This research seeks to explore the meaning of Technology in Landscape Architecture (TLA) as part of Landscape Architecture (LA)'s body of knowledge. It will investigate TLA and its emerging specializations, along with related core domains and associated topical areas. This exploration will also examine the inter-relationships of DTT and research methods within the landscape research as a way to analyze the meaning of TLA and its significance on 21st century LA core domains. In this study context, this research will draw from three realms of knowledge: (1) Digital Tools and Technology (DTT) in LA; (2) LA Core Domains; and (3) Trends, Themes and Priorities in LA Research. This research proposes a mixed methods approach with the exploratory goal to gain a deeper understanding of the meaning of TLA, its specialties and ways it intersects with the core knowledge domains within the LA discipline. This study on TLA will also be comprehensive in its examination of both contemporary scholarly research and professional practice including current trends and themes. The significance of this research demonstrates ways technology has evolved as its own significant domain where the discipline of LA has shifted from the art-science binary narrative to an emergent 21st century conceptual tri-partite core consisting of art, science and technology.
