SVI 553: Hydrographic Surveying Field Practical

The Department of Surveying and Geoinformatics has a working arrangement with the National Inland Waterways Authority (NIWA) Lokoja, Kogi State to use their facilities for hydrographic practical. The field trip is usually embarked by 500level students accompanied by 3 or 4 staff of the Department. The objectives of the trip includes: i) positioning in the high seas with GPS, ii) Echo sounding-bathymetric survey (seabed profile), iii) reduction of readings to required datum and (iv) plotting of the bathymetric survey plan/chart.

At the end of the practical exercise, the students are exposed to practical knowledge of hydrographic surveying and are assessed through their technical report submitted at the end of the trip.

 

SVI 535: Photogrammetric Field Practical using UAV

The practical exercise will focus on the use of unmanned aerial vehicle (UAV) to acquire aerial photographs. Processing of the photographs using the available software and presentation of results.

 

 

 

  • Photogrammetry and Remote Sensing Lab. Practical

200 Level: Photo-pointing, Manual measurement of photo-coordinates, stereoscopy and parallax. Use of parallax bar and mirror stereoscope, stereoscopic measurement of parallax and ground heights from parallax measurements.

300  Level: Interior, relative and absolute orientation of photographs using analytical/Digital methods. Measurement of photo-coordinates with stereocomparator. Solution of collinearity and coplanarity condition equations. Projective transformation in absolute orientation. Single photo resection and plotting from single photographs.

400  Level: Computation of model deformations. Plotting from stereo models, manual interpretation of satellite images. Digital image processing (DIP). Image classification and computer spatial pattern recognition.

500  Level: Conversion of analogue photographs to digital. Photgrammetric processing of digital aerial photographs (radiometric correction, enhancement, automatic point identification / image matching and orientations ) Digital Terrain modelling and production of autophotomaps. Remote Sensing applications.

SVI 500: PROJECT SEMINAR

This seminar usually consists of aspects of students’ final year projects. It is expected that every student will present an oral seminar consisting of at least the first three chapters of the degree project report in the first semester of the final session. The three chapters will be arranged as a proposal to cover 1. Introduction, 2.Literature Review and 3.Methodology.

 

SVI 500: DEGREE PROJECT

The Degree project shall consist of well designed field or laboratory – based work. The project topics are designed to span through the basic branches of Surveying and Geoinformatics and are meant to expose students to theoretical, practical and laboratory approaches in Surveying and Geoinformatics.
