3D topography explorer
Work with a height grid, not scalar roughness parameters. Inspect the surface, extract profiles and export reproducible descriptive calculations.
This tool does not replace an ISO 25178 evaluation. Results describe the input grid without filtering, form removal or evaluated uncertainty.
Input data
Local processing. Nothing is sent to a server. The uploaded file is not retained when this page closes.
Enter 3–60 rows with 3–60 numeric values in each. Use decimal points and semicolons, tabs or spaces to separate columns. All rows must have the same length. Specify XY pixel spacing and the height unit.
