How to eliminate double data entry in field surveys
Paper → spreadsheet → GIS → report. Four entry points, four chances for errors, and hours of unpaid admin every week. This guide explains why the pipeline exists and how to replace it with a single capture point in the field.
The four re-entry points
Most field survey workflows follow the same pattern, regardless of discipline. Data is recorded in the field, then manually transferred through a series of tools — each requiring someone to retype what was already written.
Paper form / notebook → Spreadsheet (Excel / Google Sheets)
Handwriting misread. Coordinates transposed. Species names misspelt.
Spreadsheet → GIS layer (QGIS / ArcGIS)
Coordinate columns swapped. Datum mismatch. Records silently dropped.
GIS / spreadsheet → Government portal CSV (AHIMS, BioNet)
Column headers don't match. Date format wrong. Missing mandatory fields.
All of the above → Report (Word / PDF)
Species count differs between spreadsheet and GIS. Map doesn't match tables.
The real cost
Let's do the maths for a typical ecology survey day.
| Metric | Value |
|---|---|
| Observations recorded per day | 40 |
| Time to re-enter each observation | 3 min |
| Daily re-entry time | 2 hours |
| Days in field per week | 3 |
| Weekly re-entry time | 6 hours |
| At $150/hr consultant rate | $900/week |
| Annual cost of re-entry (48 weeks) | $43,200 |
That's for one field worker. A 5-person team doing 3 field days a week is spending the equivalent of a full-time salary on retyping data that was already written down once.
Stop paying for re-entry
TerraSitu captures structured data, GPS coordinates, photos, and species records at the point of observation. Nothing gets retyped.
The solution: capture once at the point of observation
Offline-first mobile data collection eliminates the re-entry step entirely. Data is captured in structured digital forms — with GPS, photos, species taxonomy, and all required metadata — at the moment the observation is made. It syncs to the web portal automatically. From there, it flows directly into QA review, reports, and government exports without anyone touching a spreadsheet.
Before vs. after
Before
- ✗Paper forms in the field
- ✗Re-enter into spreadsheet
- ✗Copy coordinates to GIS
- ✗Format CSV for AHIMS/BioNet
- ✗Write report from scratch
- ✗Errors caught at report stage
After
- ✓Digital forms with GPS + photos
- ✓Data syncs automatically
- ✓GPS already embedded in records
- ✓One-click government exports
- ✓AI-drafted report sections
- ✓Errors caught in real time
How it works in TerraSitu
Set up survey with forms and GIS data
Create your project, import survey boundaries, choose form templates, and assign your team. Everything bundles into a single offline survey package.
Collect data offline on mobile
Your team downloads the package and works without a signal. Structured forms capture species, GPS, photos, and metadata at the point of observation. Species autocomplete works offline via cached ALA data.
Sync, review, and approve
When back in range, data syncs automatically. Review observations in the web portal — flag, approve, reject, or request re-survey. Coverage analysis highlights any missed areas.
Export and report
Export to BioNet, AHIMS, or any government portal in the format they expect. Generate report sections from your data — species registers, methodology, results. Deliver to your client.
Capture it once. Never retype it.
TerraSitu is pre-configured for Australian ecology and heritage legislation from day one. ALA species lookup, AHIMS and BioNet export templates, and 13+ field survey templates — all included.
