Research assistantship available in remote sensing analysis

Graduate Research Assistant or Project Assistant, Remote Sensing of Urban and Peri-Urban Expansion

The Land Cover Change Lab at the Center for Sustainability and the Global Environment (SAGE) has funding for one RA or PA position starting this fall, and continuing through spring and summer, 2015, to conduct research to monitor urban expansion and agricultural land loss across East-Southeast Asia using multiple remote sensing data sets.

The overall goal of the project is to monitor land cover change, and work will be completed using a combination of ENVI, ArcGIS, and command line programming tools.  The student will focus on analysis of time series MODIS satellite data to understand global trends in urban expansion.  For more information, please click here.

Application deadline: October 27, 2014

New article now in press at Remote Sensing of Environment

Check out our recent research Detecting change in urban areas at continental scales with MODIS data in this upcoming issue of Remote Sensing of Environment.  This work, completed as part of Carly Mertes' Master's thesis, demonstrates a methodology for monitoring urban land expansion at continental to global scales using Moderate Resolution Imaging Spectroradiometer (MODIS) data.  The new method focuses on resolving the spectral and temporal ambiguities between urban/non-urban land and stable/changed areas by: (1) spatially constraining the study extent to known locations of urban land; (2) integrating multi-temporal data from multiple satellite data sources to classify c. 2010 urban extent; and (3) mapping newly built areas (2000-2010) within the 2010 urban land extent using a multi-temporal composite change detection approach based on MODIS 250 m annual maximum enhanced vegetation index (EVI).  The method is tested in 15 countries in East-Southeast Asia experiencing different rates and manifestations of urban expansion.

New results on peri-urbanization in Vietnam

Our research, Monitoring peri-urbanization in the greater Ho Chi Minh City metropolitan area, was recently published in Applied Geography.  This research combines commune-level Vietnamese census information, dense time stacks of Landsat satellite data (1990–2012), and several spatial measures to quantify urbanization and peri-urbanization in the greater Ho Chi Minh City metropolitan area from 1990 to 2012. The results indicate that 660.2 km2 of cropland was converted to urban uses (a near quintupling of urban land), while 3.5 million persons moved into the region, bringing the total population to nearly 12 million by 2012. The analysis also highlights the rapid, unplanned nature of peri-urban development: approximately one-third of new urban expansion occurs in areas >40 km from the core, with nearly 50% of population expansion occurring in communes classified as peri-urban.  Check out the full article at this site: http://www.sciencedirect.com/science/article/pii/S0143622814001477.

New NASA funding to understand land cover change teleconnections

Annemarie Schneider and collaborators received a NASA grant for their project Forest, agricultural, and uban transitions in Mainland Southeast Asia: synthesizing knowledge and developing theory. The project is designed to enhance the conceptual underpinnings of land change science by integrating aspects of land teleconnections, land use transitions, and political ecology to explicitly link land changes in SE Asia to local, national, and international drivers. The work will study transitions in forests, boom crops, and periurban areas using remote sensing imagery, socioeconomic data, focus group discussions and surveys designed to harness local knowledge.
