2026 Understanding Engineering Design and GIS Symbols Webinar

Fee: $30/Member; $45/Nonmember

~Fee includes .1 CEU and access to recorded video for 60 days following the webinar.

Parks and recreation projects rely heavily on engineering drawings and GIS data, yet many professionals have limited exposure to the symbols and conventions used in these systems. This session, led by experience trail planner and owner of Penn Trails, Sarah Walter, explains the core elements of engineering design and GIS symbology, and participants will learn how to interpret plan sets, construction drawings, and GIS layers by breaking down line types, contour markings, utilities, grading indicators, and asset-mapping icons. Build the confidence to communicate effectively with engineers, review project documents, and make informed decisions throughout planning, design, and construction.
