1. Investigating Land Cover Change In Crow Wing County Emily Smoter and Michael Palmer Remote Sensing of Natural Resources and the Environment University of Minnesota

2. Investigate and quantify percent land cover change in Crow wing County from 1985 to 2006. With a special interest in the Brainerd area. Brainerd is a major tourist destination. Crow Wing County's population has increased by ~20,000 people from 1985-2006. Brainerd's population has increased by 2,100 in the same amount of time With population increases and higher levels of tourism, we will expect to see an increase in urbanization, and overall loss of undeveloped land around Crow Wing County and the Brainerd area. Project Objective

3. Increased development Wildlife Habitat loss Water infiltration Concerns o Runoff due to increases in impervious surfaces Implications of High Density Urban Land Cover

4. Area of Interest Crow Wing County Minnesota 1157 sq/miles

10. Accuracy Assessment Overall Accuracy: 78.10 % Kappa Statistic: 0.724

11. Limits of Classification

12. Comparison and Analysis Comparing Percent Change in Cover Type Class from 1985 to 2006

13. Conclusion Analysis of land cover change confirmed that high density development increased by 138 percent. High density development increased around large lakes Density of Brainerd & surrounding area increased Agriculture, grassland, and low density rural decreased
