# Integrating Orthomosaics

Spexi orthomosaics are high-resolution aerial maps that can be streamed directly into your GIS tools - no downloading required. Our tile services allow fast visualization and smooth navigation at any scale, whether you’re analyzing a single property or an entire city.

With Spexi integrations, you can:

* Add on-demand orthomosaic layers into your GIS workspace
* Control visibility, order, transparency, and other display settings like any raster map layer.
* Benefit from optimized performance through web-friendly tile delivery
* Use your existing GIS workflows for measurement and spatial analysis

### **Before You Start**

1. Log in to the [**Spexi World Viewer**](https://world.spexi.com)
2. Open the **Integrations** section
3. Copy either URL:
   * **WMTS URL**
   * **XYZ URL**

#### **Important -** [**Copy Your API Key**](/api-reference/authentication.md)

Your API key is displayed **once** when you create it and cannot be retrieved again.

Make sure you **copy and store it securely**.

### How to Integrate
