Managing surface models

The Compose Surface tool allows you to manage multiple surface models in the Compose Surface window. Your surface models can have several purposes. For example, you can extract depth values from the model and apply them to a navigational product like a paper chart or ENC or calculate slope across a surface to support pipeline planning. These products require that you are able to trace back to where the source data came from in cases of emergency. Therefore, a surface model is never permanently deleted from the BIS geodatabase in case it is required that a surface model be retrieved for official review.
