地图是地理的“第二语言”,是地理教学的重要媒体和工具。随着教育信息化的发展,地理教学越来越多地使用电子地图。电子地图不但可以表现比普通地图更多的信息量,而且可以非常方便地对普通地图的内容进行任意形式的要素组合、拼接,形成新的地图。随着网络技术和地理信息技术的发展,通过地理信息系统（GIS）和数字制图技术实现并依托于互联网等数字媒介的矢量化的电子地图正在成为地图的新形式。充分利用网上地图资源,不但可以提高地理教学的有效性,而且可以促进地理信息技术的学习和应用。 相似文献

在设计人教版的问题研究课“城市的气温为什么比郊区高”这节课时,为了体现地理课堂教学的地方特色,笔者重新设计了“问题研究”的问题,把这节课的课题变成“苏州城为什么越来越热？”。在课堂教学中设计了这样一个活动：先展示了苏州政区图、苏州市区年均气温分布图和苏州市区年降水量分布图,并提出了这样一个问题：“在长江三角洲的苏、锡、常三个城市中,只有苏州一个城市有柑橘树大量分布,其它两个城市都没有,为什么？” 相似文献

In this paper, we discuss the development of electronic atlas in China, with focus on the issues of visualization. We particularly categorise this development into four periods, and then analyse the characters in each period and discuss the visualization issues. The four periods are highlighted: 1) Infant period (<1990) characterized as computer assisted mapping with products of screen maps; 2) Starting period (1991-1995) characterized as object-oriented mapping with products of interactive maps/atlases; 3) Advancing period (1996-2000) characterized as integrated mapping with products of multimedia cartographic maps; 4) New era (> 2001) characterized as web mapping and adaptive map design with products of Internet maps and atlas as well as adaptive maps. It is obvious that the development follows the logical way from static to dynamic, and even real time visualization, from single user to multiple users, from presentation to exploration for effective communication and knowledge construction. Current research and development projects are focused on customisation of atlas information systems for real-time tasks, Internet operability, small displays and mobile environments. The major challenges involved in each of such customisation processes are identified and commented in relation to the further development of visualization. 相似文献

The experiments described in this article combine response time measurements and eye movement data to gain insight into the users' cognitive processes while working with dynamic and interactive maps. Experts and novices participated in a user study with a ‘between user’ design. Twenty screen maps were presented in a random order to each participant, on which he had to execute a visual search. The combined information of the button actions and eye tracker reveals that both user groups showed a similar pattern in the time intervals needed to locate the subsequent names. From this pattern, information about the users' cognitive load could be derived: use of working memory, learning effect and so on. Moreover, the response times also showed that experts were significantly faster in finding the names in the map image. This is further explained by the eye movement metrics: experts had significantly shorter fixations and more fixations per second meaning that they could interpret a larger part of the map in the same amount of time. As a consequence, they could locate objects in the map image more efficiently and thus faster. 相似文献

The growth of the Internet and the digital revolution have meant increased reliance on electronic representations of information. Geospatial information has been readily adapted to the world of cyberspace, and most Web pages incorporate graphics, images, or maps to represent spatial and spatialized data. But flat computer screens do not facilitate a map or graph experience by those who are visually impaired. The traditional method for compensating for nonvisual access to maps and graphics has been to construct hard‐copy tactile maps. In this article, we examine an electronic accommodation for nonvisual users—the haptic map. Using new and off‐the‐shelf hardware—force feedback and vibrotactile mice—we explore how touch can be combined with virtual representations of shapes and patterns to enable nonvisual access to onscreen map or graphic material. 相似文献

Abstract Current geographical information systems (GIS) include functions to create cartographic output interactively or automatically. However, none of the systems presently incorporates mechanisms to ensure correct application of graphic functions. Many of today's users of GIS are not trained in the design and production of graphics and may create maps that confuse or mislead map users. Poorly-designed maps may obliterate the patterns in displayed information. This article investigates ways to improve the quality of GIS graphical displays and increase their effectiveness for decision-making. Alternatives are presented for improving map design in GIS, ranging from non-technical efforts to enhancement of software functionality. Suggestions propose augmenting users' abilities to create maps in an automated environment, using an approach termed amplified intelligence: key decisions default explicitly to users, whose knowledge is amplified by a range of high-level tools to carry out map design operations automatically. 相似文献

Abstract Crucial aspects of the referent phenomena which provide the subject matter for cartographic symbolism are often overlooked by map interpreters in their haste to “read maps at a glance.” The blame rests largely on those practitioners of the environmental sciences who stress the simple, intuitive nature of maps, while effectively ignoring the true complexity of the cartographic communication process. Those persons who are responsible for traditional map interpretation training programs are also at fault for implying, through long emphasis, that symbol identification, position location, and navigation constitute the essence of map analysis. The intuitive acceptability of map symbols in spite of their abstract character is also a deceptive factor. The fact that there is far “more than meets the eye” to map interpretation is easily demonstrated by looking closely at several basic cartographic symbols. In order to become an effective map user the environmental scientist apparently must go well beyond the mastery of conventional map reading principles and learn to deal with diverse informational dimensions in the context of the map use purpose and the physical/cultural make-up of the geographical region under study. 相似文献

In 1977, I published a set of coarse-resolution dot maps that showed the general distributions of soil orders in the 48 states. Through a sequence of copies made by various people, one of those maps eventually appeared in a planning document as a shaded-area map with the title “Principal Peatlands of the United States.” Along the way a saline desert muck of conjectural extent and location was “transformed” into a documented energy resource for the nation. The history of this map offers a clear lesson for mapmakers: we have a three-fold duty, to the data, to the map reader, and to any third party who might be affected by a foreseeable misinterpretation of our maps. 相似文献
