Affiliation: (Department, University, Country) School of Climate, Environment and Society, Clark University, Massachusetts, USA;Dr. Robert Gilmore Pontius Jr, Gil for short, has been a Geography Professor since 1998 at Clark University in the USA. He creates quantitative methods that contribute to Geographic Information Science, Land Change Science, Remote Sensing, and Statistics. His work has generated more than 21 thousand citations. He is guest co-editor of a special issue in the journal Land concerning applications of Trajectory Analysis, which is a method to describe changes in a time series of maps using free software in R and Python.

Affiliation: (Department, University, Country) Department of Earth and Environmental Sciences, Lund University, Lund, Sweden;Lars Harrie is professor in Geographic Information Science (GIS) at Lund University, Sweden. He is involved in research and teaching of technical and theoretical aspects of GIS. His main interests are algorithms for processing, analyzing and visualizing geographic data in both 2D and 3D as well as methods to improve the national spatial data infrastructure. He is also interested in applications of GIS and have performed spatial analysis research in e.g. urban planning, historical demography, epidemiology and hydrology. During recent years his research focus has mainly been 3D city models.

Department of Computer Science, University of Calgary, Calgary, Canada;Faramarz F. Samavati is a Professor in the Department of Computer Science at the University of Calgary. His research spans computer graphics, geoinformatics, and visualization, with a focus on Discrete Global Grid Systems (DGGS) and Digital Earth. He co-authored the Open Geospatial Consortium's DGGS Abstract Specification and has led pioneering research on grid-based Digital Earth frameworks for geospatial data management and analysis. His recent honours include two Canadian national awards: the 2026 Canadian Human-Computer Communications Society (CHCCS/SCDHM) Achievement Award and the 2025 Mitacs Innovation Award for Outstanding Research Leadership. He has served on the Editorial Board of the ISPRS International Journal of Geo-Information (IJGI) since 2019.
