- Abstract
- The "Hydrography" dataset is a polygon representation of New York City bodies of water. The data is comprised of polygon geometries with attribute information including water body name. Feature classifications include: 1. Lake/Reservior, 2. Pond, 3. River, 4. Stream wider than 8 feet, 5. Wetland, 6. Beach/Shoreline, 7. Bay/Ocean.
- Purpose
- Hydrography has been maintained and updated as a component of the New York City Basemap.

- Data Quality Information
- Horizontal Positional Accuracy Report
- All the NYCMap data was aerotriangulated and stereo-compiled to meet ASPRS Class 1 horizontal mapping standards and ASPRS vertical Class 2 accuracy specifications. The mapping standards deal with Root Mean Square (RMS) calculations that states if a random number of clearly identifiable surveyed ground control points throughout the project were compared to the mapped features, the RMS of the points would not exceed 2'. In layman's terms, 95% of the data is accurate to +/- 2'.
