# NIDLTDOAMeasurement.FloorElevation

An object that describes how high off the ground DL-TDOA anchors reside in the environment.

## Declaration

```swift
class FloorElevation
```

## Overview

Overview Floor elevation specifies the vertical position of DL-TDOA anchors. In multi-story deployments, floorNumber specifies the floor that the anchor resides on. The  height property describes the anchor’s elevation off of the floor, in meters. Negative floorNumber values indicate areas below ground level, for example, a basement or parking level.
