In April 2017, the Monroe County Department of Environmental Services-Geographic Information System (GIS) Services Division contracted XEOS Imaging to acquire LiDAR data over the entire county. A total of 9 missions were flown with a Cessna 206 Turbo aircraft (C-GPXA) equipped with a LiteMapper 6800 system including a Riegl LMS-Q680i 400 KHz laser scanner. The final absolute accuracy of LiDAR points is estimated to be 11.7 centimeters with a 95% confidence level. Each point was post-processed in NAD83 (2011) State Plane New York West Zone, US Survey Feet. The vertical datum is NAVD88.

Flight Configuration Data:

Pulse density per flight line (pls/m2): 5.4

Nominal laser pulse rate (kHz): 300

Effective laser pulse rate (kHz): 200

Scanning angle (deg): 60

Flying speed (knots): 100

Flying height above the ground level, AGL (m): 625

Swath overlap: 30%

Scan frequency (lignes/second): 120

Vert/Horiz Accuracy: 11.7 cm with 95% confidence

Point spacing: 0.43 meters

Total area captured: 705.48 square miles

The GIS Division offers LiDAR data consisting of contour lines and digital elevation model rasters in ESRI Geodatabase format. This data format can be extracted into shapefiles or GeoTiffs and should be usable in most GIS and CAD programs. A sample for Cobbs Hill Park can be downloaded here.
