>The project was developed at the Escola Secundária Serafim Leite, in the aforementioned municipality of Aveiro, and was implemented by students Bruno Dylan, Diogo Resende, Jorge Correia and Nuno Castro, from the 12th year of the technical-professional Programming course.

The coordination of the work was the responsibility of Professor Fátima Pais, who explains that all stages of designing the application were verified remotely, since students maintain distance classes, and emphasizes that the project was completed "in record time", given "the enthusiasm of the kids and an incredible dedication, which reached 14 hours a day".

Already undergoing an evaluation process by the digital services distributor Google, which, in the current context of the covid-19 pandemic, requires software validation by national authorities to ensure that it does not violate individual rights, the 'app' will be free to use and it's called "SandSpace".

"At the base of everything is the work of research and georeferencing of all maritime and river beaches in the country, with name, location by county and district, indication of latitude and longitude, temperature and wind speed", reveals Fátima Pais to Lusa, mentioning that this map covers the entire continental coast and also that of the archipelagos of the Azores and Madeira.

From this base, the remaining functionalities depend on the contributions of those who are in the sands because it will be the users of each bathing space to provide the app with data on their human occupation, so that the software converts them into a graphic indicator in which the green means little density, yellow indicates an already considerable number of bathers, and red indicates a limited capacity.

This traffic light system will always reflect the average occupancy of the last 120 minutes and will also show the number of users who contributed to this same average. If the sign is yellow as a result of 50 contributions, for example, the app indicates when the green beach indications appeared and when the red stocking data appeared, so that it is clear how this bathing density has evolved in the last two hours.

The objective is for the application to "always present updated information" to users, whether they are already bathing or those who, at home or elsewhere, still want to assess the conditions of affluence to the nearest beaches to decide if it is worth the trip or if it is preferable to choose another destination or another date.

Already presented on the YouTube video platform with the speech by student Tomás Toscano and edited by his colleague Vasco Pinto, the application also lists the legal restrictions imposed by the SARS-CoV-2 virus pandemic at the present bathing season, so that users of the software can know the health restrictions in question and are made aware of compliance with the rules of distance and hygienic label.

"It is a project in the logic of 'crowd power' and, in addition to helping the population to avoid unnecessary trips to the beach, it also allows students involved in the project to further develop their technical skills and contribute to society with a really public utility ", concludes Fátima Pais.
