The contributions of V. I. Lenin to Soviet cartography, as well as cartographic activity taking place as a direct result of his initiative, are reviewed. He decreed the organization of mapping services and his original and practical recommendations served as a basis for production of significant scientific maps and atlases which were effective tools in the organization and management of the Soviet economy and in educational institutions for many decades.

In the recent history of cartography, atlases deserve a prominent status among cartographic products due to the variety of their thematic content, the rather friendly appearance and their utilization by a wide spectrum of users. Advances in information technology, and more specifically in geographic information systems and digital mapping, have altered the fundamental way of using maps, and thus they have a major impact on every aspect of electronic atlas design and development. Although considerable effort has been made towards the production of electronic atlases, and successful systems are available, there are still a number of factors that must be considered towards the improvement of their design and functional characteristics. This paper elaborates on those factors and suggests a specific approach toward the design and development of electronic atlases, particularly electronic statistical atlases. This approach has been used for the development of the Statistical Atlas of the European Union (STATLAS_EU), which is intended to provide a user-friendly resource for statistical analysis.  相似文献

Principles and objectives governing Soviet thematic mapping of nearby planets are outlined, types of information sources for such mapping categorized, and the suitability of different types of information sources for thematic mapping are evaluated. This is followed by a classification of thematic planetary maps according to type. The need for a standardized, systems approach to the determination of map scales, compilation and generalization, symbolization, and map design is emphasized as an essential prerequisite for the development of complex atlases of individual planets, atlases of “comparative planetology,” and the establishment of “planetary information systems.” Translated by Jay Mitchell; PlanEcon, Inc.; Washington, DC 20005 from: Vestnik Moskovskogo Universiteta, geografiya, 1987, No. 6, pp. 60-67.  相似文献

Measures to improve the effectiveness and informational content of general reference maps and other materials in atlases designed for the general public are outlined. Emphasis is placed upon (a) enhancing the readability and visual appeal of color “landscape” maps, providing a generalized, small-scale aerial view of the region(s) of interest–this through the application of principles of perception and colorimetry–and (b) developing larger-scale “reference” maps maximizing levels of graphic detail without jeopardizing ease of perception–this based on a careful study of general reference maps in atlases worldwide and broadly based testing of users with various levels of map reading skills.

Abstract

Since the early 1980s, we have seen a new influx of numerous geopolitical atlases. They have been produced to meet society's implicit need to fix the boundaries of international issues and the relationships of force between the various powers. These atlases clearly express established ideologies and allow us to determine various trends of thought; messages which the authors wish us to take on board by studying cartographic themes. This is the approach we will be taking in this article.

In this paper, we aim to show the epistemological development of geopolitical atlases. The first part of the article gives the general outline of the epistemological development of geopolitical atlases, in which two main periods stand out. The first corresponds with the 1980s, which can be described as a realist decade. The state was a geopolitical player that could not be overlooked within a bipolar world; maps showing conflicts between the two major powers and thematic maps showing an ideological clash between them are typical of the period. The second period, corresponding with the 1990s, begins with the fall of the regimes in the Soviet bloc. This period can be described as having a neo-realist approach, where the threat from the East had moved to terrorism and drug trafficking. The atlases follow the geopolitical development of the world and describe international structural changes. In conclusion, the paper will return to the important educational and informative role of atlases and their effects on the ideas they are able to disseminate amongst the population.  相似文献

Abstract

This paper explores the potential of a different kind of counter-mapping. It focuses upon a critical reading of five different architectural atlases and argues that their construction and design reveals how ‘re-cartographies’ can narrate novel stories about places. The narrative power of these atlases is traced back to a focus upon relations between phenomena, and a careful consideration of how to map the mutability and dynamism of the built and natural environment. They offer new kinds of selection, classification and symbolisation; deploy hybrid forms to destabilize taken for granted binary distinctions between nature and culture; use montage and juxtaposition to reveal scalar linkages; re-imagine figure–ground relationships to reveal functional city forms and processes; and explore the potential of meta-structures in the relations between different maps in an atlas layout. Taken together, they show how the cartographic imagination can escape from standard and accepted orthodoxies. They also reveal the importance of a situated and historicized narrative approach to all mapping, and offer a kind of counter-mapping from an academic field, which might allow more creative professional engagement with the making of places.  相似文献

