If your sensors are located incorrectly on the map on the GROW website, it’s possible to enter the GPS coordinates for the correct locations.
Before doing that, you will need to find these coordinates. If you need help with how to do that, please use the information below.
Using a smartphone
1. Install the Google Maps app on your phone and open it.
2. If you are standing next to the sensor, click on the compass in the bottom right corner and continue with step 5.
3. If you are not at the sensor location, move the map to the sensor location and zoom in to the highest zoom level. You can change to a different map layer (e.g. Satellite) by clicking the button in the top right corner if this allows for more accurate positioning of the sensor.
4. Touch the screen for several seconds at the location of the sensor. A red pin appears.
5. Depending on your phone type, the coordinates are shown in the search box at the top or you need to touch the pin to reveal the coordinates.
6. Copy or write down these coordinates.
Using a computer
1. Go to http://maps.google.com
2. Navigate on the map to the sensor location and zoom in to the highest zoom level. You can change to a different map layer (e.g. Satellite) by clicking the button in the lower left corner if this allows for more accurate positioning of the sensor.
3. Click on the map where the sensor is located. A box appears in the bottom with the address and coordinates.
4. Click on the coordinates in the box. The coordinates appear in the left side panel.
5. Copy the coordinates from the left side panel (the small numbers with a decimal point and no symbols).
How to enter correct coordinates
Once you have the coordinates, you can enter them on the GROW website.
Go to the ‘My Data’ page – https://hub.growobservatory.org/my-data/sensors
Click the sensor you wish to reposition. You can click the name on the left hand column or the marker on the map.
Click the green ‘Edit’ button.
You will see boxes where you can enter the latitude and longitude values. Like in the image below.
Enter the numbers and click ‘Update’.
Repositioning using the map pins
If you wish to move the sensor just a very small distance, you can also drag and drop the pin on the map. However, this method is not recommended for changing a location by more than a few metres.
