CEG3711 : Map Projections and Datums for Engineers

Semester 2 Credit Value: 10
ECTS Credits: 5.0


The aim is to introduce students to the concepts required for working with data on the curved surface of the Earth and its plane map projections, in geodetic surveying, remote sensing, GIS and engineering applications.

Outline Of Syllabus

Analysis of data
Revision of normal distribution, sample means and confidence limits
Statistical testing, sampling distributions,
Examples using F test, t test and chi-squared test.

Spherical and ellipsoidal computations
Plane projections: Developable surfaces, classification of projections
Map projection scale and use of rescaling
Cylindrical projections: Equii-distant, equal area and Mercator
Transverse Mercator and UTM
Azimuthal projections
Conical projections: Lambert projection
Working with projections: convergence, line scale factor, arc-to-chord correction
Introduction to datums

Teaching Rationale And Relationship

Specialist knowledge, understanding and skills are primarily imparted by lecture classes, supported by focussed practical sessions; students are encouraged (through a structured reading list) to learn through independent reading. Key skills are further supported by practicals along with specific coursework submissions which allow the student to demonstrate their ability to report on and synthesise practical work.

Assessment Methods

The format of resits will be determined by the Board of Examiners

Practical/lab report2M303 practical write-ups plus further calculations (approx 6 hrs for each). Each worth 10% of the total module assessment.
Assessment Rationale And Relationship

Practical write-ups will demonstrate the student's ability to perform statistical testing, the fundamental skills associated with map projections and the ability to work with map projections in usage in the UK. The written exam will cover the knowledge and synthesis of the lecture material.
