Abstract
The "Open_space" dataset is a polygon representation of New York City parks and open space. The data is comprised of polygon geometries with attribute information. Feature classifications include: 1. Ball fields within park, 2. Cemetery Outline, 3. Hard surface courts within park, 4. Parking areas within park, 5. Playgrounds within park, 6. Pools within park, 7. Recreational area over 2 acres, 8. Skating rinks within park.
Purpose
"Open_space" has been maintained and updated as a component of the New York City basemap, known as NYCMap.

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'.
