CEG2728 : Geospatial Data Analysis II

  • Offered for Year: 2022/23
  • Module Leader(s): Dr Ciprian Spatar
  • Owning School: Engineering
  • Teaching Location: Newcastle City Campus
Semester 2 Credit Value: 10
ECTS Credits: 5.0


The module aims to develop advanced mathematical skills for understanding and undertaking the processing and analysis of geospatial data, including the identification and removal of outlying measurements. Students are provided with multiple case studies of least squares estimation applied to horizontal networks, coordinate transformations and GNSS pseudorange positioning.

Teaching Rationale And Relationship

Early lectures describe computations of horizontal control schemes, including networks in which distance and angular observations are jointly processed. Later lectures introduce outlier detection, network simulation and GNSS pseudorange positioning using the method of least squares. The theoretical concepts presented in lectures are augmented by case studies. Practical sessions allow students to apply the underlying theory with the aid of both spreadsheet applications and a specialised software package. Extensive time is allocated to independent study, which includes background reading and the revision of lecture materials.

Should the public health situation require, all present-in-person sessions will be delivered as synchronous online sessions. If necessary, the end-of-semester summative examination will be converted to a 24-hour take home examination delivered via the Canvas learning management system.

Assessment Rationale And Relationship

The majority of factual and conceptual material relating to the learning outcomes is assessed within the unseen exam. The two coursework reports assess the practical skills of students and the ability to present, describe and compare numerical results in writing. The two reports also assess the use of spreadsheet and specialised software applications for various least squares computations.
