This section will describe about the industrial training where students have to fulfill the diploma needed for subject SUG 394. The practical was going on at Innovative Mapping Solutions SDN BHD where the works done are related with remote sensing and GIS. The practical was going on from 1st June 2010 until 1st October 2010.

1.3Background of the Project

The title for this project is “Land Use Classification Map of Kuala Perlis Using SPOT 5”.

1.3.1Aim and Objectives

The aim of this project is to produce a land use map of Kuala Perlis for SPOT 5 in 2005.

The objectives are stated as follows:

i) To perform unsupervised classification for study area. ii) To generate a land use map of a study area based on unsupervised classification.

1.3.2Study Area

The study area of this project is Perlis. The state covers a total area of over 810 km2 (312.7 sq mi). It is cover the area of Kuala Perlis. Almost all the states are filled with the vegetation area which is paddy field. Kuala Perlis is the second largest town and the main port of Perlis in Malaysia. It is in extreme northwest Peninsular Malaysia, near the border with Thailand.

1.3.3Scopes of Work

The scopes are:

i) Study Area

The study area was carried out at Perlis where the images for the study are using SPOT 5 satellites images. The focus area is Kuala Perlis, Perlis.

ii) The availability of the Data

The year covered for this project is from year 2005. The images were getting from Malaysian Remote Sensing Agency (MRSA).

1.4Organizations of Chapters

In conclusion, this chapter covers the background of the company where the practical was done, the background of the study and scopes of the work for this project. Chapter 2 covers about the literature review that involves in this project. Chapter 3 covers about the methodology involves in this project where the methods and flow can be seen in this chapter. Chapter 4 discuss about the result and analysis get from the study while Chapter 5 covers the conclusion for this project.




This chapter will review about the theoretical over remote sensing and the theory and concept of work that had been undertaken in this project. In this chapter also explain about the satellite was produce the image during doing this project.

2.2Remote Sensing

Remote sensing can be defined as the science and art of obtaining information about an object, area, or phenomenon through the analysis of data acquired by a device that is not in contact with the object, area, or phenomenon under investigation (Thomas M. Lillesand and Ralph W. Kiefer, 1994).

In remote sensing, there are some process that involves an interaction between incident radiation and the targets of interest. Figure 2.1 below show elements of remote sensing process.


Figure 2.1: Elements of remote sensing

From the figure above, the energy source from the Sun or illumination (A) provides electromagnetic energy to the target of the interest (Earth). Before the energy reach to the Earth, the energy source will travels from the source (Sun) to the target where it will contact and interact with the atmosphere it passes through. This is called Radiation and the Atmosphere (B).

When the energy reaches to the Earth or target, it will interact with the target (C). Then, the energy that reaches to the target will be recorded by the sensor (D). The sensor will collect and record electromagnetic radiation of the energy. A sensor is characterized by its spectral properties (number and placement of bands), its orbital altitude and path, its swath width, and its spatial resolution. SPOT, Landsat and more tends to utilize polar-orbiting satellites with medium spatial resolution (5 – 30 meter). There is more explanation about SPOT 5 in the next topic. However, there are...
