You’ve probably used Google Maps to look for directions before, but did you know you can create your own custom map with it? The possibilities for customization are almost endless, and it’s a great way to easily organize and view your favorite locations on one map.

1. Open Google Maps and click the menu button in the top left corner.

2. Click Your Places > Maps > Create Map. 

3. Name your map and enter in a description.

4. Add markers for your desired locations. You can label these markers, add descriptions, change the color or shape, and add an image.

5. You can add walking, biking, or driving paths between two destinations.

6. You can also add additional layers by clicking on the Add Layer Button. This is useful if you’re creating a very dense map with lots of features and paths. ( You can choose differents colours).https://www.youtube.com/watch?v=hj9qnKz9NPc

IMPORTANT: Note that each school is going to use two different maps:

1 For measurements taken during daytime from 07 am to 19 h. We are going to divide the time every two hours. 07-09h, 09-11h, 11-13h...etc. Every two hours we will use a different layer. 

2 For measurements taken by the evening time 19-23h or night time 23-07h. Every two hours we will use a different layer. For the night time, what is supposed to have a few measurements, we will use just one layer. 

The most important maps is the first one whit measurements taken during daytime.
