Exercise
As an exercise at this staage of the course, consider the advantages and disadvantages of the use of each of these different types of 3D models and also try to give examples of one or two applications these type of models could be used for.
Use the table below as a guide.
| Advantages | Disadvantage | Application | |
|---|---|---|---|
| DTM | Simple ground model. Ideal for basic ground modelling. |
Only contain the ground height and does not hold any information on the height of features on the ground. | Flood modelling Highway engineering General terrain visualisation |
| DSM | |||
| Contour | |||
| 3D Block | |||
| 3D Visualisation |
We have completed on part of the table to help you start. Try to fill in the rest individually or in groups.
