GELE Surveying (Geomatics) — Route, Topographic and Modern SurveyingSlides
Presentation-style slides for Route, Topographic and Modern Surveying — the fastest way to cover the chapter if you are reviewing on your phone between classes or shifts. Covers everything Professional Regulation Commission (PRC) — Board of Geodetic Engineering tests on this chapter in the GELE Surveying (Geomatics) subtest.
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 Route, Topographic and Modern Surveying is the 9th 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).
