These maps are crucial for planning, design, estimation, and construction decisions. Diploma holders need to understand different surveying methods and equipments. They should also be skilled in using and operating them. The course is designed to help diploma holders efficiently conduct surveys using equipments like Chain/tape, Theodolite, Total Station, Handheld G.P.S., etc. They will acquire skills in measuring dimensions, computing areas and volumes, and creating precise drawings, strengthening their practical knowledge and field expertise. | . ## Course Outcome: After Completion of the Course, the students will be able to: | No | Course Outcomes | RBT Level | |------|---------------------------------------------------------------------------------------------|-------------| | 01 | Carry out theodolite traverse survey, compute necessary data, and draw traverse. | R, U, A | | 02 | Conduct contour survey for undulating/hilly regions using a Tacheometer and draw contours. | R, U, A | | 03 | Set out a horizontal curve using a theodolite. | R, U, A | | 04 | Conduct a traverse survey using a total station and demonstrate a Hand-Held GPS. | R, U, A | *Revised Bloom's Taxonomy ( RBT ) ## Teaching and Examination Scheme: | Teaching Scheme (in Hours) | Teaching Scheme (in Hours) | Teaching Scheme (in Hours) | Total Credits L+T+ (PR/2) | Assessment Pattern and Marks | Assessment Pattern and Marks | Assessment Pattern and Marks | Assessment Pattern and Marks | Total | |-------------------------------|-------------------------------|-------------------------------|--------------------------------|--------------------------------|--------------------------------|--------------------------------|--------------------------------|---------| | L | T | PR | C | Theory | Theory | Tutorial / Practical | Tutorial / Practical | Marks | | L | T | PR | C | ESE (E) | PA (M) | PA(I) | ESE (V) | Marks | | 02 | 00 | 04 | 04 | 70 | 30 | 20 | 30 | 150 | w.e.f. 2024-25 http://syllabus.gtu.ac.in/ Page 1 of 5 ## GUJARAT TECHNOLOGICAL UNIVERSITY ## Program Name: Engineering ## Level: Diploma ## Branch: Civil Engineering ## Course / Subject Code: DI03006021 Course / Subject Name: Advance Surveying ## Course Content: | Unit No. | Content | No. of Hours | % of Weightage | |-------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-----------------|-------------------| | 1 | Theodolite Traverse: 1.1 Introduction to theodolite, Uses of theodolite, Sketch and parts of Transit Vernier theodolite. 1.2 Reading of main and vernier scale on horizontal and vertical plate. 1.3 Temporary adjustment of a theodolite. 1.4 Permanent adjustment of theodolite (Fundamental axis of theodolite and their relationship). 1.5 Definitions and various technical terms. 1.6 Methods of measuring horizontal angles and vertical angles. 1.7 Use theodolite to measure a magnetic bearing, prolong a line, and range a line. 1.8 Measuring direct and deflection angles. 1.9 Errors in theodolite work. 1.10 Theodolite Traversing. 1.11 Traverse computations, closing errors, Balancing the traverse. | 07 | 23 | | 2 | 1.12 Gale's Traverse Table & Related Examples.
