Summer Job Opportunity Developing forest stewardship plans as part of the statewide forest resource assessments • Requires using geospatial technologies (learned in this class) • Can be counted for internship credit • $10 / hour • Need 4 to 5 people • Here on WVU campus • Start as soon as possible • Flexible work schedule • Contact Steve Harouff at steven.e.harouff@wv.gov
Final Exam Review FOR 326 Spring 2009
Final Exam • Monday May 4th in this room • 3 to 5pm • Format (100 possible points) 10 true / false (1 point each) 10 multiple choice (2 points each) 10 short answer questions (3 points each) 8 longer answer questions (5 points each) • Covering lectures, exercises, readings • No calculator needed
Things to keep in mind • Not a trivia test • Understand basic concepts • Major topics will dominate the test • Be able to integrate concepts to real world decisions or applications • If I gave you the same test six months from now …
Lecture topics • Intro to geospatial technologies • Geospatial technologies in forestry • Spatial data and mapscale • Mapscale detail and projections • Electromagnetic energy and spectral properties • Photo properties and principals • Land use and cover mapping
Topics cont’ • Vegetation mapping • Terrain analysis • Hydrological applications in forestry • LiDAR • Classification techniques • Accuracy assessment • GPS • 3D visualization and modeling
1. Intro to geospatial technologies • What are geospatial technologies and why do we need to know about them?
2. Geospatial technologies in forestry • What are some ways in which geospatial technologies can aid foresters do their job? • What are some things foresters should consider or understand before using geospatial technologies?
3. Spatial data and mapscale • How would you explain what is spatial data? • How is mapscale important in the planning of a particular project?
4. Mapscale detail and projections • How is map detail related to mapscale? • What are projections? • How concerned do I need to be about projections when managing a project with spatial data?
5. Electromagnetic energy and spectral properties • Why can we see what we see? • Why would we want to use a filter or lens to see infrared? • How do we interpret a spectral reflectance curve? • What are some adv and disadv of both color and color infrared film for use in forestry applications?
6. Photo properties and principals • Why is a photo not a map? • How should a flight plan be designed to capture all of the features on a property? • Why is it possible to see overlapping aerial photos in 3D?
7. Land use and cover mapping • Why is the USGS land use and land cover mapping scheme so necessary? • What is the difference between land use and land cover? • How do we decide the process to assign or classify the many land use and cover classes?
8. Vegetation mapping • What makes identifying individual tree species with remote sensing so difficult? • Explain how you would use a classification guide to aid in vegetation mapping. • What are some of the ways we can improve our prediction of vegetation species?
9. Terrain analysis • What dataset is needed for terrain analysis? • What other datasets can be derived from it? • How is terrain important to foresters?
10. Hydro applications in forestry • Why is it important to understand the hydrological properties of a forest treatment site? • What are some of the ways in which GIS and hydrological analysis can aid in proper forest management? • What are main datasets need to perform hydrological analysis?
11. LiDAR • What is it? • How does it work? • What can a forester use it for? • Comparison to other elevation data
12. Classification techniques • Who needs to extract information from an image? • What are some ways to extract information from an image? • What role does field work have in image classification?
13. Accuracy assessment • Why do we care how well an image is classified? • In general, how do we find out how good or bad an image was classified? • What is acceptable?
14. 3D visualization and modeling • Besides a pretty picture, what purpose does 3D visualization have for a forester? • What are some analysis capabilities available for 3D work? • What makes 3D visualization possible?
15. GPS • How accurate is the average GPS? • How accurate does a forester need GPS to be? • What are some things to consider when using a GPS unit?
