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
Multiple Viewing Options 1. Map 2. Text 3. Chart
