PHOTOGRAMMETRY AND REMOTE SENSING
|
| |
| The U.S. National Map Program providing full map coverage of the
continental United States was made possible by the development of
the theory and practice of photogrammetry. Photogrammetry is the science
of obtaining measurements from photographs. Today the importance of
photogrammetry has not diminished as the most effective method of
providing precise spatial data over large project sites. The pressing
need for precise spatial data for Geographic Information Systems makes
the field of photogrammetry an exciting area to study. |

| Students are taught the fundamentals of photogrammetry with an emphasis
on being able to apply photogrammetry in a practical way to all types
of surveying and mapping problems. Troy University has made an investment
in leading-edge imaging software to allow students to use computers
to view photography, perform image enhancement, set-up stereo-models,
and to produce orthophotos to use as maps. Our students are taught
how to perform aerial flight planning to ensure the photography and
control necessary to meet specific project data accuracy requirements.

| Students are exposed to the following technology: |
| |
- SUMMIT EVOLUTION digital photogrammetric workstation: This is
a user-friendly system for performing 3D feature collection directly
into AutoCAD®, MicroStation®, or ArcGIS®. The SUMMIT
EVOLUTION system allows for easy management of multiple model
images along with their appropriate camera and control files in
a project-based environment.
- ERDAS IMAGINE is one of the world's leading provider of geographic
imaging solutions. The software facilitates visualizing, manipulating,
analyzing, measuring, and integrating any type of geographic imagery
and geospatial information into 2D and 3D environments. ERDAS
IMAGINE is easily integrated with ArcGIS®
