DATAVIEW Interface
1. Visual Basic Script for ArcGIS
2. Uses ArcGIS GPS Extension
3. Uses NETCOMM serial driver
4. Script Modified from Initial Application by
Cawthron Institute.
5. Full Functionality of ArcGIS

Benefits of the Base DATAVIEW Interface
1. Follow previous or set cruise tracks
2. Navigate to existing GIS layers Bathymetry,
habitat, etc.
3. Groundtruthing
4. View map-based data in real-time.
5. Ease of operation within a regular monitoring
context.
6. Adaptive Sampling and Better Delineation of
Events
