#### Description

The Shuttle Radar Topography Mission (SRTM) digital
elevation dataset was originally produced to provide consistent,
high-quality elevation data at near global scope. This version
of the SRTM digital elevation data has been processed to fill data
voids, and to facilitate its ease of use.

### Code Editor (JavaScript)

```javascript
var dataset = ee.Image('CGIAR/SRTM90_V4');
var elevation = dataset.select('elevation');
var slope = ee.Terrain.slope(elevation);
Map.setCenter(-112.8598, 36.2841, 10);
Map.addLayer(slope, {min: 0, max: 60}, 'slope');
```
Python setup

See the [Python Environment](https://developers.google.com/earth-engine/guides/python_install) page for information on the Python API and using
`geemap` for interactive development.

```python
import ee
import geemap.core as geemap
```

```python
dataset = ee.Image('CGIAR/SRTM90_V4')
elevation = dataset.select('elevation')
slope = ee.Terrain.slope(elevation)

m = geemap.Map()
m.set_center(-112.8598, 36.2841, 10)
m.add_layer(slope, {'min': 0, 'max': 60}, 'slope')
