COURSE AND CURRICULUM DEVELOPMENT (All Years) GEOG 211 Geography of Environmental Systems Lab (1) CORE/USP

University of Maryland Instructional Improvement Award (2001). Dr. Dubayah received a grant, along with a department contribution, to fund a TA and purchase new equipment for the creation of new labs and the revision of several existing labs. In addition, approximately 4 years ago, Dr. Dubayah worked with Dr. Prince to create new laboratory exercises for this class along with an accompanying published exercise manual. Exercises are now uniformly split between indoor and outdoor lab activities including mapping, soils, climate and hydrology. Indoor labs make use of state-of–the-art technology including remote sensing and geographic information systems (GIS). Lastly, Dr. Dubayah initiated an optional field trip for all students examining the physical geography of Maryland and offers this each semester he teaches the class (the trip requires the instructor’s attendance on both a Saturday and a Sunday due to the number of students in the course). 2007 – Addition of one new lab on Climate Change.


GEOG 345 Climatology (3)

This class was updated to provide a rigorous, quantitative survey of meteorology and climatology. New features include required weather forecasting exercises using on-line weather maps and imagery, extensive problem sets, and a required term project where students must track the daily weather at a particular city for the entire semester and write a report on the factors influencing the weather for the season.

GEOG 448 Field Techniques in Environmental Science (3) Dr. Dubayah revived this class in 1996, the first time the class had been offered in 5 years, and the first time it had been taught in a field camp setting in over 15 years. The class was revised again in 2001. The class was in residence for 10 days at Monongahela National Forest, West Virginia. Fieldwork covered vegetation sampling, topographic mapping, geology and geomorphology, hydrology, and water resources (including stream channel profiling and stream flow measurements), and soils analysis using a variety of specialized techniques and instrumentation. New field exercises were created for 2001, including the use of state of the art GPS, GIS, and remote sensing resources, coupled with field lap top computers. Field camp also included invited experts in botany, hydrology, and soils from the University of Maryland, the U.S. Geological Survey and NASA, who stayed overnight at the camp and participated in the teaching. Class was significantly upgraded in 2005, with particular emphasis on field computer mapping techniques. Class was further updated in 2007 to include in depth soil science and water quality monitoring.

GEOG 606 Quantitative Spatial Analysis (3) This course was completely revised to cover advanced topics of modern spatial analysis and statistics, including lectures and exercises on linear and multiple regression, principal components and factor analysis, spatial autocorrelation, point pattern analysis, analysis of area data, geostatistics and Fourier (spectral) analysis, time series and autoregressive models, trend surface analysis, classification and regression trees. Course also included extensive instruction in UNIX and the Splus statistical package. Lectures were redesigned to include integrated, real-time, on-line demonstrations of statistical analyses using a laptop and projector during class.


GEOG 609B Seminar in Lidar Remote Sensing (3) This was a new offering that reflected the need to instruct graduate students in the new area of lidar remote sensing, given the development of the Vegetation Canopy Lidar mission by Dr. Dubayah. The course was a combination of lecture and seminar and included hands on work by the students with real lidar data and a significant term paper/project. Lectures covered the basis of lidar remote sensing in different applications, as well as a review of the VCL mission. Several outside experts were also brought in to present material to the students. Student response to the class was enthusiastic as it brought together important scientific issues with cutting-edge technological solutions to those issues, and informed the students as to the immediate significance of lidar and the VCL mission.

HONRS299P Observing the Earth from Space

This was a new undergraduate Honors seminar. The course covered the use of remote sensing in earth system science. The course also covered in depth the science, technology and engineering of the Vegetation Canopy Lidar mission. The class was a mixture of lectures and guest speakers and included an all-day field trip of canopy measurements, as well as field trips to NASA/GSFC to see the VCL instrument and Orbital Sciences Corporation to visit the VCL Spacecraft. Note that the class also met part of the Educational Outreach requirement of the VCL mission to NASA.