Abstract

</p>Gamepads and joysticks have the potential to improve spatial navigation in virtual globes, block diagrams and 2D maps. Digital school atlases, in particular, can become more engaging if support for gamepads and joysticks is added, as children and adolescents are very proficient at using these devices. The fusion of gaming devices and interactive school atlases offers interesting new use cases: teachers can control a digital wall map with a remote-control gamepad while lecturing from the front of the classroom, or students can explore maps on their personal computers using an enticing way to interact. This paper presents these use cases, the characteristics of the most common gaming devices, and discusses spatial navigation with gamepads and joysticks for globes, block diagrams and 2D maps. The ideas presented originated from the ongoing development of a new, interactive version of the Swiss World Atlas for schools.  <a href="relate_search.aspx?pcid=E62459D214FD64A3C8082E4ED1ABABED5711027BBBDDD35B&cid=A41A70F4AB56AB1B&aid=5A172168B32099AE544AB8BD3EC6ADF4&language=1" target="_blank">相似文献</a>    </div> <div><br></div> <div class="clear"></div> </div> <div class="clear"></div> </div> <div class="search_article"> <div class="search_articleleft">10.</div> <div class="search_articleright"> <div> <a class="a1" href="view_abstract.aspx?pcid=E62459D214FD64A3C8082E4ED1ABABED5711027BBBDDD35B&cid=A41A70F4AB56AB1B&jid=85A5E524813453D9DA77A860E3F8F7A3&aid=5E22F304672582CA9D1E9A3BB897B031&yid=9475FABC7A03F4AB&vid=D997634CFE9B6321&iid=CA4FD0336C81A37A&sid=CA4FD0336C81A37A&eid=5D311CA918CA9A03&referenced_num=" target="_blank">地图集:重构复杂非线性地理世界的“百科全书”</a>   <em><strong></strong></em>   </div> <div> <a href="search_by_author.aspx?subject=astronomy_earth_science&major=chx&field=author_name&encoding=utf-8&q=%e7%8e%8b%e5%ae%b6%e8%80%80" target="_blank">王家耀</a> <a class="a2" href="#">《测绘地理信息》</a>2021,46(1):1-8 </div> <div>地图学是一门经过数千年的演进发展形成的科学,地图(地图集)是地图科学研究的主阵地,是任何时代和社会都不可或缺的,对人们的工作、学习和生活具有重要作用和意义。首先,简要论述了地图学作为一门科学的社会实践和科学实践的演进发展规律,以及地图集的特点;然后,从哲学角度分析与论述了地图是怎样重构复杂非线性地理世界的(实现由"地理世界"到"地图世界"的转变),人们是怎样利用地图进一步认识复杂非线性地理世界的(实现由"地图世界"到"地理世界"的转变),提出了基于传感器网络的由"感知的地理世界"到"重构的地理世界"再到"认知的地理世界"、指导行动并反馈信息的"双向"转变的认知模式;最后,论述了地图集作为重构复杂非线性地理世界的"百科全书"的作用,举例说明了中国改革开放以来地图集的快速发展和水平的大幅提升,并阐明人工智能时代中国地图集成果将比以往任何时候都更加兴旺发达,地图集作为人们进一步认知复杂非线性地理世界的"百科全书"的功能作用将比以往任何时候都更加强大。  <a href="relate_search.aspx?pcid=E62459D214FD64A3C8082E4ED1ABABED5711027BBBDDD35B&cid=A41A70F4AB56AB1B&aid=5E22F304672582CA9D1E9A3BB897B031&language=2" target="_blank">相似文献</a>    </div> <div><br></div> <div class="clear"></div> </div> <div class="clear"></div> </div> <div class="search_article"> <div class="search_articleleft">11.</div> <div class="search_articleright"> <div> <a class="a1" href="view_abstract.aspx?pcid=E62459D214FD64A3C8082E4ED1ABABED5711027BBBDDD35B&cid=A41A70F4AB56AB1B&jid=1EAFE3E626147FFD99DAD0378F9E1890&aid=26AAC6900D0B8A114D0E009CBF4F4E03&yid=FF7AA908D58E97FA&vid=771152D1ADC1C0EB&iid=E158A972A605785F&sid=28F9D9CF04F424FF&eid=89AC6B0ADBEA2741&referenced_num=" target="_blank">Design and Implementation of a Model,Web-based,GIS-Enabled Cancer Atlas</a>   <em><strong></strong></em>   </div> <div> <a class="a2" href="#">《The Cartographic journal》</a>2013,50(4):246-260 </div> <div><b>Abstract</b></p>The design and development of a highly interactive web-based, GIS-enabled atlas is reported. The atlas is a prototype, designed as a model for implementation of atlases to support government cancer-control activities. This model integrates symbolisation and design principles from print cartography, interaction strategies from exploratory geovisualisation, and web-map/web-feature service advances from GIS. The atlas has been implemented using a client-server architecture. It makes use of two open-source GIS tools, PostGIS (as the system database) and GeoServer (to connect the database to the client mapping application). The client mapping application has been built in Macromedia Flash. The entire client-server architecture is described, then direct primary emphasis is focused on the client mapping application. For this component of the system, the interface design strategy is detailed, the approach taken to implement this strategy in Flash is documented, and the mechanisms developed to build dynamic links from the client to the underlying database through the server are outlined. Features of the atlas are presented through a prototypical use scenario for a target user.  <a href="relate_search.aspx?pcid=E62459D214FD64A3C8082E4ED1ABABED5711027BBBDDD35B&cid=A41A70F4AB56AB1B&aid=26AAC6900D0B8A114D0E009CBF4F4E03&language=1" target="_blank">相似文献</a>    </div> <div><br></div> <div class="clear"></div> </div> <div class="clear"></div> </div> <div class="search_article"> <div class="search_articleleft">12.</div> <div class="search_articleright"> <div> <a class="a1" href="view_abstract.aspx?pcid=E62459D214FD64A3C8082E4ED1ABABED5711027BBBDDD35B&cid=A41A70F4AB56AB1B&jid=F5E15F49EFA6F3FA04B5BDFFC68ED5CC&aid=4086B3DF697F6675BC2A69365FD34EA1&yid=FF7AA908D58E97FA&vid=1371F55DA51B6E64&iid=0B39A22176CE99FB&sid=EB552E4CFC85690B&eid=4C100B7696CE9E24&referenced_num=" target="_blank">Atlas Mapping in the 21st Century</a>   <em><strong></strong></em>   </div> <div> <a class="a2" href="#">《制图学和地理信息科学》</a>2013,40(2):149-158 </div> <div>Atlases are changing. The paper paradigm of maps and atlases has pervaded recent cartographic history. By nature that paradigm serves, as well as defines, a specific audience in terms of use and presentation. In the lab and at the printing press, the paper paradigm demands certain design and production flows that will drastically change through evolutions in data structures, mapmaking techniques, and presentation methods. Technological transformations in mapping influence much of this change. The implications for the creation and distribution of atlases are significant. With that in mind, this paper addresses a number of issues that relate to the technological evolution of atlases from paper to digital products: the distinction between paper and digital products and services and the implications of that distinction for atlas design—particularly for web-based services; facilitating data and its application to the evolution of map/atlas products; and a redefinition of "atlas" and the "audience" for an atlas.  <a href="relate_search.aspx?pcid=E62459D214FD64A3C8082E4ED1ABABED5711027BBBDDD35B&cid=A41A70F4AB56AB1B&aid=4086B3DF697F6675BC2A69365FD34EA1&language=1" target="_blank">相似文献</a>    </div> <div><br></div> <div class="clear"></div> </div> <div class="clear"></div> </div> <div class="search_article"> <div class="search_articleleft">13.</div> <div class="search_articleright"> <div> <a class="a1" href="view_abstract.aspx?pcid=E62459D214FD64A3C8082E4ED1ABABED5711027BBBDDD35B&cid=A41A70F4AB56AB1B&jid=1EAFE3E626147FFD99DAD0378F9E1890&aid=26AAC6900D0B8A1106485F3FCD7450E1&yid=FF7AA908D58E97FA&vid=771152D1ADC1C0EB&iid=E158A972A605785F&sid=D0182A31A5EB14BA&eid=358F98408588E522&referenced_num=" target="_blank">Observations Italian Composite Atlases and a Belgian Undescribed Copy</a>   <em><strong></strong></em>   </div> <div> <a class="a2" href="#">《The Cartographic journal》</a>2013,50(4):296-303 </div> <div><b>Abstract</b></p>Although Italian composite atlases of the 16th century are seldom mentioned in the literature on historical cartography, these collections are very important for preserving a large number of maps that might otherwise be lost forever.

