About

Features

Use FieldForm to conduct location-bound measurements in the field, store the values on your phone, and share the measurements with other people. To use FieldForm for a set of locations with multiple people simultaneously, the use of an FTP-server is recommended. FieldForm is the successor to FieldLogger. It is build platform-independent in Flutter. The new structure makes it easier to add functionality or fix bugs. FieldForm is now completely open source. For more information, see the Github-page. For FieldLogger-users: there are some important changes between the files used or generated by FieldLogger and FieldForm. The file with location-data is a json file (instead of a csv in FieldLogger), to better incorporate the nested structure of the location-data. The measurement-data still consists of csv-files. The date-format however is changed to yyyy-mm-dd (instead of dd-mm-yyyy in FieldLogger), to minimise potential errors.
