Title
Edison 2 Foot Contours [New Jersey]
Description
This dataset represents 2 foot contour lines in Edison, Middlesex County, NJ. This data was provided in a deliverable with several other elevation projects in 2017 by EagleView. See below for more information: EagleView acquired highly accurate Light Detection and Ranging (LiDAR) elevation data for Middlesex County, NJ in April 2017 and May 2017. This dataset represents Middlesex County, NJ. The area of interest is comprised of approximately 343 square miles. Data is in NAD_1983_2011_StatePlane_New_Jersey_FIPS_2900_Ft_US, NAVD88 Geoid12B, US survey Feet. LiDAR for this dataset was classified and quality controlled by EagleView. Digital Elevation Models, Contours, and Hydrographic breaklines were generated by Ground Point and subsequently quality controlled by EagleView. LiDAR nominal point spacing was 0.387 meters and point density was 6.674 points per square meter. The RMSEz was computed to be 0.09 meters. AccuracyZ has been tested to meet 18.2 cm Fundamental Vertical Accuracy at 95 percent confidence level using (RMSEz * 1.9600) as defined by the National Standards for Spatial Data Accuracy (NSSDA); assessed and reported using National Digital Elevation Program (3DEP)/ASPRS Guidelines. LiDAR data meets USGS Quality Level 2 (QL2) standards. Contours were derived from LiDAR.
