Summary

This part of the USGS data release presents elevation data for the Little Holland Tract in the Sacramento-San Joaquin River Delta, California. During May and June of 2015, a team of scientists from the USGS Pacific Coastal and Marine Science Center (PCMSC) conducted multiple surveys (USGS Field Activity 2015-642-FA) to collect topographic and bathymetric data in Little Holland Tract, located in the Sacramento-San Joaquin River Delta between Liberty Island and the Sacramento Deep Water Ship Channel. Topographic mapping was conducted during low tide using a GPS backpack platform consisting of survey grade Trimble R10 and R7 global navigation satellite system (GNSS) recievers with Zephyr 2 antennas. Orthometric elevations relative to [...]
