C.M. Bliss, Soil and Water Science Department, University of Florida

Dataset

Soil properties/horizon, topographic data and water table measurements collected

at 123 wells, over a 5-year period (1992 – 1998), on a 42-ha flatwood landscape

33 km northeast of Gainesville

Methodology

Employ 2D and 3D ordinary kriging to reconstruct 3D soil-landscape models and

to utilize the Virtual Reality Modeling Language (VRML), External Authoring

Interfaces (EAI), eXtensible 3D (X3D), and Java for space-time modeling and

visualization of dynamic properties (e.g. water table dynamics)

Objectives
