Raster GIS Analysis for Global Landscape Sustainability

• The Global Landscape Sustainability project was conducted during my Ph.D. Postdoctoral studies with Dr. Ruth DeFries at the Ecology, Evolution, and Environmental Biology (E3B) Department of Columbia University.  I collected a variety of raster and vector datasets and modeled them into a global geodatabase developed for the project.  

 

• The picture composite shown below illustrates the results of a multitemporal data quantification analysis conducted to examine the expansion and distribution of cropland and pasture areas around the world.

​

• The entire series contains a total of 58 time frames which cover distinct periods of development.  The selected nine frames below show the range of landscape change that occurred between 2000 BC to 2005 AC

​
