const ElevationLookupResultTypeFeature ElevationLookupResultType = "Feature"`

### Example

```go
package main

import (
  "context"
  "fmt"

  "github.com/plazafyi/plaza-go"
  "github.com/plazafyi/plaza-go/option"
)

func main() {
  client := githubcomplazafyiplazago.NewClient(
    option.WithAPIKey("My API Key"),
  )
  elevationLookupResult, err := client.Elevation.LookupPost(context.TODO(), githubcomplazafyiplazago.ElevationLookupPostParams{

  })
  if err != nil {
    panic(err.Error())
  }
  fmt.Printf("%+v\n", elevationLookupResult.Geometry)
}
```
