Emlid GPS receivers such as Reach RS2, RS2+, RS3, Reach RX, and Reach M series do not use traditional road navigation maps. Instead, map information is managed through Emlid Flow and Emlid Flow 360, where users can add satellite imagery, WMS layers, CAD drawings, GIS files, and survey data for field mapping.

This guide explains how to download and update Emlid map data for your surveying and GNSS projects.

Why Download Emlid Map Updates?

Updating map data helps improve:

• Satellite imagery visibility
• Survey project reference information
• GIS layer accuracy
• CAD drawing availability
• Field mapping workflow
• Project visualization

Emlid Flow supports map layers such as satellite imagery and WMS layers that can be added to survey projects.

3. Select your project.
4. Open Map Layers.
5. Choose Add Map Layer.
6. Select the required layer.
7. Save the project.

Emlid Flow 360 allows users to add WMS/WMTS layers such as topographic maps, orthomosaics, and satellite imagery.

Step 5: Add Custom Map Data

You can add project files such as:

• DXF drawings
• SHP files
• CSV data
• KML files
• WMS layers
• Surface models

Steps:

1. Open your project.
2. Select import options.
3. Upload your mapping file.
4. Adjust layer visibility.
5. Save changes.

Emlid Flow supports various surveying and GIS data formats for field workflows.

Step 6: Sync Maps With Emlid Flow App

After adding map updates:

1. Connect your phone/tablet to the internet.
2. Open Emlid Flow.
3. Sign in with the same Emlid account.
4. Open the updated project.
5. Wait for map layers to sync.

Projects with added layers from Emlid Flow 360 can be accessed in Emlid Flow using the same account.

Common Emlid Map Update Problems

• Use reliable internet when adding new layers.

Frequently Asked Questions

Does Emlid GPS have built-in navigation maps?

No. Emlid Reach receivers are GNSS positioning devices. Mapping information is handled through Emlid Flow, Emlid Flow 360, and connected GIS workflows.

How do I update satellite maps in Emlid Flow?

Open your project, select Map Layers, and enable the satellite map option.

Can I add custom maps to Emlid GPS?

Yes. You can add WMS layers, CAD drawings, GIS files, and other mapping data through Emlid Flow workflows.

Do map updates improve GPS accuracy?

Map updates improve visualization and project information. GNSS accuracy mainly depends on the receiver, antenna setup, satellite conditions, and correction services.

Conclusion

To download Emlid map updates, use Emlid Flow and Emlid Flow 360 to refresh satellite imagery, add WMS layers, and import GIS or CAD project data. Emlid receivers rely on connected mapping software rather than built-in navigation maps.

Keeping your map layers and projects updated helps ensure better field visualization and efficient GNSS surveying workflows.
