GIS for Environmental Applications
Textbook Exam Questions
Course Introduction
This course introduces students to the fundamentals and applications of Geographic Information Systems (GIS) in environmental science. Through a combination of lectures and hands-on tutorials, participants will explore spatial data collection, management, analysis, and visualization techniques relevant to environmental studies. Key topics include environmental mapping, land use and land cover analysis, habitat assessment, and spatial modeling for natural resource management. By the end of the course, students will have practical experience using GIS software to address real-world environmental challenges, enabling them to interpret and communicate spatial data in research and professional contexts.
