About

You will be able to

  • Explain the meaning, need and classification of map projections
  • Construct cylindrical projections - simple cylindrical, cylindrical equal area and Mercator
  • Construct conical projections - one standard parallel, two standard parallels and Bonne's
  • Construct polar zenithal projections - equidistant, equal area, gnomonic and stereographic
  • Represent relief by contours and draw serial and cross profiles

Who it is for

  • B.A Geography students of Semester 2 (UP state universities, NEP 2020 syllabus)
  • Students who need guided practice for the practical record and exam

What you need

  • Geometry box, scientific calculator or trigonometric tables, drawing sheets and practical file
  • Cartography Practical-I (scales) completed

Questions

Which syllabus is followed?

The NEP 2020 common minimum syllabus of UP state universities. Where your university's list of projections differs, the centre follows your own university syllabus.

Do I need to learn trigonometry?

Only simple values of sin, cos, tan and cot are needed; the trainer shows the calculation table for each projection.

How is the practical marked?

Each sheet is checked for correct calculation, construction, labelling and neatness, as in the university practical exam.
