EpiCollect is a generic data collection tool that allows you to collect and submit geotagged data forms (along with photos) to a central project website (hosted using Googles AppEngine) from suitable mobile phones (Android or iPhone). For example, questionnaires, surveys etc. All data synchronised (ie a copy sent from the phone) from multiple phones can then be viewed / charted / filtered at the project website using Google Maps / Earth or downloaded.
Furthermore, data can be requested and viewed/filtered from the project website directly on your phone using Google Maps
