WebGIS in education

Abstract

Web-based GIS or WebGIS is powerful mapping and analytical functionality expressed within a web browser. Today, webGIS comes in many forms from consumer navigational maps to versatile location analytics tools that allow for user-directed analysis and content discovery. With nearly two decades of development history, webGIS tools are rapidly amassing strength, precision, and speed -in some cases, surpassing the capacities of basic desktop GIS applications. The inclusion of real-time data from sensor networks, social media, and the larger GIS community can extend WebGIS-based instruction to every learner. Because of the increased power and customization, webGIS can now better support learning standards-oriented content in the natural and social sciences. No longer is it necessary to teach learners how to use GIS before teaching the disciplinary content of interest. In this article, the growing educative role for webGIS, both conceptually, technically, and practically will be explored, including the new affordances (e.g. collaboration, real-time data, distributed data, BYOD support, and interface customization) and constraints (e.g. bandwidth, privacy, and user management) provided by GIS in a cloud-based platform. Finally, considerations for preparing for new and pre-service teachers of webGIS, including pedagogical and technical considerations, will be discussed -providing a broad vision of the future of webGIS and how learners and educators can best utilize and prepare for that future.
