Step 01Configure
Configure
and check
Create the survey project, configure the coordinate reference system and correction service, enter the pole height and verify a known control point.
Checks & results
- Quality checks
- Coordinate and height datum, correction source, pole height, quality status and a known point.
- Deliverable
- Project settings and the initial control check.
Why it mattersHelp prevent downstream coordinate mismatches.
Step 02Survey
Survey
site features
Measure the terrain and features with consistent codes. Record the receiver/app version and any interruptions or poor conditions.
Checks & results
- Quality checks
- Codes, coverage, quality status, model/app version and interruptions.
- Deliverable
- Raw coded observations with field notes.
Why it mattersCarry the site context into the office with the data.
Step 03Complete
Complete
quality checks
Check coverage, perform an independent closing check and resolve outliers. A fixed RTK solution alone does not establish survey accuracy.
Checks & results
- Quality checks
- Independent closing check, missing features and anomalous observations.
- Deliverable
- Closing-check results and resolved exceptions.
Why it mattersReduce avoidable return visits for missing observations.
Step 04Export
Export
and validate
Export in the agreed CAD/GIS format. Open the file, retain original data, and document processing time or manual edits.
Checks & results
- Quality checks
- Open the final file; record units, format, processing time and manual edits.
- Deliverable
- Original data, the validated export and supporting notes.
Why it mattersReduce file preparation and clarification at handover.

Is this the right workflow for a terrain survey?
Choose this workflow when the job calls for measured control, terrain points and site features. For continuous 3D surfaces or complex geometry, also consider georeferenced LiDAR.
Which files can the office receive?
Trion Survey lists formats including DXF, SHP, CSV-compatible ASCII and other survey formats. Confirm the exact export and coordinate system for your CAD or GIS package.
