Kongsberg Simrad公司生产的EM系列多波束测深仪将所采集的原始数据以ALL格式的二进制方式存储,这种存储方式虽然较为节省空间,却不方便数据处理和参数分析。有时在处理过程中发现问题,也无法通过读取和修改源数据进行修正。为便于数据处理及误差分析,以VB6.0作为开发平台,编写ALL格式分析系统,通过读取ALL文件中的数据,直观显示水深结果,并且提取需要的参数进行数据的分析和校正。
The EM series multi-beam depth sounder manufactured by Kongsberg Simrad stores the raw data collected in binary format in ALL format. Although this storage method is more space-saving, it is not convenient for data processing and parameter analysis. Sometimes problems are detected during processing, nor can they be corrected by reading and modifying the source data. In order to facilitate the data processing and error analysis, VB6.0 as a development platform, the preparation of ALL format analysis system, by reading the ALL file data, visual display depth results, and extract the required parameters for data analysis and correction.
