Creation of public or private observations with possibility of adjustment for 24h in order to record the direction. Observations can be confirmed by anyone. Sharing private observations is reserved for a group or community for which they were made. SeeOnSea is worldwide usable, on all seas and oceans, and even on rivers and lakes. 5 types of observations are possible (that will be soon completed): - Fauna - Flora - Natural events - Human print (pollution, nets, containers, etc.) - Notable sites Our mini-wiki presents for each observation additional information with text and photos captured from Wikipedia or from one of our scientific partners. The search is intuitive with seasonality/dates and the possibility to select several types of observations. In addition to the basic functions, the concept includes: - An offline mode - A true multi language - An internal messaging - Multiple layers of presentation (relief, bathymetry, traffic, wrecks, protected areas, etc.) and many options to discover. A User Guide is directly accessible at the first login or in the menu. It is not mandatory to create an account to access the observation sharing map. Without account, access is done as "guest" ("Unknown" account) with some limited features but it is anyway possible to create and confirm observations. Many functions are being developed and will soon complete the current version. The goal is to show the wealth of our world by reaching out to as many people as possible to respect and protect it. Come and join us!
