The EarthScope/GMT Analysis and Visualization Toolbox

EarthScope保护伞下的研究既涉及数据处理，也涉及结果显示。通用绘图工具(GMT)是一套在地球科学中广泛使用的科学分析和绘图模块，特别是因为它们允许适合地球科学的专门处理和成像。GMT是一个寿命长(约30年)、由NSF资助的强大软件工具包，它起源于海洋科学，但已传播到地球科学的方方面面，甚至更远。该项目将为GMT添加许多增强功能，包括一种非常简化的用法语法，称为现代模式。此外，在该项目期间，将建立新的模块，用于简化动画的创建、网格的3D叠加和内插、图像转换以放置在Google Earth中，以及大大改进的交互文档。通用地图工具(GMT)脚本在其存在的30年中保持着惊人的相似之处。由于已经编写了数以千计的GMT经典脚本，做出重大更改一直是有问题的，即使这样的更改可以简化其使用。提议的现代模式将解决这一难题，因为它引入了开始和结束现代模式会话的两个新命令(Begin和End)。因此，不使用这些命令就不可能意外地进入现代模式，从而允许所有现有的GMT脚本原封不动地运行。一旦进入现代模式，所需的语法将被简化，以避免重复的选项，用户将不再负责汇编合成的PostScript文件。默认输出格式为PDF，但可以选择多种格式，包括标准的栅格图像格式。将添加改进的交互文档以展示现代模式(同时保留经典模式的文档)。为了加强EarthScope的科学，将有新的模块用于3D网格堆叠和内插，为Google Earth构建KML图像四叉树，以及一个新的动画模块，它极大地简化了构建科学动画的任务。预计UNAVCO将协助针对在壳牌、MatLab或Python环境中使用GMT的EarthScope科学家举办的年度研讨会。这一奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

Research under the EarthScope umbrella involves both data processing and display of results. The Generic Mapping Tools (GMT) is a set of scientific analysis and plotting modules that are widely used in the Earth Sciences, particularly because they allow for specialized processing and imaging suitable for the geosciences. GMT is a long-lived (~30 years) and robust NSF-funded software toolset that originated in the ocean sciences but has spread to all aspects of the geosciences and beyond. This project will add numerous enhancements to GMT, including a much simplified usage syntax called modern mode. In addition, new modules for simplifying the creation of animations, 3-D stacking and interpolation of grids, conversion of imagery for placement in Google Earth, and greatly improved interactive documentation will be built during the project.The Generic Mapping Tools (GMT) scripting has remained remarkably similar over its 30 years of existence. Because thousands of GMT classic scripts have been written, making major changes has been problematic, even if such changes would simplify its usage. The proposed modern mode will solve this dilemma as it introduces two new commands (begin and end) that starts and end a modern mode session. Hence it is not possible to accidentally enter modern mode without the use of those commands, thus allowing all existing GMT scripts to run unchanged. Once in modern mode, the required syntax will be simplified to avoid repetitive options and the user will no longer be responsible for assembling a composite PostScript file. The default output format will be PDF but more than one format may be selected, including standard raster image formats. Improved interactive documentation will be added to showcase modern mode (while maintaining the documentation for classic mode). To strengthen EarthScope science there will be new modules for 3-D grid stacking and interpolation, KML image quadtree building for Google Earth, and a new animation module that vastly simplifies the task of building scientific animations. It is anticipated that UNAVCO will assist with annual workshops aimed at EarthScope scientists using GMT in shell, MATLAB, or Python environments.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
