Abstract
This talk will give a comprehensive overview of the latest developments and progress of the GRASS GIS project for users and developers.
The talk will cover topics relevant for integrating GRASS GIS engine into existing workflows. We will dispel some common misconceptions
about the project, such as "it's just a command line", "it's just a desktop GIS", “it's a QGIS plugin” and "it's been around for a
long time, so it must be well funded".
Many potential users perceive GRASS GIS as difficult to use. During the talk, we'll cover different improvements to the graphical
interface that are aimed at addressing this problem. The switch to a mature single-window layout, an easier startup, streamlined
data management and the upcoming command history pane are all improvements attempting to increase user-friendliness and make it
easier for newcomers to adopt GRASS GIS.
The talk will also go through a series of improvements relevant for industry and academic users to facilitate the integration
of GRASS data processing and analytic tools in their workflows using Python or R, either on the command line or in the cloud.
Examples of these improvements are the parallelisation of many modules with OpenMP enabling accelerated processing of large
data sets and the stricter compiler configurations ensuring code quality in C, C++ and Python.
Finally, the latest community activities and funding opportunities will be presented.
