Export SQL CREATE TABLE from Collect - species list missing
Dear friends, I sometimes use the SQL export to get a build statement for the database structure resulting from the survey definition (for example to create a database or to visualize it). In this export, however, the species list is missing. E.g. if you use DBschema (as free software to visualize i...
Check record completeness in collect and collectmobile
Hello, How can I rapidly check the completeness of a record, i.e. the proportion of the planned sampling points for which data has been collected? It would be nice to add a field in OF Collect (and CollectMobile) indicating that data was collected for x% of the sampling point. Is it possible? Thank ...

Dynamic response to posteriori changes

Hi all, I am not sure if this has been answered somewhere already, but I have a complex hierarchical code list. Some level1 categories DO NOT have any additional categories on level2 (or level3).
