Capabilities

Move survey points into a focused surface workflow.

TopoAssist helps you import survey point data, generate contours and TIN surfaces, inspect results in 2D and 3D, and prepare supported CAD, GIS, LandXML, and PDF outputs when current access permits.

Built around practical survey tasks

Import survey points

Bring CSV, TXT, GeoJSON, KML, KMZ, GPX, and supported Shapefile data into the workspace.

Generate and inspect

Generate contours and inspect the associated TIN surface in browser-based 2D and 3D views.

Prepare supported outputs

Prepare DXF, GeoJSON, KML, KMZ, GPX, CSV, Shapefile ZIP, LandXML, and PDF outputs as supported by your current access.

Review source-data quality and coordinate-system settings before relying on an exported result. Professional verification remains important for engineering decisions.
