Disclaimer: This data has not been updated since 2016
This layer contains the locations of all buoys in Lake Tahoe. This data was collected using GPS devices during the Summer of 2016. The purpose of this project was to record location coordinates and provide a baseline accounting of mooring floats/buoys in support of a Lake Tahoe shoreline planning project. TRPA collected the GPS data on the NV portion of Lake Tahoe (mostly in July 2016) and the Spatial Informatics Group, under contract with TRPA and CA State Lands, collected data on the CA portion of Lake Tahoe (July 2016 until September 2016). |

This data was collected using GPS devices during the Summer of 2016. </SPAN></P><P><SPAN>CA Method: Data represents GPS/GNSS location data and associated attributes for mooring floats (buoys) on the California side of Lake Tahoe’s 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). Field data were collected and processed by Spatial Informatics Group, LLC as a contract deliverable for the Tahoe Regional Planning Agency and the California State Lands Commission.</SPAN></P></DIV></DIV></DIV> |

While Spatial Informatics Group, LLC, TRPA and California State Lands Commission endeavors to deliver accurate data, this data should not be used for site-specific evaluation, surveying, or engineering purposes - field validation of mooring locations is highly recommended for this purpose because mooring float positions frequently change in response to wind and wave direction, and are often moved or removed over time in response to lake levels and/or other seasonal conditions. Data should also not be used beyond the limits of the source scale. Comments on this data are invited and TRPA’s GIS Department would appreciate receiving information about inaccuracies found herein (contact gis@trpa.org). Use of this data is considered acceptance of the limitations of this data and that the user has read and understood this metadata prior to its use in any form.
