# Updating the Satmap

It’s hard to accurately assess the results of these modifications without generating a new satmap. Since we’re working with large areas, a high-altitude camera view is often required, where only the satmap textures are visible. Therefore, updating the satmap is frequently necessary to see the final quality of your work.

<p class="callout warning">****Warning****: Updating the satmap, followed by refreshing all terrain textures, can be very time-consuming. In our 256 km² project, on a modest setup (like an Nvidia 1060 GPU), these steps take a minimum of 45 minutes</p>

#### Steps to Update the Satmap

1. ****Export All Surface Textures****: Export the updated surface textures.

2. ****Generate a New Satmap****:  
    <span style="white-space: pre-wrap;">Our team uses the </span>[<span style="white-space: pre-wrap;">ReforgerSatGenerator </span>](https://github.com/granQ/ReforgerSatGenerator)Python script by Daniel Granquist, which has saved us substantial time (a big thanks to him!).
3. ****Import the New Satmap****: Import the newly generated satmap into Enfusion.
4. ****Save and Wait for Tile Updates****: Save your project and wait for all tiles to update, which can take 20–30 minutes on similar configurations.

This update is essential for evaluating how your modifications look across large areas of terrain.
