## Sentinel-2 mosaics in OSM

* ESA program of earth observation satellites providing global color imagery, in 10 m resolution
* higher resolution than Landsat, but lower than commercial providers (Bing, ESRI, etc.)
* EC Copernicus License is OSM-compatible:
* See https://osm.org/wiki/Contributors#EU_Copernicus_.28GMES.29_data

## Sentinel-2 tiles in JOSM

* Sentinel-2 tile servers are available in JOSM (Preferences > Imagery), but not the most recent
* Now, let's fix that! :hammer_and_wrench:

---

* Sign-up for an account: browser.dataspace.copernicus.eu
* Sentinel Hub dashboard: shapps.dataspace.copernicus.eu/dashboard
* generate your **Instance ID** and determine your **Layer ID** to use in your configuration

---

In JOSM, go to Preferences > Imagery and add a new WMS entry

---


---

* GetCapabilities URL: `https://sh.dataspace.copernicus.eu/ogc/wms/YOUR_INSTANCE_ID?FORMAT=image/png&TRANSPARENT=TRUE&VERSION=1.3.0&SERVICE=WMS&REQUEST=GetMap&LAYERS=YOUR_LAYER_ID&STYLES=&CRS={proj}&WIDTH={width}&HEIGHT={height}&BBOX={bbox}`
* Name the layer

---

* Use `source=Sentinel-2` in your OSM changeset tag, if you used it for editing.
* Check your SH dashboard usage. There's a (low) monthly limit, so use it sparingly.
* Adjust the configuration for your needs:

----


---

### Wrap up

* When configured properly, you can just load the layer in your next editing session. No other configuration needed.
* Alternative sources:
* OpenAerialMap
* ESRI Wayback
* Public, high-resolution imagery are available from your government
* Any tips from participants?

### Thank you! 🍜
