Produced from 27 color infrared photos taken December 17, 2002. Orthorectification accomplished with Imagine software. The overall positional accuracy for the photomosaic is 3.25 meters RMSE. The dataset was developed for use by the Staten Island Unit of Gateway National Recreation Area as a GIS component and for digital monoplotting and mapping. 20021217 ground condition Complete Unknown Staten Island Unit of Gateway National Recreation Area -74.145808 -74.047642 40.616108 40.526645 none Orthorectification Color Infrared mosaic aerial photo CIR imagine leaf-off none New York Gateway National Recreation Area National Park Gateway Staten Island none December 2002 none none Sara Stevens Data Manager, Northeast Coastal and Barrier Network mailing and physical address

PDF Bill Frament ERDAS Imagine IMG File and Mr. SID Compressed File none Staten Island Unit of Gateway National Recreation Area Overall positional accuracy of 3.25 meters RMSE. Horizontal accuracy was assessed on the basis of 21 field survey points distributed throughout the image and collected by Kathy Mellander. The actual field coordinates for these points were recorded with a Trimble ProXRS GPS unit with real-time differential correction with a minimum of 120 (180 unless field conditions were poor) fixes per point. The field coordinates were then compared to the image mosaic coordinates for these points, determined in ESRI ArcMap.

The photos were scanned at 600 dpi and imported into Imagine. The individual DOQQs were mosaiced to create a single file for use as ground control. The images were orthorectified in ERDAS Imagine software using the DOQQs and the DEM as ground control. The orthorectified images were then sent to North Carolina State University to be mosaicked into a single seamless basemap using ER Mapper. The final seamless mosaic was compressed using Mr. SID software at a 1:20 target compression ratio. 200306 Northeastern Research Station mailing address
