GELE Surveying (Geomatics) — Vertical (Parabolic) CurvesSlides
Slide deck for GELE Surveying (Geomatics) — Vertical (Parabolic) Curves. These slides are built for quick visual review, highlighting the key concepts, formulas, and question patterns from this chapter of the GELE 2026 syllabus.
Exam context
Professional Regulation Commission (PRC) — Board of Geodetic Engineering runs the Geodetic Engineer Licensure Examination on September 2026. Its Surveying (Geomatics) section sits under a "Core" weighting, and Vertical (Parabolic) Curves is the 7th chapter in the 9-chapter GELE Surveying (Geomatics) rotation. The GELE passing mark is 70% weighted average, no sub-test below 50%, and the most recent 2026 paper drew about a meaningful share of questions from Surveying (Geomatics).
