Land Use/Land Cover Assessment of Dane County,
Wisconsin: Contemporary Trend and Future Projections
By Eric Fabian
Introduction
• Research Question: What will the future land use and land cover be by 2030 in Dane County, Wisconsin? • Objective: To assess current land changes and predict future trends• Human-Environmental and Spatial Tradition• Remote Sensing Concept
Concepts and Traditions
• Human-Environmental and Spatial Tradition• Human impact combined with remote sensing for assessment• Remote sensing and GIS algorithms used to predict change
Data
• Landsat Imagery• Classified LULC Images• Lidar Data• Census Block Group Data• Income Data
Classified Imagery
Object-Based Classified Images showing urban land, forested land, agricultural land, and water bodies
Lidar Data

Types of Census Data
• Population Data used as “driver” to predict future trend• From 2000 and 2010• At block group level for accuracy
• Income Data• From 2000 and 2010
Methodology
• Creation of two classified images using eCognition object based classification• Creation of multiple secondary classes through a combination of
ArcMap and Erdas Imagine Software• Implementation of TerraSync Prediction Software using drivers like
center of Madison, Wisconsin, distances to major roads, population change, income change
Preliminary Discussion
• Increase of urban land from 2000-2010 signifies continued increase for future• Decrease of forested land from 2000-2010 signals possible continued
loss to 2030.• Continued population growth• Policies in place steering trends
