# 如何建立地形貼圖
<a name="how-to-create-topographic-maps"></a>

Amazon Location Service 可讓您使用地形和輪廓密度功能建立地形貼圖，以視覺化方式呈現海拔變化和地理特性。

## 顯示希爾夏德
<a name="show-hillshade"></a>

地形功能可讓您視覺化 Hillshade、海拔變更和相關的地理功能。

### Hillshade 範例

## 使用等高線密度線顯示高度
<a name="show-contour-density"></a>

Amazon Location Service 可讓您將輪廓密度功能新增至地圖。這可提供地理陡峭度和高度變更的視覺化。

## 同時顯示希爾夏德線和輪廓密度線
<a name="show-hillshade-contour"></a>

使用 Amazon Location Service，您可以在地圖上結合希爾夏德和輪廓密度功能，以實現全面的地形視覺化。這可提供增強的深度感知，並完全了解地形變化和地形特性。
