2. Topographic mapping: according to the design requirements, measure the strip topographic map near the road on the spot;
3. Midline survey: set the road position on site according to the design requirements;
4. Drawing of longitudinal and cross-sectional drawings: measure the ground undulation in the direction of road centerline and perpendicular to the centerline, and draw longitudinal and cross-sectional drawings;
5. Construction survey: According to the design requirements and construction progress, various pile points will be released in time as the construction basis.

Road Engineering Survey is a book published by People's Communications Publishing House in May 1, 2065438. The authors are Tang and Zhao Xin speed skaters.
This book is a textbook for curriculum reform in national demonstrative higher vocational colleges. Based on the survey process of road engineering construction, this book analyzes and combs the knowledge structure, professional skills and comprehensive quality of survey tasks in three stages of road engineering construction, and constructs six projects in the learning field of Road Engineering Survey.
They are: elevation control survey, plane control survey, local topographic mapping, road centerline survey, road centerline survey and road cross-section survey. This textbook combines practical engineering cases, implements the combination of work and study, fully embodies the vocational education concept of taking students as the main body and cultivating students' professional ability, and is refined in content, practical and operational.
