Implementation - Implémentation Maps

I wanted more information on the landcover data in the Maps App. When I clicked on the link I got a message that there is a new file available. Since this is updated yearly I was wondering if the updated file is also update in the Maps App?

Hi @Silvia888

Welcome back to the community, and thanks for posting in the Maps category! :tada:

Do you mean if the Google Earth engine that’s being used to integrate with DHIS2 Maps app has updated landcover data? Probably @Bjorn_Sandvik could answer this question :slight_smile:

Thanks!

Thanks for notifying us about the new version of the landcover dataset in Google Earth Engine. We will switch to this version for supported versions of DHIS2, 2.38 and above.

Hi team, just wanting to bring back the discussion around adding the new WorldPop population layers. WorldPop released high-resolution (100m–1km) gridded 2025 population data, including total counts, age/sex structures, and projected growth (2015–2030). These datasets are available via Google Earth Engine (WorldPop Global Project Population Data: Estimated Residential Population per 100x100m Grid Square  |  Earth Engine Data Catalog  |  Google for Developers). It would be great to update the 2020 data currently in the MapsApp. Thanks!

Hi Silvia! How are you?

Thanks for raising this.
We already have a draft PR: feat: new worldpop global2 layer sources [DHIS2-20774] by BRaimbault · Pull Request #3608 · dhis2/maps-app · GitHub

It needs a little bit of polish, but you can expect it to be ready in the next few weeks.
We also plan to update the import-export app.

Best regards,
Bruno

Yes! Well spotted!
It is also available in import-export-app and climate-tools.

We are planning a webinar early March to present the new dataset and how to use it in DHIS2, it should be announced soon.

That’s awesome thanks so much. Is there any chance you could add a higher resolution image backdrop layer as well. Right now the sentinel layers is quite blurry. We have seen that people who do not work with maps often benefit from seeing high resolution images as a backdrop. With the sentinel data roads (types), roof types, points of interest, etc. are not visible.

You can add “external map layers” via the Maintenance app to include other basemaps you have access to (via services like Google, MS Azure, ArcGIS, maptiler…).

Currently, I’m not aware of any open high-resolution imagery services with licenses that would let us provide this directly to users out of the box.

We can continue the discussion via email if you have recomendations here.
