PLSCS/NTRES 6200: Spatial Modelling and Analysis

Intended for early-stage MSc and PhD students, and final semester undergraduates, who are using some kind of spatial or spatio-temporal analysis in their thesis projects.

Theory and practice of applying geo-spatial data for resource inventory and analysis, biophysical process modeling, and regional studies. Emphasizes use and evaluation of spatial analytical methods applied to agronomic and environmental systems and processes. Laboratory section is used to process, analyze, and visualize geo-spatial data of interest to the student, ending in a student project linked to the student’s on-going or proposed thesis/exit project research.

SCAS 494: Land Suitability Evaluation

Land evaluation may be defined as the process of prediction of land performance when the land is used for specified purposes.

This course was last given in 1994; it is thus somewhat outdated but still can be a useful starting point. Algunos capítulos se han traducidos al Español.
