This is a reef survey floor mat saved as a high resolution pdf file, to be printed on a large scale. The ATLAS project printed this on vinyl banner material 1.5m tall x 3m long. Printing companies can produce this for around €100. Alternatively, it can be printed on A3 paper for class/group activities.

There is also a Reef Survey pack in English, French, German and Spanish. This explains the activity and provides a kit list. There are corresponding keys for running the activity in English, FrenchGerman and Spanish. The answers can be found here.

You can find the high resolution file of the mat for download at the Zenodo repository here. Note it is the last of the files, appearing underneath the activity sheets and keys.
