Acquisition and Processing of a Detailed Aeromagnetic Survey Glass Buttes, Oregon

Using an ultra-light aircraft, a high-resolution aeromagnetic survey was carried out over Ormat Nevada's Glass Buttes project area in Oregon. Survey operations were completed on May 25, 2010. Average terrain clearance was 223 meters from the sensor. A total of 1,352 line-miles of aeromagnetic data were acquired. Processed survey data includes a total magnetic intensity map, reduced to pole (TMI) map, horizontal gradient (RTP) map, tilt derivative (RTP) map, and a horizontal gradient map of the tilt derivative grid.

本数据集采用超轻型飞机作为搭载平台，针对美国俄勒冈州奥马特内华达（Ormat Nevada）公司的格拉斯布茨（Glass Buttes）项目区开展了高分辨率航空磁测（high-resolution aeromagnetic survey）工作。本次航测作业已于2010年5月25日全部完成，传感器的平均离地高度为223米。本次航测共获取1352测线英里的航空磁测数据。经处理后的测量数据包含总磁场强度（total magnetic intensity）图、化极总磁强度（TMI）图、化极水平梯度（RTP）图、化极倾斜导数（RTP）图，以及倾斜导数网格的水平梯度图。
