Abstract: Metadata is data about data. In an organisation that is amassing a growing store of spatially referenced information a need, if not a demand, for information about this geographic data should be considered. The scope of a metadata base is the cataloguing and description of spatial data sets and making this information available to users in a data directory of geographic information. The aim of this dissertation is to construct a basis from which a working Geographic Information Data Directory can be adapted for the Planning Authority. This was achieved by examining current international trends and standards for metadata and identifying the core functions and information needs of the Planning Authority. The organisation's geographic data sets where examined and a data model of the core spatial information resources was constructed using classic data modelling techniques. Identifying and compiling metadata for each data set extended the data model to create sufficient data documentation as the basis from which a Geographic Information Data Directory can be constructed.

Abstract: It has been concluded from this project that the 1: 1000 scale maps of Malta produced by the Mapping Unit are very close to the range of the accuracy standards established by the Ordnance Survey of Great Britain. This does not mean that there is no room for improvement, in fact the recommendations at the end of this project will encourage and guide the unit for the introduction of accuracy testing so that it can achieve better accuracy in its products. After a brief description in the introduction about the objectives of the project, one can find in chapter two some definitions of relevant terms used in the process of the accuracy test. Chapter three gives a brief picture about the process of photogrammetry for map compilation. The study will proceed with an amount of data and information collected for interpretation. Chapters four and five go into detail about the type of test adopted and the statistical calculations that were used in the process. Further statistical analysis needs to be done to substantiate the results achieved from this type of test. This study is intended to achieve a horizontal metric quality assurance for the digital maps. It is important that the sample checks are carried out on regular basis and that the recommendations given in chapter six are taken into consideration by the officer that will be in charge of doing future tests.

Abstract: Since I joined the Planning Authority in October 1995 I was assigned to the Mineral and Planning Unit One of the problems that stirred my interest was the increasing problem of Inert Waste Disposal in Malta. With my work I hope that in some way I will help to leviate this problem and eliminate illegal dumping of waste in the environment.
Objective of the project: As a result of quarrying activity there is the existence of a large number of sites which may be suitable for filling with inert waste. This provides the opportunity for landfilling and restoration of the land to a beneficial after use such as agriculture. This project is concerned with the formulation of assessment criteria for quarry sites suitable for filling with inert waste in Malta and Gozo. The plan, although specific, will provide an example of the construction works needed, and operational procedures to be followed in the development of a management plan for one of the sites. This can also be applied to the other selected sites.

Abstract: The scope of this study is to recommend some changes in the current procedures when processing the 1: 1000 map which is issued by the Mapping Unit, Planning Authority. Having experience in processing both the 1 :2500 map and the 1: 1000 map, helped in making comparisons, where possible, between the two procedures, enabling me to arrive to the desired recommendations. In the first chapter, some technical details, regarding aerial photographs and their interpretation in photogrammetry are introduced. This chapter is going to be useful to the reader as background information for the following chapters, and also to be able to position himself behind the stereo-plotter and understand the problems that may arise in data capturing. In fact, data capturing, as it is done at the Mapping Unit, is discussed and analysed in chapter two. This chapter take us through various stages; from ground control to actually plotting the data, and also discusses what features are being plotted and how. The following chapter, that is chapter three, goes through the process of the editing work done on the raw data after it is passed on from the photogrammetry section, as it is currently being done by the section. As one would notice, the process is a long one, having to go through site checking, editing the necessary data until finally the survey sheet is issued. Some changes that need to be implemented in the present process of the 1: 1000 mapping are described in chapter four. Changes are recommended at various stages of this process, such as photogrammetry, site checking and editing work These changes are derived from interviews made to some of the staff at the Mapping Unit. Two primary recommendations are discussed in detail in chapter five. If these are implemented, the 1:1000 map should be more consistent and faithful to the user, and more useful to both the Mapping section and its clients. Maps are included throughout this report to aid the reader in visualising the current problems and appreciate the recommendations made and the results which are achieved in this study.
