Landmarks are crucial elements of human understanding of and communication about space. And they pose a major challenge for computational systems.
Stephan Winter and I have written a book — Landmarks – GIScience for Intelligent Services — summarizing research on integrating (references to) landmarks into computational systems from the last decade or so. It covers cognitive, conceptual, computational, and communication aspects and argues why producing and understanding landmarks is a necessity for truly intelligent geospatial systems.
The book is published by Springer.
I sure know what we did last summer…
