Photogrammetry is a science based technology with more then a century of history and development, it can be defined as the ‘science of measuring from photos' and it's part of the field of remote sensing (RPL551). The techniques used in photogrammetry allow us to extract quantitative data from aerial and satellite imagery; in comparison to extraction of qualitative data form airphoto interpretation (GRY360). Thus by using photogrammetry you can determine the size and height of a house in a set of stereo aerial photographs and by using photo interpretation techniques you can asses the style of the house allowing you to determine when the house was constructed. The goal of the Digital Photogrammetry and GIS course (GRY552) is to show students how photogrammetry works through 'learning by doing'. Each year the class undertakes ‘real world' projects and problems, the students are encouraged to come up with their own solutions based on the knowledge they gained in the lecture component of the course. Below are the GRY 552 class projects, listed by year:

In 2006 six class projects were undertaken:

• Springfield Land Change Analysis Project by Corey Brunk
• James River Dam Area Change From 1953 to 2003 by Jason Whitsett
• Amateru Anaglyphs by Rob Farnsworth
• New High School building proposal for Carthage, MO by Michael Montague
• Can survey quality measurments be derived from a terrestial photograph using simple photogrammetric techniques? by Jeremy Thomas
• Applying photogrammetry to track poverty migration by Steve Johnson

In 2005 two class projects were undertaken:

• The Missouri State Univeristy-Mountain Grove Campus Mapping Project – based on the success of the 2004 Springfield Campus Mapping Project and the CNAS Centennial Project, students will be developing an interactive map for the Missouri State Univeristy Mountain Grove Campus.

• The Tumbling Creek Cave Historic Land Use/Land Cover Change Mapping Project – the project is directly related to the iCAVE (interactive Cave Animation Visualization and Exploration) Project sponsored by the James River Basin Partnership.

In 2004 the class worked on one project:

• Mapping and 3D visualization of the Missouri State Univeristy-Springfield Campus – the mapping was done from 1995 black and white stereo aerial photography, in addition the students captured some of the buildings on campus using ground based stereo photography. The project contributed to the CNAS Centennial Project.
