Coordinates and heights are not changed without a confirmed method. A real zero remains zero; a missing value remains visible.

How Survey Control works, step by step.
Add the original survey file, confirm its technical context, review everything visibly and deliver one traceable project package.
From original survey to evidenced delivery.
What was measured in the field remains visible as the source. What is reviewed appears in the document. Only work assessed by a professional is released.

01 · SOURCE FILEThe source remains the source.
Start with the file exactly as supplied. Points, lines, layers and metadata are read locally without hiding the original survey behind a replacement version.
- TXT/CSV, DXF, GeoJSON, LandXML, GSI and GeoPackage
- File, hash and import warnings remain visible
- Missing values are never filled in silently

02 · MAP REVIEWContext first. Then review.
Country, CRS, axis order, units and height context are confirmed deliberately. The map then brings objects, layers and table values together in one visible review.
- Address search controls the camera, not the source CRS
- Map, table and selected objects remain connected
- Warnings remain visible until assessed

03 · DOCUMENTOne project state. One story.
The document preview uses the same source, map extent, metadata, notes and review status. Viewer and report therefore tell the same evidenced story.
- Cover, source reference and project details
- Map view, legend and visible review findings
- Preview first; final PDF only afterwards

04 · DELIVERYRelease only what can be evidenced.
After final review, the document and project data are assembled as one traceable package. The recipient sees the source, the checks performed and any deliberately retained issues.
- PDF report and project package share one release
- File list, status and warnings remain traceable
- The authorised user remains responsible for release

Automated checks help identify issues. The professional assesses context and decides what can be handed over.
Viewer, table, document preview, PDF and ZIP use the same source and review decisions.
