The TempAqua App for iOS is a mobile phone application that facilitates the mapping of intermittent streams. It is designed to make field work more efficient and less error-prone. A user collects the data in the field and then exports it directly to the database. The application helps him/her to navigate among mark-points, and record the stream-related data, including photos and videos. The application is configurable; A user can import mark points, stream network, and catchment shapes from geo-json files. The mapping mechanics is fairly simple. A user navigates to interested mark points based on his/her current location and imported catchment definition. He/she enters in the app the data collected in these locations, like current stream state, discharge, comment, photos, or even movies of the flowing stream. After all, he/she clicks a button to simply export the survey to the database.
