RTK Survey

This reference explains RTK Survey for practical GIS, CAD and survey work while preserving the source data and project coordinate system.

Purpose and engineering use

Use this topic when planning a deliverable, checking field observations or exchanging data between design and mapping systems. Record the source CRS, units, datum realization, file format and expected tolerance before processing.

Recommended workflow

1. Inspect the source metadata and confirm the intended coordinate system.
2. Validate units, geometry, control points and attribute fields.
3. Process a small test sample and compare it with known coordinates.
4. Review residuals or visual overlays before exporting the final deliverable.

Accuracy and common mistakes

Accuracy depends on the datum, projection, survey control, transformation method and rounding applied during export. Common mistakes include mixing latitude/longitude order, using the wrong UTM zone, dropping elevation units, or treating a display conversion as a datum transformation.
