Design a Kobo form for GIS

A useful field form is a data model with a phone interface. Start with the records you need back in QGIS, not with every Kobo question type.

Start with one record

For an awa observation, a compact structure could be:

FieldPurpose
observation_iddurable key such as AWA-2026-0042
site_idlinks repeated visits to the same site
observed_atdate/time
teamteam or collector code where useful
observation_typecontrolled list
conditioncontrolled list or score
notesshort text
locationGPS point
photoone or more images where useful

The same pattern works for a marae asset inspection or restoration visit by changing the subject fields.

Use choices where consistency matters

Dropdown/select questions are useful for status, condition, species groups, work type and other categories that will later be symbolised or filtered. Free text is better for observations that genuinely cannot be predicted in advance.

Do not make every field compulsory. A required question should be required because the downstream GIS or project needs it, not because the software has a toggle.

Use stable identifiers

People's names, descriptions and labels can change. A stable site_id, asset_id or observation_id makes repeated monitoring, joins and updates much easier.

If the project already has IDs in QGIS, reuse them rather than inventing a second identifier system in Kobo.

Repeat visits

For long-term taiao monitoring, distinguish the site from the visit. One site can have many observations over time. That structure supports trend analysis and avoids creating a new unrelated point every time somebody returns.

Form languages

Kobo supports multilingual forms. Use te reo Māori where it is the language that makes sense for the people collecting the data. Keep field names used by the database short and stable while labels shown to people can be more natural.

Test the awkward cases

Before rollout, test:

  • blank optional values
  • very long notes
  • more than one photograph
  • no mobile coverage
  • poor GPS accuracy
  • a repeated visit to an existing site
  • a collector who chooses the wrong category and needs to correct it

Then inspect the export in QGIS before collecting hundreds of records.

Next: GPS and media and KoboToolbox to QGIS.
