Import point data
Bring CSV, TXT, GeoJSON, KML, KMZ, GPX, or supported Shapefile data into the workspace.
Create Contours from Survey Points Online
Move survey points into contours and a related TIN surface without leaving a focused browser workflow.
When points need a clear next step
Raw point files can be difficult to review and communicate. TopoAssist helps turn imported data into contours and 2D or 3D views so teams can inspect the result before a handoff.
How TopoAssist helps
Generate and inspect
Generate contours and inspect the associated TIN surface in browser-based views.
Prepare supported outputs
Prepare supported CAD, GIS, LandXML, or PDF outputs when current access permits.
Who this workflow supports
Survey professionals and project teams who need an understandable path from point data to a reviewable surface result. Check source-data quality and coordinate-system information; professional verification remains important for engineering decisions.
