7th Annual CNY ASPRS New York State Remote Sensing Symposium

Detecting and Monitoring Land Use and Land Cover Change Over Time

The purpose of this course is to introduce students to the concepts and techniques of change detection.  Two primary questions are answered:

• How should change in land cover and land use be characterized?
• What types of GIS and remote sensing procedures can be used to locate, identify, measure, and incorporate change into land cover and land use applications?

The Workshop is organized as follows:

• Introduction
• Definition of change detection
• Discussion of the different goals of change detection

• Types of change detection procedures commonly used.

• Tabular comparisons
• Map to map comparisons
• Multi-temporal image analysis
• Manual and automated methods for change detection
• Single date analysis
• Multiple date analysis
• Image differencing
• Unsupervised classification of multi-temporal imagery
• Principal components analysis
• Map to image analysis
• Requirements of  change detection projects
• Specifying the type of change to be detected
• Choosing the source data
• Controlling all non-change variation

Each section of the workshop will be exemplified with real world case studies and applications.
