  • The web application ( is a realtime map of all recorded data. The users here can add new spots and records, or they can edit their previously recorded data. There are several other features of the web application, for more info, please see the web app tutorial file.


  • spots - locations on the map indicated by a marker

Adding new spot or record

Adding new spot or record

By clicking the Add new spot or record button on the Starting screen, you will be moved to the Map screen where you can either find your position by clicking the GPS icon or you can manually find the spot you wish to record by scrolling and zooming on the map. Your current location is always displayed by a black crosshair.

There are three ways of adding a new spot or record:

A) By GPS – Firstly, tap the GPS icon to find your current location. Then tap the Add new icon. By doing so, a new spot will be added to your current position.

B) By adding new spot elsewhere on the mapFind the desired location of the new spot on the map by scrolling and zooming. Tap on the map where you want to place a marker. A new marker will appear with blue outline. Then tap the Add new icon.

C) By adding a new record to an existing spotSelect an existing marker on the map by tapping it. The marker’s outline will turn to black. Then tap the Add new icon. You will now add a new record to the selected spot.

You can always cancel your selection by clicking the X icon.

Please note, that the recommended next step’s icon is always highlighted in blue.

Notes and warnings for adding new spots or records - GPS accuracy

Notes and warnings for adding new spots or records - GPS accuracy

GPS accuracy is shown at the bottom of the screen.

If the GPS accuracy is more than 100 m, the indicator will turn red.

If the accuracy is more than 200 m, a new spot cannot be added based on current position (A method) The GPS icon will turn red, and an error message will appear.

In case the GPS accuracy is too low, it is still possible to add a new spot by the adding new spot elsewhere on the map (B method) or by adding a new record to an existing spot (C method).

Notes and warnings for adding new spots or records - Close spots

Notes and warnings for adding new spots or records - Close spots

A warning message will pop up in case you try to add a new spot either by GPS (A method) or by adding new spot elsewhere on the map (B method) and there is an already existing closely located (<100 m) spot on the map.

There are three options to choose from.

  • You can continue with your selection (YES) if you are certain that you want to add a new spot (not recommended),
  • or you can cancel your progress (CANCEL) and go back to spot selection,
  • or you can activate the nearest existing spot on the map (ACTIVATE THE NEARBY SPOT).

Recording hydrological conditions

Recording hydrological conditions

After you pressed the Add new icon at the Map screen, you are moved to the Conditions screen. Firstly, you must select from the three condition options (Flow / Disconnected pools / Dry) the one which describes the site’s hydrological status the best.

In case you are adding a new spot, then you can enter its name. If you are adding a new record to an existing spot, then the name is already filled in.

After that, you can take a photo of the current conditions by clicking the Photo icon and pressing the Shutter button. You can take several photos for a spot/record.

Both entering the point's name and taking a photo are optional, however highly recommended steps. If you try to save a spot/record without a photo, a warning message will pop up to ask if you want to proceed with or without a photo.

Just as before, you can always cancel your progress by clicking the X icon.

Saving spot or record

Saving spot or record

If you are ready with all the processes, you can save your record by clicking the Save icon.

After that, you will be redirected to the Starting screen, where you can choose to add another spot or record or upload your saved items by clicking the Upload items button. It is possible to add more photos (shutter icon) to already saved items before uploading. You can also delete (trash bin icon) the saved items in case you do not want to upload them.
