基于三角形网格的气象场等值线自动分析

针对矩形网格法的不足，提出了用三角形网格法实现气象场等值线自动分析方法。通过对站点资料的边界插值、三角形剖分等处理后，再在剖分出来的三角形网格中按照一定方式连接等值线即可实现等值线的自动分析。给出了等值线自动生成算法，并将实例的分析结果同Grads绘制图进行对比分析。结果表明，该方法不仅有效可行，而且分析的结果更为精确合理。     

地质图切剖面中褶皱构造的计算机辅助编绘

计算机对褶皱的处理能力的强弱，是决定地质图切剖面计算机辅助编绘系统实用价值大小的一个重要指标。以兰姆赛分类方案为基础，通过褶皱形态的几何特征分析，提出一种针对简单背，向斜构造的计算机辅助设计算法，并编写出相应的褶皱剖面形态的模拟程序，利用各种不同形态的褶皱实例进行试验。证明该种算法正确可靠，将其嵌入作先前开发的地质图切剖面编绘程序中，可大大提高地质图切剖面编绘的自动化水平。

长距离非开挖穿越技术在岩石层、砂层的施工实践

立沙油品储运项目输油管道东江穿越工程,管道穿越水平距离为1085m。穿越地层主要为不同风化程度的花岗岩及砂层等复杂地层,其中穿越最硬岩石单轴饱和抗压强度达到36．7MPa,采用大型非开挖水平定向钻机进行施工。简述了施工测量及确定方位角、钻导向孔、扩孔及管道回拖等主要施工过程。通过采用加设直径300mm导向套管、布置人工磁场等施工措施,有效地保证了穿越轨迹与设计曲线重合;存泥浆中添加堵漏剂等外加剂,防止泥浆从岩石裂隙巾流失;在施工至砂层时增加泥浆粘度及添加润滑剂等措施防止塌孔．同时减小扩孔及回拖阻力：采用开挖发送沟并在沟内灌水,使管道存孔内保持悬浮状态等措施以减少管道的摩擦阻力,确保管道顺利回拖。     

面向直接入库的测量绘图系统的研制

针对现有地形图数据无损转换共享难、无法直接入库(Arc GIS)的问题,利用C#语言及VS2015开发环境,在AutoCAD2015平台下进行二次开发,设计出了一套面向直接入库的测量绘图系统。该系统采用ESRI公司的"CAD制图规范"中存放要素类的定义信息和要素的属性数据的组织规则,使得系统所绘图形不需要经过任何中间处理,就如同使用ArcGIS中的GeoDataBase地理数据库中的原生要素类和原生要素一样。测试结果表明,本系统较好地解决了上述问题,具有较高的应用价值。     

Force-directed layout of origin-destination flow maps

This paper introduces a force-directed layout method for creating origin-destination flow maps. Design principles derived from manual cartography and automated graph drawing to increase readability of flow maps and graph layouts are taken into account. The origin-destination flow maps produced with our algorithm show flows with quadratic Bézier curves that reduce flow-on-flow and flow-on-node overlaps, and avoid sharp or irregular bends in flow lines. A survey of expert cartographers found that flow maps created with our automated method are similar in quality to manually produced flow maps.
