Classics from IJGIS: Twenty years of the International Journal of Geographical Information Science and Systems

Spanning the 20-year history of the International Journal of Geographic Information Science (IJGIS), this reverential chronicle contains articles that shaped the way GIS is approached, provided the underpinnings of fruitful branches of development, and opened new avenues of discovery across the landscape of modern GIScience. Along with nearly every article is a commentary written by at least one of the original authors. In these commentaries, the authors reflect on what drove their original research, why the concepts were widely adopted (or in some cases, why not), and what future researchers can expect in the field. The final article examines the social networks that have evolved in the GIS community.
