Global Mapper Adds Improved 3D Viewing and Visualisation Tools

Blue Marble Geographics has announced the immediate availability of Global Mapper version 18.1. This upgrade to the version 18 release includes numerous functional enhancements throughout many areas of the software and it introduces an array of new tools, upgrades to existing components, performance improvements to increase efficiency and productivity, and support for several new formats and online data sources.

去年9月的全球映射版本版本的版本引入了一个完全重新设计的接口，具有显着改善的层和工作流管理以及大幅增强的3D显示。在这个基础上建立，版本18.1.进一步改善了具有新选项的3D体验，以在相邻的2D视图中工作的同时冻结3D视图，渲染栅格或3D模型格式时的速度改进，以及改进用于创建3D飞行的功能的功能。对于LIDAR模块用户，现在可以使用新的数据QC工具来调整点云高度以匹配调查的地面控制点。

3D数据的重要性

The release of version 18.1 offers numerous enhancements that are a testament to the ever-increasing importance of 3D data. Global Mapper's 3D view, which introduced the ability to display an "infinite view" of all loaded 3D data in version 18, now offers the option to pause the 3D rendering when interacting with the 2D map. This streamlines workflow and significantly improves memory usage by eliminating the need to continually refresh the display. The rendering speed for 3D raster layers as well as 3D models has also been drastically improved. When creating a 3D fly-through visualisation or recording, the flight parameters now include bank angle, to more realistically simulate a pilot's eye view, and variable velocity, allowing the flight speed to be adjusted between segments.

版本18.1中的其他增强功能包括一个新选项，可以计算定义区域内光栅层中的颜色统计信息的摘要;更快地装载和显示大矢量文件，如shapefiles;支持许多新格式，包括导出LandXML和导入RMAPS / MBTILES和BPF LIDAR文件;并扩展在线数据选项，包括海洋（Gebco）的一般浴室图表。

Points

Users of the optional Global Mapper Lidar Module, which provides advanced point cloud processing tools, can now perform precise quality control of their data against established ground control points. This allows the elevation values associated with each point to be adjusted to conform to the surveyed elevations at these locations.

随着越来越多的数据有一个高度或elevation component, the importance of Global Mapper's 3D viewing capability is underlined, stated Blue Marble's president, Patrick Cunningham. For several years, the development priority has been to optimise the user experience when interacting with Lidar, DEMs or other 3D layers and with the release of version 18.1 we are seeing some of the results of that effort with more display control, improved 3D interaction, and stunning 3D visualisation, he added.
