Field GIS
Field GIS connects what the map says with what people can see, measure, photograph and record on the whenua. A phone or tablet is enough for many jobs; the right tool depends on the work rather than the length of its feature list.
Start by audience and mahi
| If you are... | Common field work | Useful starting tool |
|---|---|---|
| marae team | assets, water tanks, generators, access, maintenance, emergency resources | KoboToolbox, Survey123 or Field Maps |
| taiao/kaitiaki team | awa observations, restoration, pests, weeds, repeat monitoring | QField, KoboToolbox, Field Maps or Survey123 |
| Māori land trust | whenua inspections, access, infrastructure, project visits | QField, KoboToolbox or Field Maps |
| cultural heritage/research team | site visits, photographs, current observations linked to historical evidence | QField or KoboToolbox |
| rangatahi project | GPS, photos, simple forms and learning the field-to-map loop | KoboToolbox or QField |
| existing ArcGIS organisation | map-based editing and structured forms | Field Maps and Survey123 |
| existing QGIS organisation | editing the same layers and styles used at the desk | QField |
Choose the collection pattern
Map first
Choose QField or ArcGIS Field Maps when collectors need to see existing features, navigate between them, edit geometry and work directly with map layers.
Form first
Choose Survey123 or KoboToolbox when the questions and validation are the centre of the workflow. The collector may only need one location plus a structured set of observations and photographs.
Mixed
Many mature workflows use both. A taiao project may maintain master site geometry in QGIS, collect repeat observations with Kobo forms, then join those records back to sites for analysis.
Tool guide
| Tool | Particularly useful when | Ecosystem |
|---|---|---|
| QField | the main GIS is QGIS and the field map needs the same layers/styles/forms | QGIS/open source |
| ArcGIS Field Maps | the organisation already uses ArcGIS Online/Enterprise | ArcGIS |
| Survey123 | structured forms are central and ArcGIS is already in use | ArcGIS |
| KoboToolbox | form-based collection needs to work across community/field contexts at low cost | open source/web + Android app |
For Kobo, use the detailed pathway: field work → form design → GPS/media → QGIS export.
Record only useful accuracy
A coordinate is a measurement. Phone GNSS can be useful for a culvert, planting site or field observation and completely unsuitable for defining a legal boundary. Record the device-reported accuracy where it matters and record whether geometry came from GNSS, imagery or another method.
Work offline deliberately
Before leaving coverage:
- open the project or form on the actual device
- confirm basemaps/forms are available offline
- collect several test records
- attach photographs
- close and reopen the app
- confirm unsynchronised records remain available
- return/synchronise and inspect the result in the desktop GIS
Field workflow examples
- Marae: collect asset condition and photographs, then combine the records with Marae GIS.
- Awa: collect repeat observations at stable site IDs, then add REC2/catchments and monitoring data.
- Restoration: record planting blocks and repeat survival observations, then compare against imagery.
- Historical research: record what is visible today while keeping the current field observation distinct from the historical source.
For a reusable field observation structure, create only the fields the project needs. A practical minimum is:
observation_id
observation_type
observed_date
status
notes
photo_reference
gps_accuracy
geometry_source
checked_by
See the Marae emergency map and Awa restoration worked examples for two different ways to apply this structure.
