DESCRIPTION:The Generic Mapping Tools (GMT\; www.generic-mapping-tools.org
 ) is a well-known set of software for the geosciences\, in particular in t
 he marine and solid earth disciplines. GMT is also a prerequisite for many
  other well-known software infrastructures\, including USGS’s ShakeMap f
 or near-real-time maps of ground motion and shaking intensity following si
 gnificant earthquakes\, MBARI/LDEO’s MB-System for multibeam processing 
 and mapping of the seafloor\, and Scripps Institution of Oceanography’s 
 GMTSAR for radar interferometric analysis and imaging of crustal deformati
 on. Today\, GMT has tens of thousands of users all over the world and rema
 ins essential for many terrestrial and planetary data processing and map-m
 aking workflows. GMT began its life over 30 years ago when I was a graduat
 e student\, and it has enjoyed continuous US National Science Foundation f
 unding since 1993. Leveraging this funding\, GMT has succeeded in establis
 hing itself as a collaborative Open Source community resource from the sta
 rt. Many scientists globally\, particularly European scientists\, have bee
 n instrumental in designing\, maintaining\, and improving GMT since the ea
 rly 2000s. As I and several of our core developers approach the end of our
  academic careers\, the GMT team has been pondering how to preserve these 
 collective investments and position GMT to remain an essential geoinformat
 ics infrastructure well into the future. In response\, we have made fundam
 ental changes to how GMT works\, enabling access to GMT modules from exter
 nal interfaces such as MATLAB/Octave\, Python\, and Julia\, simplifying us
 er access to large global datasets\, and extending our support for the Goo
 gle Earth platform. However\, the biggest impact delivered by the Fall 201
 9 release of GMT 6 is likely “modern mode”. Modern mode coexists with 
 classic mode (the only previous mode) so that thousands of GMT 4 and 5 scr
 ipts will still run as expected. Furthermore\, new users will start with m
 odern mode and experience a much-simplified GMT scripting syntax. A new as
 pect of GMT made possible by modern mode is a greatly simplified animation
  production. It is clear to all scientists that animations make it easier 
 to elucidate temporal or spatial changes\, yet very few scientists create 
 animations as they are traditionally the domain of experts. The GMT team a
 spires to make animations a task every scientist can do with ease. In this
  lecture\, I will discuss the latest news on GMT\, outline modern mode and
  the external environment access to our modules\, highlight a few GMT anim
 ations\, and present other aspects of our succession planning for strength
 ening the GMT community.
