This talk gives an overview of the current state of the GRASS GIS project for both users and developers. It will cover topics relevant for integrating GRASS GIS into existing workflows and projects and for contributing to this community-driven open-source project. Reflecting on the 40th birthday, the talk will try to address some common misconceptions about the project such as “it is command-line only”, “it is only a desktop GIS,” and “it’s been around for long, so it must be well-funded.”
First, the talk will cover improvements to the graphical user interface (GUI). Warranted or not, many potential users perceive GRASS GIS as difficult to use; the new versions (8.0, 8.2, 8.3) are changing many parts of the GUI to address this problem and make it easier for first-time users to adopt GRASS GIS. The GUI is now switching to a single-window layout as this new layout matured and became the number one choice of even advanced users. This adds to an already established easier startup without a need for a welcome screen and streamlined data management in the GUI.
The talk will also cover a series of improvements called for by industry and academic users including simplified session management and streamlined command line interface. This will transition into the various ways of how GRASS GIS can be used for geospatial data processing in Python, R, QGIS, command line, and in the cloud.
Relevant to quality assurance, the code quality of C and C++ code improved significantly in the last year. The code compiles with more strict compiler settings than ever with the Clang compiler and we are heading towards pedantic compliance with the GCC compiler. Similarly, Python code improved significantly in the past few years and more improvements are underway and will be covered in the talk.
New funding options - now available through OpenCollective - will be presented in the talk in the hope of sparking a discussion during the conference about meeting our funding goals.
This talk will also report on GRASS GIS Community Meeting 2023 in Prague where the participants celebrated the 40th birthday of GRASS GIS by contributing more code.
While this talk is presented by a single speaker, the project is a combined work by many organizations and individuals. GRASS GIS is an OSGeo Project, currently developed on GitHub with oversight from the Project Steering Committee elected by the project contributor community at large.
