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.

Automatic Transcription of Geographic Names: A Cartographic Implementation 地理名称的自动转录:一种制图实现
IF 2 Q3 REMOTE SENSING Pub Date : 2003-06-01 DOI: 10.1080/00690805.2003.9714230

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.
地名在地图学中的重要性使得相关的标准化问题确实具有决定性。这种情况在所谓较少使用的语言中尤为明显。希腊字符的制图使用仅在两个小国(希腊和塞浦路斯)实施,这一事实在将地名抄写为罗马字符时造成了不适。2004年希腊奥运会给这个问题带来了新的维度。将希腊地名抄写成罗马文,在制图方面也越来越重要。在这里,一个简单的有效的自动转录系统已经开发出来,它不仅可以用于制图目的,也可以用于一般相关的文本和图形应用。

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.
本文考察了尼日利亚的测绘情况。在这个国家有许多组织参与测绘活动,这些组织可以分为公共和私营部门,联邦调查局是最高的测绘组织。总的来说,这个国家的地图绘制得很差,地图绘制产品的范围和质量就说明了这一点。这是由于经费不足,造成测绘人员和设备目前的状况。对测绘工作进行了详细的评价,并讨论了如何改进我国的测绘工作。

A Comparison of Inverse Distance Weighting and Ordinary Kriging for Characterising within-paddock Spatial Variability of Soil Properties in Western Australia 西澳大利亚围场内土壤性质空间变异性的逆距离加权与普通克里格法比较
IF 2 Q3 REMOTE SENSING Pub Date : 2003-06-01 DOI: 10.1080/00690805.2003.9714231

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)
因地制宜的作物管理需要将资源应用和农艺实践与土壤和作物需求相匹配,因为它们在田地内因空间和时间而异。因此,关于农场或围场规模的土壤成分的信息是必不可少的。整个围场的土壤成分可能不均匀。例如,如果只有东北角出现缺陷,那么对整个围场进行施肥可能效率不高。此外,不可能对围场的每一厘米都进行采样,因为这将是一个非常耗时和昂贵的过程。理想情况下,我们应该能够收集足够的样本点,以便使用空间插值技术准确地生成土壤属性的连续图,并且可以对整个围场的土壤成分做出良好的判断。本文比较了两种空间插值方法——克里格法和逆距离加权法(IDW),评价了它们在围场水平季节性稳定土壤性质预测中的准确性。由于Yule等人(1996)和Brady和Weil(1999)之前的研究发现,有机质含量和土壤反应(pH)是本次调查选择的土壤特性,这些特性与种植潜力相关。选择的空间插值器在现有数据集(例如100个土壤样本)上进行测试,这些数据集是在西澳大利亚西南部一个60公顷围场上使用分层随机方法收集的。研究方法包括三个主要步骤。首先,应用基本的描述性统计技术来识别异常值的存在。其次,利用所选插值器生成土壤属性的连续图,最后以均方根误差(RMSE)作为验证指标,对所选土壤属性选择最佳空间插值器。因此,对于每一种土壤性质,从主数据集中抽取每四分之一的样本,并将其搁置,以验证插值方法的结果。同样,使用克里格插值方法生成的不确定性图被用作评估预测图质量的附加来源。RMSE结果表明,IDW对pH(例如0.38 vs 0.39)和有机质(1.25 vs 1.34)的表现略好于克里格法。

Developing A Spatial Model Of Probable Hiking Experiences Through Natural Landscapes 通过自然景观建立可能徒步旅行体验的空间模型
IF 2 Q3 REMOTE SENSING Pub Date : 2002-12-01 DOI: 10.1080/00690805.2002.9714208

