UC Merced Vernal Pools and Grassland Reserve GPS and Elevation Survey Points 2015

A topographic survey was conducted using a Trimble R8 Global Navigation Satellite System (GNSS) receiver (Trimble, Sunnyvale, California, USA) applying the real–time kinematic (RTK) technique to gather surface topographic and GPS data with an elevation accuracy of +/– 2 cm and spatial resolution accuracy of +/– 1 cm. 4,254 survey points were collected during the summer of 2015.

本数据集采用天宝R8型全球导航卫星系统（GNSS）接收机（美国加利福尼亚州森尼韦尔市天宝公司生产），通过实时动态差分（RTK）技术采集地表地形与GPS数据，其高程精度为±2厘米，空间分辨率精度为±1厘米。2015年夏季共采集4254个测量点。
