Railroad track is the backbone of a railway network and a key element of the vehicle-track system. Its primary functions are to support and distribute train loads, guide rail vehicles and facilitate drainage. This course covers a wide range of technical subjects: the theory and the practical application of track engineering principles, advanced track structure analysis (both static and dynamic) and innovative track technologies and modeling and simulating different track structures. Further more, it explores the interaction with other modules such as hydrology, bridge, sub structure (subgrade). The module will combine theoretical analysis with practical applications to allow students to understand how railway engineering and operational principles are used in the real world.
This module is designed to introduce students to the concept and design of hydraulic structures. Latter being anything whether fully submerged or partially submerged, that can be used to control water flow velocities, directions and depths, the elevation and slope of the stream bed. This module introduces to them the general configuration of waterways including their stability and maintenance characteristics. A weir, for example, is a type of hydraulic structure that can be used to pool water for irrigation, establish control of the bed (grade control) or, as a new innovative technique, to divert flow away from eroding banks or into diversion channels for flood control. The shape, size and other features of a hydraulic structure can vary widely for different projects, depending upon their functions. Hydraulic design procedures must govern the final design of all structures. This module will introduce the students to understand the basic principles of river engineering, and design of diversion works and cross-drainage and drop structures.

Welcome to the module Cadastre & Land Administration II.
This Module is the expansion of Cadastre & Land Administration I. It introduces concept of boundary in title surveys that supports land registration and defining international territorial boundaries.
This course provides the fundamentals needed to understand the application of hydraulics to civil engineering works. The course covers application of the principles of fluid mechanics to flow in open and closed channels. It introduces to students the basic concepts of irrigation and drainage systems: design, planning and management; particularly the design of irrigation and drainage projects. Thereafter the course intends to provide the students with understanding of the importance of water supply systems in society and with a good understanding of water demand estimation, design of water supply system including storage capacity and appurtenances of water network.
This module welcome students for an intuitive approach to GNSS positioning will be presented as an introduction to GNSS. The course introduces basic principles and technologies as well as outlines some of the applications of Global Navigation Satellite System (GNSS). It also covers GNSS history and evolution as a Geomatic technology. It focuses on point positioning techniques as it applies to static and detail surveys.
In this module, we will move a step further and learn how to make more sense of the landscape by dividing it into separate classes based on surface characteristics. This process is known as image classification. It involves conversion of raster data into finite set of classes that represent surface types in the imagery. It may be used to identify vegetation types, anthropogenic structures, mineral resources, etc. or transient changes in any of these features. Additionally, classified raster image can be converted to vector features (e.g., polygons) in order to compare with other data sets or to calculate spatial attributes (e.g., area, perimeter, etc). Image classification is a very active field of study broadly related to the field of pattern recognition. In this unit, we will discuss about different image classification methods, signature evaluation and the guidelines for selecting a classification method.
In this module, you will studied about the elements and keys of image interpretation, techniques of ground truth data collection and characteristics of digital remote sensing images. Proper knowledge of all these concepts is required to extract precise and accurate information present in remotely sensed images. The module, comprising four units, introduces you to various aspects of digital image processing and interpretation such as image correction, enhancement, transformation, classification and accuracy assessment.
Unit 1 deals with errors present in the images such as radiometric and geometric errors and their corrections. Necessary corrections are required in order to correct the raw data transmitted from satellites to ground stations. In this unit, you will learn how images are corrected before they become suitable for practical applications.
Unit 2 introduces you to image enhancement and transformation techniques which greatly increase the visibility of features contained in the images. You will learn about the image enhancement and transformation techniques such as contrast stretching, image filtering, image fusion and vegetation indices.
Unit 3 deals with various aspects of image classification. You will study about the transformation of an image into a thematic map based on spectral response of image features. We will be discussing various methods of image classification such as supervised and unsupervised in this unit.
Unit 4 discusses fundamental concepts, needs and methods of accuracy assessment. You will study more about the sources of errors, sampling size, error matrix and also importance of assessing quality of map products generated from remote sensing data.
Objectives
After studying this block, you should be able to:
- Discuss major distortions of remotely sensed data and process of their corrections;
- Explain techniques employed for enhancement and transformation of remotely sensed data;
- Describe image classification methods and choose an appropriate image classification technique for a specify study; and
