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. I have taught this each Spring semester (in fact mostly winter weather) since 2012 until 2024. It will not be offered in 2025 because a new Professor of “Geospatial Science for Sustainable Land Processes and Management” (Prof. Yun YANG) has been hired, and does not need to teach in the first year at Cornell. Policy is not to continue a course with an Adjunct Professor (me) if there is a regular faculty who are supposed to cover the course. So with all its resources and despite always-excellent reviews, and a key place in the curriculum, the Spring 2025 students are out of luck. The course may re-appear in 2026, offered by Prof. Yang, who would undoubtably revise it according to her ideas. I might be asked to give a guest lecture but the current format will not be revived.

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.

2023 version: Laboratory section was 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.

For 2024 the course was cut down to a set of four Case Studies: (1) familiarity with the R “ecology”; review of basic statistical analysis; (2) Mapping regional climate by interpolation from point observations; (3) Central NY State Leukemia: areal spatial data analysis (ASDA); (4) Trees in Michigan, Wildfires in Spain: point-pattern analysis.

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This course was last given in 1994; it is thus somewhat outdated but still can be a useful starting point.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.

南京师范大学 (Nanjing Normal University)¶

Frontiers in Geographical Information Science¶

An eight-week course for first-year students in the GIS concentration) of the School of Geography (地理科学学院), four from me on mapping and four from Dick Brus on spatial sampling. My part uses parts of the above slides, but also (from 2020) emphasizes research skills.

Exercise: regional mapping of climate variables from point samples: Northeast China

University of Twente (NL)¶

Faculty of Geo-Information Science and Earth Observation

Geostatistics & Open-source statistical computing¶

Distance education course, equivalent to a full-time 3-week module, last given in 2015. Here are the lecture slides (including self-assessement questions) and the set computer exercises, a bit outdated but could still be useful. Most of the exercises use the Meuse soil geochemical dataset.
