Environmental Studies Speaker Series featuring presentation by Dr. Chunzeng Wang
Nadeau Hall Conference Room
Time: 11:00 AM - 12:00 PM
Location: Nadeau Hall Conference Room

Chunzeng Wang, PhD. Associate Professor in Earth and Environmental Sciences at the University of Maine at Presque Isle

Presentation Title: “High-precision Land-cover-land-use GIS Mapping for Land Potential Assessment Based on High-resolution Aerial, CIR, and LiDAR Data in Agricultural Northern Maine”

The event is free and open to the public

Talk summary: This talk presents a high-precision land-cover-land-use GIS mapping project and its application in land potential assessment in central Aroostook County. The project is part of Maine’s SSI EPSCoR project conducted at UMPI. It used integrated on-screen digitization and direct interpretation of high-resolution multispectral imagery and LiDAR data, supplemented by a ground-truthing method. The project not only provides the first-ever high-precision land-use maps for northern Maine, but also yields accurate estimates of different land-use types, in particular grass lands, defined as fallow land, pasture, and hay fields. This enables land potential assessment and land availability and suitability analysis. The analyzing results show that central Aroostook has an ample base of suitable, underutilized land for producing grass biomass or for other sustainable land uses.

Dr. Wang's Bio: Chunzeng Wang was trained to be a geologist with his bachelor’s (1984 from Guilin College of Geology) and Master’s (1989 from China University of Geosciences) degrees in China. While pursuing his second Master’s (2000) and doctorate (2001) degrees in Earth and Environmental Sciences at the Graduate Center of the City University of New York, he broadened his interest into GIS and applications of GIS technology in geology, natural resources, environment, and infrastructures. After moving to Aroostook County and starting his current job at UMPI in 2005, he immediately launched UMPI’s GIS program from scratch and built a state-of-the-art GIS laboratory with external funds. Dr. Wang is an active research geologist and works on a number of geological research projects supported by U. S. Geological Survey and China’s National Natural Science Foundation in Maine and China and has authored/co-authored more than 40 peer-reviewed articles. He has developed a community GIS partnership with central Aroostook cities, towns, and major non-profit organizations. Each year, he and his students work on community-related GIS mapping projects. Two examples of the projects are the non-motorized trail mapping project http://( and the Fairmount cemetery mapping project http://(

The Environmental Studies Speaker Series presentations are open to the public and cover such topics as water quality, waste management, wind power, endangered species, forestry, and marine science. The program is offered in collaboration with the UMFK Environmental Studies degree program. Speakers are only scheduled during the academic year.
