针对GAMIT/GLOBK软件安装较为复杂、基线解算较为烦琐的问题,本文基于VMware Workstation 12.05虚拟机和Ubuntu 16.04操作系统,较为翔实地介绍了如何流程化快速安装GAMIT/GLOBK 10.7软件,并利用中国境内IGS站的观测数据进行了实例数据处理。本文在验证软件安装正确性的同时也为基线解算流程提供了思路。
随着倾斜摄影测量技术的快速发展,其凭借着低成本、高效率、低强度和高精度等一系列优点,广泛地应用在城乡空间数据建设的各个领域。在倾斜摄影完整生产流程的各项工艺中,空中三角测量作为内业处理的第一项工序,其结果将直接影响后续模型生产的效果和精度。本文以南方某城市约27 km2的倾斜摄影生产项目为例,使用Mirauge3D软件,通过不同参数的调整,探索其对空中三角测量结果的影响,以期为类似项目提供最佳技术
针对诸多GIS平台地图整饰功能存在自动化程度不高、整饰元素编辑不灵活、与地图数据分离等问题,依据规范标准对地图整饰元素进行分类,以面向对象的存储形式设计地图整饰数据模型,分析地图整饰自动化布局过程,基于制图表达机制和ArcGIS Object(简称"AO")二次开发实现地图整饰功能插件。该技术可在不同比例尺的地图制图项目中应用,大大提高了制图效率。
