Collaborative Research: Improving the Generic Mapping Tools for Seismology, Geodesy, Geodynamics and Geology

1347184 wesselear地理信息学计划（NSF 11-581）资助了一项为期三年的项目，该项目旨在开发用于分析和显示地球科学数据的通用测绘工具（GMT）软件包的增强功能。GMT现在包括80多个模块，这些模块共享一组通用的命令选项、文件结构和文档。它被广泛用于制作出版质量的图形演示文稿。GMT现在有超过25000个个人注册用户。该合同将支持对GMT能力的扩展，包括：1)用于绘图的代码，来自GPS测量的速度矢量及其不确定性作为带置信度椭圆的箭头，地震震源机制作为地图上正确地图的半球投影，三元图和地质符号；2) GMT和Python之间的应用程序编程接口（API），以支持计算工作流脚本；3)干涉合成孔径雷达（InSAR）处理和分析工具，用于与地震断层、活火山、冰川移动和不稳定滑坡相关的地表变形的空间分辨成像，以及石油、天然气、地热流体和二氧化碳的工程提取和/或注入。开发的GMT源代码将在GNU宽松通用公共许可证下免费发布。＊＊＊

1347184WesselThis EAR Geoinformatics Program (NSF 11-581) grant supports a three year project to develop enhancements to the Generic Mapping Tools (GMT) software package for analyzing and displaying geoscience data. GMT now includes more than 80 modules that share a common set of command options, file structures, and documentation. It is used widely to produce publication-quality graphic presentations. GMT now has more than 25,000 individual registered users. This award will support expansion on GMT capabilities to include: 1) code for plotting, velocity vectors from GPS measurements and their uncertainties as arrows with confidence ellipses, earthquake focal mechanisms as hemispherical projections on cartographically correct maps, ternary diagrams and geologic symbols; 2) an Application Programming Interface (API) between GMT and Python to support computational workflow scripting; and 3) tools for Interferometric Synthetic Aperture Radar (InSAR) processing and analysis for spatially resolved imaging of Earth surface deformation associated with earthquake-generating faults, active volcanoes, moving glaciers, and unstable landslides, as well as the engineered withdrawal and/or injection of petroleum, natural gas, geothermal fluids, and carbon dioxide. The developed GMT source code will be distributed, free of charge, under the GNU Lesser General Public License. ***
