Our program is approved by the Alabama Board of Licensure for Engineers and Land Surveyors, so you can be assured your TROY degree can lead you to a career as a licensed land surveyor in Alabama. To become a professional licensed land surveyor, you must apply through the Alabama Board of Licensure for Professional Engineers and Land Surveyors. For more information, visit bels.alabama.gov.
The subdiscipline of land surveying is an ancient science dating back to the first need to delineate land ownership on the ground. The need for land boundaries or cadastral surveyors is just as important today. In fact, one could argue that as human population grows, the demand for the fixed quantity of land on the earth surface increases. As land values increase, the need for the accurate determination of land boundaries becomes even more important.
Many geomatics professionals assist in the design and construction of roads, bridges, subdivisions and planned unit developments. Areas of interest are planning and zoning, the principles of route surveying, hydrology, large-scale mapping, subdivisions design and CAD drafting.
Students are offered the opportunity to study land development in GEM 4405 Route and Construction Surveying, GEM L407 Land Development Lab and GEM 4409 Hydrology. Topographic mapping is studied in GEM 3330 Advanced Measurement Analysis and GEM L405 Route and Construction Surveying Lab. GEM 4409 is a design course focused on the determination of peak flows and design of hydraulic flows to accommodate runoff. An exciting integration of land development and GIS is offered by new software that offers parcel management features.
GPS is a complex system that is easy to use. However, to understand the system itself, one needs to study the propagation of electromagnetic waves (microwaves), the properties of the atmosphere, the orbits of the satellites and the impact of solar radiation, the concept of precise timing, the ellipsoid model used as a reference system for GPS measurements, transformations between coordinate systems and the principles of least squares adjustment.
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 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:
GIS is an application that can benefit from the input of a team of interdisciplinary professionals. A geomatics professional is a valuable member of a GIS team when the mapping data is required to be precise such as the base map for county land ownership or utility location. Applications requiring precise data typically use photogrammetry and survey-grade GPS receivers to acquire the data.
Simply put, a GIS combines layers of information about a place to give you a better understanding of that place. One of the main benefits of GIS is improved management of your organization and resources. A GIS can link data sets together by common locational data, such as addresses, which helps departments and agencies share their data. By creating a shared database, one department can benefit from the work of another.

The Surveying/Geomatics program provides the student with instruction in survey theory and fundamentals for both office and field practice. The goal of the program is to prepare students for entry level employment into the land surveying profession. There are numerous specialties in survey employment, and early counseling is suggested to help select the proper optional classes.
Recommended High School Preparation: Courses in algebra, trigonometry, physics, and geography.
The Surveying/Geomatics Associate in Science (A.S.) degree may be obtained by completion of the required program, plus general education requirements, plus sufficient electives to meet a 60-unit total. See SCC graduation requirements.
