# The Google Earth Engine App used by Collect Earth to display NDVI and Landsat/Sentinel imagery is not working or very slow

Asked by collector on 2026-05-08

The Google Earth Engine App used by Collect Earth to display NDVI and Landsat/Sentinel imagery is not working or it is really slow loading the graphs.

This started happening last week around the time that Google Earth Engine updated their license to Tiers.

## Question

The Google Earth Engine App used by Collect Earth to display NDVI and Landsat/Sentinel imagery is not working. How can I update the URL used by Collect Earth?

## Answer

Due to recent changes in Google Earth Engine, the URL previously used by Collect Earth to connect to the Google Earth Engine App for NDVI data and Landsat/Sentinel imagery had to be changed.

Until this is included in a future Collect Earth update, you can manually configure the new URL in Collect Earth.

## Steps to update the URL

1. Open **Collect Earth**.

2. Go to:

   **Properties -> External Services**

3. Disable the option:

   **Google Earth Engine App without login**

4. In the last field, where you can configure the URL for the **Extra Map**, enter the following URL:

   ```
   https://fao-earth-map.projects.earthengine.app/view/collect-earth-plot#geoJson=GEOJSON;plotId=PLOT_ID;
   ```

5. Click:

   **Save and Apply Changes**

6. Try opening the plots again and check whether the NDVI and Landsat/Sentinel imagery are now displayed correctly.

## Important requirement

You need to have the **latest version of Collect Earth** installed for this configuration to work.

## Additional note

This change is related to the Google Earth Engine App URL. If the problem continues after updating the URL, the issue may be unrelated to the URL change and could be linked to another configuration or licensing issue.
