- Method Detail
  - getMinimumValue
```
Double getMinimumValue()
```
    Returns the lowest vertical extent contained in the dataset.
    
    Returns:
    
    Double mandatory for valid content, may be null for an invalid document.

```
Double getMaximumValue()
```
    Returns the highest vertical extent contained in the dataset.
    
    Returns:
    
    Double mandatory for valid content, may be null for an invalid document.
  - getVerticalCRS
```
VerticalCRS getVerticalCRS()
```
    Provides information about the vertical coordinate reference system to which the maximum and minimum elevation values are measured. The CRS identification includes unit of measure.
    
    Returns:
