Basic Usage

Here are a few workflows which should help you to get started with this web application. If you are missing a description here, please send a an email. Thank you.

Uploading new data

  1. Visit the Select tab.
  2. If you want to add a topography to an existing surface, press its "Properties" button. Otherwise press the "Create surface" button and fill out the form, press "Save".
  3. The detail page for the surface opens. Press "Add topography" and follow the dialogue.

Analyzing surfaces and topographies

Comparing analysis results from multiple surfaces/topographies

  1. First visit the Select tab, and use the checkboxes to select one or more surface and/or topographies. You can see the topographies by clicking on the small triangle on the left-hand side of a surface's name. The selected items appear in the bar underneath the top navigation bar, which always shows the current selection.
  2. Switch to the Analyze tab.
  3. Select one or more Analysis function by clicking on their checkboxes, e.g. choose Height Distribution and Power Spectrum.
  4. Press the button "Update results".
  5. For each analysis function a card is shown. You can use the toolbar at the plot to zoom/pan etc. or download the plot. Some analysis plots may provide additional feature's. They are accessible by pressing the "Open" button. Then a new tab opens showing only results for the related analysis function.

Showing analysis results for a single surface or topography

If you want to analyze a single surface or topography, there are also alternative ways:
  1. First visit the Select tab, and find the topography you are interested in. Press the "Analyze" button. Then automatically, this surface is selected with all of its topographies and the "Analyze" tab is loaded.
  2. If you want to analyze a single topography, you can also enter the surface by pressing "Properties", then in the bandwidth plot, press the bar with the corresponding topography, and when the detail page for the topography opens, press "Analyze this topography". The old selection is then replaced by this topography, and the Analyze tab opens.

Supported File Formats

Extending the supported file formats is a continuous work in progress. If

  • you have a question or problem regarding the upload of topography data, or
  • your file is not supported, or
  • you need more information on this page here,
please send us an email or open an issue on GitHub. Thank you for your help.

The following file formats are supported. Please click on a file format name in order to expand the description for that format:
