2. Import raw surveying data for development of surfaces and topographic drawings.
3. Create a digital terrain model for an existing site.
4. Create alignments, profiles, and cross sections for roadway projects.

Course Activities and Design

Lecture, discussion, demonstration and lab sessions will be the instructional methods used in this course. Individualized instruction
will be provided during class time while the student is working on assigned projects. Open lab time will be available, if needed to
complete assigned projects.

Outcome Assessment Strategies

Evaluation will be based on the accuracy and completeness of projects, worksheets, and tests. Procedures for evaluation will be discussed
during the first class meeting.
