Poliorkitou 37 546 33 Thessaloniki Greece kostas@maplibrary.gr Abstract The importance of toponymy in cartography makes the relevant standardization issue indeed decisive. This is particularly the case in the so-called less spoken languages. The cartographic use of Greek characters is implemented only in two small countries (Greece and Cyprus), and this very fact is creating discomfort in practicing transcription of geographic names to Roman characters. The occasion of the 2004 Olympics in Greece has given the issue a new dimension. The transcription of Greek place names into Roman is gaining relevance also as far as the cartographic implementation is concerned. Here, a simple system for an effective automatic transcription has been developed, which can be used not only for cartographic purposes but also in general relevant text and graphical applications. A Comparison of Inverse Distance Weighting and Ordinary Kriging for Characterising Within-paddock Spatial Variability of Soil Properties in Western Australia T P Robinson G Metternicht   Department of Spatial Sciences Curtin University of Technology GPO Box U 1987 Perth WA 6845   Abstract Site-specific crop management requires matching resource application and agronomic practices with soil and crop requirements, as they vary in space and time within a field. As such, information on the composition of soils at either farm or paddock scale is essential. Soil composition over an entire paddock might not be uniform. For instance, it may not be efficient to fertilise an entire paddock if only the northeast corner show deficiencies.  Furthermore, it is not possible to sample every centimetre of the paddock, as this would be a very time consuming and costly procedure.  Ideally, we should be able to collect enough sample points so that continuos maps of soil properties can be accurately produced using spatial interpolation techniques, and good judgements can be made about the soil composition of an entire paddock.   Two spatial interpolators, namely kriging and inverse distance weighting (IDW) are compared in this paper, evaluating their accuracy in the prediction of seasonally stable soil properties at paddock level.  Organic matter content and soil reaction (pH) are the soil properties selected for this investigation, as previous research by Yule et al. (1996) and Brady and Weil (1999) has found these properties to be correlated to cropping potential.     The selected spatial interpolators are tested on an existing data set (e.g. 100 soil samples) collected using a stratified random approach over a 60 ha paddock, located in the southwest of Western Australia.  The research approach consists of three main steps.  Firstly, basic descriptive statistical techniques are applied to identify the presence of outliers.  Secondly, selected interpolators are applied to generate continuous maps of the soil properties, and finally the mean root mean square error (RMSE) is used as the validation index, and to select the best spatial interpolator for the soil properties selected.  Therefore, for each soil property, every fourth sample is removed from the main data set and put aside to validate the result of the interpolation method.  Likewise, the map of uncertainty generated by using the kriging interpolation method is used as an additional source for evaluating the quality of the prediction maps. The RMSE results show IDW to perform slightly better than kriging for pH (e.g. 0.38 vs 0.39) and organic matter (1.25 vs 1.34 ) Operational Infrastructure For Quality Distance and Online Geospatial Programs   K McDougall F R Young A Apan Faculty of Engineering and Surveying University of Southern Queensland TOOWOOMBA. QLD.  4350 mcdougak@usq.edu.au youngf@usq.edu.au apana@usq.edu.au   Abstract The Surveying and Land Information Discipline at the University of Southern Queensland (USQ) has delivered full time and distance education programs in surveying and related areas for over 26 years.  Academics at USQ have recently embarked on multimedia enhancement and online delivery of curricula to provide an even broader and more contemporary learning environment.  These enhancements, when developed professionally, require a significant commitment of resources and expertise, and often necessitate a team approach to their design and development.  Although there has been a proliferation of activity in the area of online delivery, little consideration has been given to the support infrastructure that is necessary to establish, deliver and maintain these offerings.  This paper examines the operational infrastructure that is critical to distance education students receiving a comprehensive, timely and quality learning experience. The Current Trend of Mapping in Nigeria   R O Olomo   Department of Geography and Regional Planning Ambrose University PMB 14 Ekpoma  NIGERIA   Abstract This paper examines the mapping situation in Nigeria. There are many organisations that are involved in mapping activities in the country, these can be classified into the public and private sectors, with the Federal Survey Department as the apex mapping organization. Generally, the country is poorly mapped as exemplified by the range and quality of mapping products.  This is attributed to poor funding, which is responsible for the current state of mapping personnel and equipment. A detailed evaluation of mapping and how to improve mapping in the country is discussed.   Contemporary Cartography Paper   Internet GIS Development For Educational Purposes    A. Vassilopoulos N. Evelpidou   Remote Sensing Lab., Geology Dept., University of Athens Panepistimiopolis, Zografou, 157-84, Athens, Greece   vassilopoulos@geol.uoa.gr evelpidou@geol.uoa.gr   Abstract Geographical Information Systems (GIS) are important tools for various scientific aspects. Especially sciences related to cartography and geographical analysis should definitely employ GIS technology.     In this study an Internet–based GIS is presented that was developed on the MapXtreme platform. This application gives access to numerous web-users through a server that controls both analysis and data retrieval requests.     It is a practical and economical method in order to introduce GIS to educational institutions. This Web GIS may operate through a local or wide area network and, apart from educational purposes, offers a low cost information exchange solution between vast numbers of users.
