- 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'. Estimated accuracy: 95% of the data is accurate to +/- 2 feet How this value was determined: 95% of the data is accurate to +/- 2 feet
