摘要
在地质工作中经常遇到收集的图件资料格式不一,如何转换与共享一直是个难题,湖南省基础地理信息1∶10000数字线划图入库数据就是使用ESRI的E00通用交换格式,虽经MapGis6.7文件转换能自动转换,但转换后的点线面文件丢失图形参数,尤其注释信息全无,无法还原,需手工逐步添加与修改,工作量大且易出错,作者通过对MapGis6.7转换后点、线、面文件进行分析,并与E00格式文件进行对比,找出对应关系,提出注释分字符中心点位算法,利用Visual Basic6.0编程,实现MapGis转换后的点线面文件一次性自动转换,完成地形图E00格式到MapGis6.7格式的完全自动转换与对接,简化工作,提高效率,也为其它格式的入库地形图数据转换提供参考与借鉴。
In geological work often encountered collected maps of varying data formats, how to convert and sharing has been a problem, Hunan, geomatics 1: 10000 DLG data warehousing is the use of ESRI's E00 common interchange format, despite M apG is6.7 file conversion can be automatically converted, but the converted file is missing the point, line and plane graphics parameters, in particular, no annotations, you can not restore, you need to manually add and modify gradually, heavy workload and error-prone, the author of MapGis6.7 after the conversion point, line, surface files are analyzed and compared with the E00 format file, find the corresponding relationship between the proposed sub-character comment center bit algorithm, using Visual Basic6.0 programming, MapGis converted file once-point line of automatic conversion, complete topographic map of E00 format to M apG is6.7 fully automated docking with the format conversion, simplifying the work to improve efficiency, but also provide reference and experience for the storage of topographic map data conversion to other formats.
