Tie Every Survey
To Ground Truth

Solve the grid-to-ground coordinate transform with a least-squares Helmert fit, then see your control, points, and CAD in a live 3D scene.

Features

From control points to a 3D site,
in one tool.

Everything a surveyor needs to tie an architect's grid to the real world and see it in space.

Coordinate-tie

Solve the grid-to-ground tie with a 4-parameter Helmert least-squares fit, with per-point residuals and an RMS you can trust.

Conversion & inspector

Convert any point across building grid, projected northing/easting, and lat-long — EPSG-selectable, grid vs ground, in feet or meters.

Point import

Bring survey-machine exports straight in via CSV or LandXML, organized into categories and groups.

3D visualization

See control, grid, and points in a live 3D scene over real terrain — imported elevations stay the source of truth.

DXF overlay

Drop the architect drawing into the scene, georeferenced — full DXF vector overlay aligned to your transform.

Export

Export converted coordinates and full project data back out as CSV or LandXML when the job is done.

Pricing