The natural landscape is an arena for a wide array of recreational activities. Recent changes in hiking behaviour in wilderness settings have been attributed to changes in tourists' attitudes, personalities and life styles. Modern tourists are not only looking for quality but also a variety of leisure products and experiences and a style of product delivery compatible to their life style. Tourists patronise those areas that offer diversity of natural and cultural attractions and a variety of experiences in an easily legible, navigable and accessible geographic space. This paper investigates characteristics of terrain surfaces in order to develop a spatial model of hiking experiences around the Pinnacle walking track in the Grampians National Park. In situ measurements of feelings and experiences were determined via a questionnaire administered to a group of adolescent aged students hiking on a track. The paper shows the development of a set of predictors derived from surface features and surface cover that can be used to predict potential hiking experience. Factor analysis has been used to identify a smaller set of dimensions that explain most of the variance among input variables. Finally, a predictive spatial model of hiking landscapes has been developed from input maps over the entire geographic space. The developed spatial model of probable hiking experiences is suggested as an alternative strategy to ease mounting pressure around existing walking tracks.
自然景观是各种娱乐活动的场所。最近在野外徒步旅行行为的变化归因于游客的态度、个性和生活方式的变化。现代游客追求的不仅仅是品质,还包括丰富的休闲产品和体验,以及与他们的生活方式相适应的产品交付方式。游客光顾那些在易于辨认、通航和无障碍的地理空间中提供多种自然和文化景点和各种体验的地区。本文研究了格兰屏国家公园尖峰步道周围的地形特征,以建立徒步旅行体验的空间模型。通过对一组在轨道上徒步旅行的青少年学生进行问卷调查,实地测量了他们的感受和经历。本文展示了一套基于地表特征和地表覆盖的预测因子的发展,可用于预测潜在的徒步旅行体验。因子分析已经被用来确定一个较小的维度集合,解释了输入变量之间的大部分差异。最后,基于整个地理空间的输入地图,建立了徒步旅行景观的预测空间模型。开发的可能徒步旅行体验的空间模型被建议作为缓解现有步行路径周围日益增加的压力的替代策略。

This paper investigates characteristics of terrain surfaces in order to develop a spatial model of hiking experiences around the Pinnacle walking track in the Grampians National Park. In situ measurements of feelings and experiences were determined via a questionnaire administered to a group of adolescent aged students hiking on a track. The paper shows the development of a set of predictors derived from surface features and surface cover that can be used to predict potential hiking experience. Factor analysis has been used to identify a smaller set of dimensions that explain most of the variance among input variables. Finally, a predictive spatial model of hiking landscapes has been developed from input maps over the entire geographic space. The developed spatial model of probable hiking experiences is suggested as an alternative strategy to ease mounting pressure around existing walking tracks.","PeriodicalId":44129,"journal":{"name":"Geodesy and Cartography","volume":"36 10 1","pages":"102 - 87"},"PeriodicalIF":2.0,"publicationDate":"2002-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72945518","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Multimedia Cartography has changed artifacts for geographical exploration-from ‘frozenscapes’ (visualizations of geography that cannot be altered by the user) to ‘Malleable Visualizations’ (a computer-generated multimedia visualization with which users can interact and ‘mold’ into one that best suits their particular needs). However, it is argued, this has caused problems, as Multimedia Cartography is more complex. Does the way of ‘seeing’ influence the way of knowing? Does the application of interactive multimedia products really allow access to ‘better’ educational packages? What is the most appropriate pedagogy for using New Media technologies for geography education? How do humans learn geographic information, and how does this learning vary as a function of the medium through which it occurs (direct experience, maps, descriptions, virtual systems, etc.)? This paper reports on the initial findings from the ‘GeoExploratorium’ research programme, that investigated the construction and evaluation of a ‘different way’ of offering geographical teaching/learning elements with multimedia cartography. The ‘GeoExploratorium’ provides a new way of ‘seeing’ geographical information by supplying different viewpoints, hopefully, ensuring that the ‘voids of geographical understanding’ are filled with information gathered from other perspectives and used to assemble a more complete picture of reality.
多媒体制图已经改变了地理探索的人工制品——从“冰冻景观”(用户不能改变的地理可视化)到“可塑可视化”(一种计算机生成的多媒体可视化,用户可以与之交互并“塑造”成最适合他们特定需求的可视化)。然而,有人认为,这引起了问题,因为多媒体制图更复杂。“看”的方式会影响认识的方式吗?交互式多媒体产品的应用真的能让人们获得“更好”的教育内容吗?使用新媒体技术进行地理教育最合适的教学方法是什么?人类是如何学习地理信息的,这种学习又是如何随着学习媒介(直接体验、地图、描述、虚拟系统等)的功能而变化的?本文报告了“地理探索馆”研究项目的初步发现,该项目调查了利用多媒体制图提供地理教学/学习元素的“不同方式”的构建和评估。“地理探索馆”通过提供不同的观点,提供了一种“看到”地理信息的新方式,希望确保“地理理解的空白”被从其他角度收集的信息所填补,并用于组装一个更完整的现实画面。
