基于MapGis平台可视化筛选无人值守航空物探数据

Visual screening the unattended data of airborne geophysical survey based on the MapGis platform

近年来,随着无人值守航空物探测量工作方式的逐步推广,数据处理流程发生相应的变化。基于航测数据质量要求,利用MapGis二次开发功能,将实测数据绘制成具有属性结构的航迹图,通过对航迹线的编辑,筛选出满足质量要求的测量数据。此方法对于数据筛选具有速度快、针对性强的特点,同时可以更好了解数据质量和工作进度,具有较好的实用效果。

Recent years,as the model of unattended airborne geophysical survey has gradual popularized and applicated,the flow of data processing has corresponding changes,too.Based on the quality requirements of airborne geophysical survey data,the program of edit data was complied using function of secondary development of MapGis.First,the measured data are draw into map of flight track with attributes;then flight tracks are edited;finally the data that meet quality requirements are obtained.The practices show this method has better effects.This is not only rapid and targeted at data screening,but also can understand data quality and working progress.
