A geospatial line feature representing the western portion of a 46kV electric supply cable from Hyannis, Cape Cod to Nantucket Harbor. The data was created by SCIOPS using geographic coordinates from a National Grid drawing dated February 2005, incorporating marine survey data from 1994.
Use Cases
- Analyze the cable's marine route coordinates for proximity to other seabed features.
- Model the cable's geographic path for integration with other coastal infrastructure datasets.
- Use the line feature for environmental impact assessments of seabed installations.
- Validate the cable's location against bathymetric or nautical chart data.
Strengths
- Line feature created from official utility company coordinates.
- Incorporates marine survey data from two periods in 1994.
Limitations
- Data represents a single cable line, not a network.
- Primary source drawing is from 2005, with survey data from 1994, indicating potential temporal staleness.
- No metadata on coordinate system, precision, or attribute columns.
