    • An imaging system includes a processor, a detection assembly configured to collect survey data characterizing a respective height and location of physical features of a geographic region, a receiver assembly configured to provide location data characterizing a geolocation of the geographic region, a tilt sensor configured to provide tilt data characterizing an inclination of the detection assembly with respect to gravity, and a magnetic-field sensor configured to provide field data characterizing a magnetic field associated with the geographic region. The processor is configured to perform processing of the survey data and tilt data to yield a first corrected data set, obtain magnetic-deviation data associated with the geographic region, determine an indication of true north, and process the first corrected data set and true-north indication to yield a second corrected data set comprising the first corrected data set oriented to true north.
    • 成像系统包括处理器,检测组件,被配置为收集表征地理区域的物理特征的相应高度和位置的测量数据;被配置为提供表征地理区域的地理位置的位置数据的接收器组件;配置为 提供表征检测组件相对于重力的倾斜的倾斜数据,以及被配置为提供表征与该地理区域相关联的磁场的场数据的磁场传感器。 所述处理器被配置为执行所述勘测数据和倾斜数据的处理以产生第一校正数据集,获得与所述地理区域相关联的磁偏差数据,确定真北的指示,并处理所述第一校正数据集和所述第一校正数据集, 北指示以产生包括朝向真北的第一校正数据集的第二校正数据集。
