DtCoverage (NetCDF-Java All API v5.5.3)

java.lang.Object
- ucar.nc2.ft2.coverage.adapter.DtCoverage

All Implemented Interfaces:

IsMissingEvaluator
```
public class DtCoverage
extends java.lang.Object
implements IsMissingEvaluator
```
fork ucar.nc2.dt.grid.GeoGrid for adaption of GridCoverage. Minimalist, does not do make a "logical GeoGrid subset" LOOK maybe can only be used for GRID ?
