A landform in the earth sciences and geology sub-fields, comprises a geomorphological unit, and is largely defined by its surface form and location in the landscape, as part of the terrain, and as such, is typically an element of topography. Landform elements also include seascape and oceanic waterbody interface features such as bays, peninsulas, seas and so forth, including sub-aqueous terrain features such as submersed mountain ranges, volcanoes, and the great ocean basins.

Landforms are categorised by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure, and soil type.

Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas and numerous other structural and size-scaled (i.e. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features.

Oceans and continents exemplify the highest-order landforms. Landform elements are parts of a high-order landforms that can be further identified and systematically given a cohesive definition such as hill-tops, shoulders, saddles, foreslopes and backslopes.

Stan Allen is an American architect, theorist and dean of the School of Architecture at Princeton University. He received a B.A. from Brown University, a B.Arch. from the Cooper Union and an M.Arch. from Princeton University and has worked in the offices of Richard Meier and Rafael Moneo. He was formerly the director, with landscape architect James Corner, of Field Operations. His practice, Stan Allen Architect, is based in Brooklyn.

Responding to the complexity of the modern city, Allen has developed an extensive catalogue of urbanistic strategies, in particular looking at field theory, landscape architecture and ecology as models to revitalize the practices of urban design. His urban projects have been published in Points and Lines: Diagrams and Projects for the City (New York: Princeton Architectural Press, 1999) and his theoretical essays in Practice: Architecture, Technique and Representation, published in 2000 by G+B Arts in their Critical Voices series. A revised edition of this book was published in 2009 by Routledge. He lectures and publishes extensively, both in the U.S. and abroad, and participates in numerous international design conferences and symposia.
