#### Description

The Actueel Hoogtebestand Nederland (AHN) is a dataset with detailed and
precise elevation data for the whole of the Netherlands. Elevation
information was collected from helicopters and aircraft using laser
technology with vertical accuracy of 5 cm.

AHN3 Dataset contains the Netherlands AHN 0.5m DSM and DTM variables.
The data cover the period between 2014 and 2019.

The Digital Terrain Model (DTM) product represents the elevation of the
ground, while the Digital Surface Model (DSM) product represents the
elevation of the tallest surfaces at that point.

### Bands

**Bands**

Pixel size: 0.5 meters (all bands)

| Name | Units | Pixel Size | Description |
|---|---|---|---|
| `dtm` | m | 0.5 meters | Elevation of the ground |
| `dsm` | m | 0.5 meters | Elevation of the tallest surfaces at that point |
