After you have successfully exporting the txt file, you will be able to use it generate the topological graph.
Currently, we do not have a customized software for you to use. But there are a lot of different software doing such operation. For example, QGIS, ArcGIS, etc. Some of the software are not free to use.
We are working on either create a simple software for visualize the mapping results or find a software company that we can cooperate with. So please feel free to contact us if you know such company that are interested!
We are also interested to see the results of your mapping graph! Feel free to contact us if you would like to share!
