Step 1: Plotting Data on a Shared Online Map

You will be sharing the data recorded by your water probe on UMap, which allows users to create their own maps embedding the data of their choice.

First, head to https://umap.openstreetmap.fr/fr/

You ll need to create an account to be able to edit your own maps.

Once you ve successfully logged in, hit the “Create a map” button.

You can now draw markers and enter the description you wish to publish.

For example, let’s enter the value recorded by our water probe at Lake Harriet, in Minneapolis.
We’ve recorded 100 microsiemens, which by the way means that it is safe to bathe in Lake Harriet!

To share this map with anyone, you just need to provide them with the appropriate link.

Go to Update permissions and editors.

You can choose who can view and who can edit this map.
To enable editors to edit the map, copy the link of your map (the web address of your map) and share it with whoever you want.
