Abstract. The goal of this research is to design, use and evaluate a set of weblectures, specifically tailored to the needs of students in higher education who follow GIS-related courses. Since education in GIS includes theoretical concepts and practical experience, these teaching strategies will both be implemented in the weblectures. The User Centered Design approach is used in the design process to increase the acceptance of the weblectures and the motivation to use them: perceived usefulness and ease of use. The results show that the students appreciate the initial set of weblectures, but that they need to be motivated more to use them (especially when theoretical topics are covered). Students still value the 'traditional' face-to-face lectures and see the weblectures as an ideal complement.
At the end of the 18th century, a large-scale map of the Austrian Netherlands and the Prince-Bishopric of Liège was manufactured, covering more or less the current territory of Belgium. The work for this Carte de Cabinet was carried out by artillerists under the guidance of count Joseph de Ferraris, who was commissioned for the task by the Habsburg government. At the time that the map was designed, no modern legend was included. This report tries to fill that gap by presenting a legend that was constructed more systematically than any of its predecessors. It is based on the structure of the legend of the Topographic Map of Belgium and the CORINE land cover map, making it an easy-to-use tool for modern researchers. The problems encountered during the development of the legend are described, and the link between the Carte de Cabinet and 18 th -century French cartography as well as with cartographic manuals is also discussed.
Wallington in central Northumberland is a late seventeenth-and early eighteenth-century country house with associated pleasure grounds. Much of the surrounding estate is agricultural land, though there are also expanses of moorland and conifer plantation. The character of Wallington's landscape, now divided into fifteen separate farm holdings, was to a large extent shaped by estate management practices and improvements in the eighteenthnineteenth centuries. Today's settlement pattern is made up largely of dispersed farmsteads, with field systems which reflect the orderly rectilinear layout of planned enclosure, being separated mainly by long and fairly straight stonefaced banks. In medieval and early modern times, by contrast, the landscape is thought to have been quite different, with nucleated villages set amidst irregular open fields which were farmed collectively.The process of long-term landscape change from open to enclosed field systems has been inferred across the whole of Northumberland but it can be difficult to understand in detail. Absolute dating evidence for field systems before the eighteenth century is generally lacking and the origins and development of historic earthworks including boundary banks and the remains of arable farming are poorly understood.This paper presents results of research which used retrogressive landscape analysis (based on documentary evidence, archaeological data, aerial photographs, and historic cartography) to identify five areas for detailed geoarchaeological investigation and sampling with optically stimulated luminescence profiling and dating (OSL-PD). The results provide new perspectives on the development of landscape character at Wallington which have wider relevance for north-east England and beyond.

The accuracy of old maps can hold interesting historical information, and is therefore studied using distortion analysis methods. These methods start from a set of ground control points that are identified both on the old map and on a modern reference map or globe, and conclude with techniques that compute and visualise distortion. Such techniques have advanced over the years, but leave room for improvement, as the current ones result in approximate values and a coarse spatial resolution. We propose a more elegant and more accurate way to compute distortion of old maps by translating the technique of differential distortion analysis, used in map projection theory, to the setting where an old map and a reference map are directly compared. This enables the application of various useful distortion metrics to the study of old maps, such as the area scale factor, the maximum angular distortion and the Tissot indicatrices. As such a technique is always embedded in a full distortion analysis method we start by putting forward an optimal analysis method for a general-purpose study, which then serves as the foundation for the development of our technique. Thereto, we discuss the structure of distortion analysis methods and the various options available for every step of the process, including the different settings in which the old map can be compared to its modern counterpart, the techniques that can be used to interpolate between both, and the techniques available to compute and visualise the distortion. We conclude by applying our general-purpose method, including the differential distortion analysis technique, to an example map also used in other literature
