Contributions to Geographic Information Science

Mark's specialty was in the field of Geographic Information Science (GIScience). He authored or coauthored more than 230 scholarly papers which have been cited over 10,000 times.^[6] He researched cognitive and linguistic foundations of how geographic information is conceptualized and used. In the 1970s and 1980s, he pioneered methods for representing topography for digital computers, including the earliest methods for the Triangular Irregular Network data model. He is credited for a popular water flow routing GIS algorithm, which specifies how to eliminate spurious pits from digital elevation models.^[7] In 1990, David Mark organized with Andrew U. Frank the NATO Advanced Study Institute in Las Navas del Marquez (Spain).^[8] This meeting was the origin of research in spatial cognition and linguistics for the field of GIScience. With Barry Smith and others, Mark co-authored several widely cited papers on geographic categorization, geographic reasoning, and the ontology of geographic features.^[9][10] In the early 2000s, Mark and Andrew Turk created the area of study called "Ethnophysiography" to study how language and culture are related to people's naïve conceptualizations of the physical landscape.^[11] Until his death, he continued to work on most of these topics, with special focus on establishing a foundational ontology of the landscape.
