This layer contains the locations of all buoys in Lake Tahoe. This data was collected using GPS devices during the Summer of 2016. CA Method: Data represents GPS/GNSS location data and associated attributes for mooring floats (buoys) on the California side of Lake Tahoe\u2019s shorezone (El Dorado County and Placer County). Field data were collected in July and August of 2016 using a blue-tooth enabled Bad Elf Surveyor GPS/GNSS unit with attributes logged into a custom Fulcrum application (fulcrumapp.com). The software applications for the GPS/GNSS unit (Bad Elf) and Fulcrum app were supported/maintained using an Apple iPad mini tablet (iOS 9.3.5). The Bad Elf Surveyor GPS/GNSS unit used was equipped with a real-time differential correction (56 channel receiver that supports GPS (US) and QZSS (Japan) constellations with SBAS (WAAS/EGNOS/MSAS). Overall horizontal accuracy (HDOP) was assessed from .gpx data records representing stationary positions to be 0.927m (SDev=0.247m, n=140143, max=10m, min=0.6m).
