Abstract
Nowadays the rapid advances in digital imaging sensors and scanners, computer modeling and multimedia technologies, as well as the availability of many powerful graphics PCs and workstations make new methods for digital documentation of buildings feasible. Digital documentation with 3-d modeling functionality is a new term in architecture and engineering, supporting documentation extensions for e-learning (pedagogically functionality) and meta-documentation (vastness data and meta-data for historical living systems functionality)• which are introduced to literature for the first time within this paper. In particular, such a methodolgy must be able to derive pictorial, geometric, spatial, topological, learning and semantic information from the target architectural object (historical building, monument), in such a way that it can be directly used for e-learning and meta-documentation purposes regarding the history, the architecture, the structure and the temporal (time-based) 3-d geometry of the projected object. A practical project is used to demonstrate the functionality and the performance of the proposed methodology. In particular, the processing steps from image acquisition to the 3-d geometric and semantic description of the St. Achilleios basilica, lake Prespes, Northern Greece in a CAAD model are presented. Also, emphasis is placed on introducing the new terms e-learning & meta-documentation functionality as functionality extensions to proposed digital documentation method. Finaly, comparisons of cost and relative disadvantages of other methods of documentation are examined, and for documentation and learning purposes related to 3-d modeling, a comparison of the results for images taken by a digital solid-state sensor camera and a metric film-based one is carried out and presented.

Personalized e-Learning Implementation - The GIS Case

Athanasios D. Styliadis, Ioannis D. Karamitsos, D. I. Zachariou

Abstract
Personalized e-learning implementation is recognized as among one of the most interesting research areas in the distance learning Web-based education. In particular, the GIS e-learning initiatives that incorporate —by default— a number of sequencing spatial techniques (i.e. spatial objects selection and sequencing), will well benefit from a welldefined personalized e-learning implementation with embedded spatial functionality. This is the case addressed in this paper.
The GIS e-learning implementation introduced in the current paper is based on a set of teaching (lecturing) rules according to the cognitive style of learning preferences of both the learners and the lecturers as well. It is important to note that, in spite of the fact that most of these teaching rules are generic (i.e. domain, view and user independent), there are no so far well-defined and commonly accepted rules on how the learning spatial GIS objects and techniques should be selected and how they should be sequenced to make “instructional sense" in a Web-based GIS course.

Abstract
Representations used in digital documentation applications today usually assume a world that only exists in the present. Information contained within a database may be added-to or modified over time, but change through time is seldom maintained. This limitation of current IT has recently received attention, given the increasingly urgent need to understand geographical processes and cause-and-effect inter-relationships between human activities and the environment. Models proposed for the representation of spatio-temporal data are extensions of traditional raster and vector representations that can be seen as location- or feature-based, respectively, and are therefore best organized for performing, either location- or feature-based queries. In this paper, a new spatio-temporal data model suitable for digital documentation of historical living systems (artefacts, monuments and sites) is defined: it is based on 3-D geometry and intended to facilitate analysis of temporal relationships and patterns of 3-D modeling changes through time. This is particularly useful to both IT and IS managers, researchers and practitioners. It is shown that time-based queries related to 3-D models of objects can be processed in an efficient and straightforward manner using the model. Finally, analytical time efficiency estimations are given, showing that the model is also an efficient and compact representation of spatio-temporal information.

Personalized e-Learning in a Re-Usable Way:
A Proposed GIS System Design – The Architecture

Athanasios Styliadis, Konstantinos Pehlivanis
Department of Information Technology, The ATEI of Thessaloniki

ABSTRACT
For e-Learning, learning objects and XML not only present advanced technologies, but also promise an approach to create online instruction quickly and economically. Although it is unlikely that a global library of learning objects, which follows some open standards, will be formed in near future, developing a campus-wide instructional system based on learning objects for courseware design and delivery is still possible. The main goal of this research is to develop a reusable and adaptive e-Learning system with XML schemas forming the basic framework. This system shows that it is possible to achieve flexibility, reusability, interoperability, and personalization of learning content in such a XML environment.
This paper describes the detailed design of the e-Learning system. The first section describes the architecture of this system. The second section deals with the design of the Learning Management System.

Abstract
This paper presents an evaluation procedure for the educational material, written exercises and face-to-face meetings in the module ‘Educational Research’ in the Hellenic Open University (H.O.U.). The study gives us helpful results for the educational services improvement, according to the students’ perceptions and needs.
The H.O.U. was founded in 1997. Since Greek students have no experience in e-Learning and Distance Education Institutions, it is important to find out if they are positively disposed towards adopting new ways and approaches in order to achieve educational goals. The systematic procedure of the data collection and interpretation that concerns particular system components is aiming at the feedback of the effort with useful information.
By identifying the needs of Greek distance learners of this course, we pointed out the necessity to recreate the printed material and increase the number of face-to-face meetings with academic staff.

Personalized e-Learning in a Re-Usable Way:
The Learning GIS Content Development

A/Prof. Athanasios D. STYLIADIS

ABSTRACT
E-learning content seems to be of more use to practitioners if it is delivered in small manageable chunks. This is particularly important when considering ways in which e-learning content may be applied for GIS teaching in secondary and tertiary education. Design guidelines need to be re-visited to consider the GIS learning object approach to content development. Development of e-learning content design specifications should be reflecting the need for small chunks of highly customisable and interoperable GIS learning with spatial teaching functionality.

ABSTRACT
E-Learning benefits will be heightened when e-learning is personalized. E-learning should be dynamically personalized to both groups and individuals. The same courses will be presented with different content variations to different virtual groups. As learners move through the content, the course content and flow will alter. For course designers, the idea of learning objects requires an immense change in thinking. Instead of looking at learning as a fixed linear progression, we must now look at learning as clusters of independent, stand-alone objects of knowledge. These learning objects should be dynamically selected and sequenced by computer agents to form an individually tailored course. In this paper, a set of XML schemas is introduced, that can be used as basic templates to wrap and tag reusable learning objects.

ABSTRACT
The e-Learning well known benefits will be heightened when the learning procedure is personalized. Hence, e-learning should be dynamically personalized to both groups and individuals and in this case the same “digital” courses will be presented with different content variations to different virtual groups. As learners move through the content, the course content and the flow procedure will alter. For course designers, the idea of learning objects requires an immense change in thinking. Instead of looking at learning as a fixed linear progression with a restricted functionality, the research has to look at learning as clusters of independent, stand-alone objects of knowledge. These learning objects should be dynamically selected and sequenced by computer agents to form an individually tailored course. In this paper - supported by The Archimedes 2-2-17 Initiative - a set of XML schemas is introduced, that can be used as basic templates to wrap and tag reusable learning objects with enhanced GIS functionality.
