The Settings > Dataset page presents a list of datasets saved for the currently loaded configuration. (If a configuration is not loaded, go to Configuration.)
In most cases, the Dataset Type column will only show Network Full Data. If you are using data from Center Of Gravity, there is a column CoG Output.
In advanced use of Network Design, it is possible to create custom Dataset Types.
See Dataset Type.
To load a dataset:
Use the checkboxes to select a dataset (or datasets) and click Load Selected.
The line turns blue to indicate that the dataset is loaded.
After loading your dataset(s), a button Go to map appears. This takes you to the Home page where you can run the optimization model.
Or, if you want to check the data first, you can go to the Review section.
