Observo is an App allowing you to create observations and events (like natural phenomenon, damage assessment, surveillance, inventory, etc.). Your observations can be made freely or can be based on existing objects. All records are localized on a map. In addition to generic observations (photos, voice record, text) multiple and customizable forms can be defined according to your daily tasks. A simple tap on a button will allow you to send your data per email to a configured location for a further processing. Your data will be formatted and displayed within a resulting report (incl. photo and map extract). Available features: - Mandants - Integration of WFS and WMS for additional map materials - Import from configurable objects - Free and based-on object observations - Integration of multiple forms and lists of choices - Customizable reports as output (pdf, word, excel) Observo accelerates and coordinates processes which are requiring data collection on site. Observo is easy to integrate with existing applications and workflows.
