【摘要】：在地質(zhì)工作中經(jīng)常遇到收集的圖件資料格式不一,如何轉(zhuǎn)換與共享一直是個難題,湖南省基礎(chǔ)地理信息1∶10000數(shù)字線劃圖入庫數(shù)據(jù)就是使用ESRI的E00通用交換格式,雖經(jīng)MapGis6.7文件轉(zhuǎn)換能自動轉(zhuǎn)換,但轉(zhuǎn)換后的點(diǎn)線面文件丟失圖形參數(shù),尤其注釋信息全無,無法還原,需手工逐步添加與修改,工作量大且易出錯,作者通過對MapGis6.7轉(zhuǎn)換后點(diǎn)、線、面文件進(jìn)行分析,并與E00格式文件進(jìn)行對比,找出對應(yīng)關(guān)系,提出注釋分字符中心點(diǎn)位算法,利用Visual Basic6.0編程,實(shí)現(xiàn)MapGis轉(zhuǎn)換后的點(diǎn)線面文件一次性自動轉(zhuǎn)換,完成地形圖E00格式到MapGis6.7格式的完全自動轉(zhuǎn)換與對接,簡化工作,提高效率,也為其它格式的入庫地形圖數(shù)據(jù)轉(zhuǎn)換提供參考與借鑒。
[Abstract]:In the geological work, the format of the collected map data is often different. How to convert and share the basic geographic information of Hunan Province is always a difficult problem. The basic geographic information of Hunan Province, 1: 10 000 digital line drawing data, is to use the E00 universal exchange format of ESRI. Although it can be automatically converted by MapGis6.7 file conversion, the transformed dot-line file has lost graphic parameters, especially the annotated information can not be restored, so it needs to be added and modified by hand step by step, and the workload is large and error-prone. The author makes use of the points and lines after MapGis6.7 conversion. The plane file is analyzed and compared with the E00 format file to find out the corresponding relation. The algorithm of the central point position of the annotated sub-character is put forward, and the point line plane file after MapGis conversion is realized by Visual Basic6.0 programming. Complete the automatic conversion and docking from E00 format to MapGis6.7 format of topographic map, simplify the work, improve the efficiency, and also provide reference and reference for the conversion of topographic map data in other formats.
