An introduction to accuracy testing of 1:1000 scale maps of Malta

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.
