Megan Garms signed up for the Center Scholars Program, a research experience for undergraduates that teams motivated juniors with GSCE scientists. She has been working with Dr. Izaya Numata (at right in picture) and, earlier, Dr. Mark Cochrane to use geospatial technologies to analyze the regrowth and development of forests in the Amazon Basin in areas where logging had occurred. Megan has worked up to 10 hours per week during the school year (SP17, FA17, SP18) and more hours last summer. An Honors student, Megan is graduating in May from SDSU with a BS in Wildlife and Fisheries Sciences and a minor in Animal Health. She will be pursuing a DVM at Iowa State University in the fall. Congratulations to Megan!
Megan presented her research project entitled "Assessing Dynamics of Secondary Forest in Southwestern Amazonia Using Landsat Time Series Data" at the Undergraduate Research, Scholarship, and Creative Activity Day (URSCAD) on April 3rd. Her poster abstract follows:
The goal of this project was to monitor and study the dynamics of secondary forests in the Amazon over 31 years using available satellite data. The activities involve 1) development of annual land cover maps using a decision tree classification technique; 2) assess the accuracy of land cover map products using high spatial resolution data; and 3) identify spatial and temporal changes of secondary forest areas, its ages throughout a 1985 – 2016 study period. Based upon the results from 3), potential implications of secondary forest dynamics for carbon cycle in the Amazon will be discussed.
Professor Michael F. Goodchild will give the 10th Virginia and J. Edward Holtry Distinguished Lecture in Geographic Information Science titled “Space and Place” at 6:00 pm on April 5, Great Hall, McCrory Gardens Education and Visitor Center. Dr. Goodchild is emeritus professor of geography at the University of California, Santa Barbara. He is also distinguished chair professor at the Hong Kong Polytechnic University and research professor at Arizona State University and holds many other affiliate, adjunct, and honorary positions at universities around the world. His research interests center on geographic information science, spatial analysis, and uncertainty in geographic data.
Drs. Roy and Huang attended the 2018 NASA Land Cover Land Use Change Spring Science Team Meeting and gave a presentation on their newly funded NASA research:
Roy, D.P., Huang, H., Boschetti, L., Zhang, H., Yan, L., Li, Z., Landsat-8 Sentinel-2 global burned area product Prototyping (Type II) to Production (Type 1), NASA Land Cover Land Use Change Spring Science Team Meeting, Gaithersburg Marriott Washingtonian Center (Rio), Maryland, April 3-5, 2018.
Dr. Tom Loveland will deliver the GSCE seminar at 11 am on March 15th in the Volstorff Ballroom of the Student Union (note the deviation from the usual seminar location). His talk will be entitled “An Insider's Perspective on the Evolution of the Landsat Program”. Dr. Loveland is a research geographer at the USGS Center of Earth Resources Observation and Science (EROS) in Sioux Falls and the co-director of the Geospatial Sciences Center of Excellence.
David Roy and members of his research group attended the first new (2018-2023) Landsat Science Team meeting and gave the following presentation:
Roy, D.P., Yan, L., Zhang, H.K., Li, Z., Huang, H., Egorov, A., Pathfinding near real time moderate resolution land surface monitoring: looking forward to an operational Landsat 9/10 Sentinel 2A/2B era, USGS-NASA Landsat Science Team Meeting, USGS EROS Center, Sioux Falls, SD, February 21-22, 2018.
