Course Description

Introduces basic surveying techniques to landscape sites. Includes topographic maps and land divisions. Covers measuring, recording, and interpreting site information needed in the design and construction of landscapes. Prerequisites: LAT 236 or department permission. Audit available.

Addendum to Course Description

Students will learn through outdoor labs the use of level/transits and laser levels to a degree suitable for landscape measurements. Drafting experience or coursework is helpful, but not required.

Intended Outcomes for the course

Upon completion of the course students should be able to:

  • Understand the concepts of accuracy and precision and how to apply them to a given project€™s requirements.
  • Accurately use surveying equipment to obtain horizontal and vertical measurements to understand the slope of a site and draft a topographical map.
  • Use computation to measure, record and interpret site information to draft a site plan for use in design and/or construction of the landscape.
  • Read and interpret grading plans, using concepts of cut and fill to set grade stakes in the field.
