Example 3: Retrieving Gridded Elevation Data
We want to retrieve elevation data from a <Property Grid>
In the DRM, a <Property Grid> is a sub class of the abstract class <Data Table>.
To retrieve data from a <Data Table> we need to know:
- What is a <Data Table’s> Signature and Extents.
- What functions exist for retrieving data from a <Data Table>.
- What the format of retrieved data can be.
