Geography  609B is a seminar on the theory and application of lidar remote sensing and laser altimetry for characterization of the land surface.  Lidar is potentially a breakthrough technology for measurement of the three dimensional structure of the Earth's forests, topography, ice sheets and waters.  The planned deployment of the Vegetation Canopy Lidar Mission, the ICESAT Mission, Shuttle Laser Altimeters, as well as recent advances in airborne laser altimetry and lidar imaging will open a new era of remote sensing.

 

 

Course Format:

 

The class will be in a seminar format.  Reading and web materials will be assigned each week that will form the basis of the next week’s discussion. There will be several guest experts in lidar who will present material and lead discussions. The class will meet most, but not, every Thursday during the semester (see the table below). Note that there will be an all day field trip in September in place of Thursday classes. There will be a class website, as well a class email list. All information will be exchanged via the website and email, so its important to check these frequently.

 

 

Course Requirements:

 

Regular class attendance is required for a seminar class.  Students will be assigned specific readings and expected to lead a discussion on those readings (probably in groups). There will be one or two assignments using actual lidar data. Students will have a choice of either writing 4 critical abstracts of the class readings in a particular area, or, a final project, the form of which will be determined later (e.g. development of web materials, analysis of lidar data, critical review of a selected topic, etc). Final grades will be determined from all of the above.