Although the origins of cybercartography were largely conceptual in nature, the evolution of cybercartography to date has been an iterative process reflecting the creative interplay between theory and practice. A major step forward was made in 2002 when the Geomatics and Cartographic Research Centre at Carleton University received a $2.5 million grant from the Social Sciences and Humanities Research Council of Canada to explore the utility of cybercartography to what was described as the New Economy. By 2006, the interaction between theory and practice had led to considerable advances in cybercartography as a holistic, location-based concept and two new cybercartographic products, the Cybercartographic Atlas of Antarctica and the Cybercartographic Atlas of Canada's Trade with the World, were produced. Between 2006 and 2009, cybercartography was further developed as a result of interaction with indigenous communities, especially in Canada's north and new interactive atlases such as the Kitikmeot Place Names Atlas and the Community Atlas of Arctic Bay were created in cooperation with the communities involved. The Nunaliit Cybercartographic Atlas Framework, built using open source software and open specifications and standards, was developed to facilitate direct input to these atlases. Cybercartography is now entering a new phase in both theory and practice building on a recently completed prototype atlas of Indigenous Perspectives and Knowledge.  <a href="relate_search.aspx?pcid=E62459D214FD64A3C8082E4ED1ABABED5711027BBBDDD35B&cid=A41A70F4AB56AB1B&aid=58A97B94B44A0BF9B6826E60571A875B&language=1" target="_blank">相似文献</a>    </div> <div><br></div> <div class="clear"></div> </div> <div class="clear"></div> </div> <div class="search_article"> <div class="search_articleleft">15.</div> <div class="search_articleright"> <div> <a class="a1" href="view_abstract.aspx?pcid=E62459D214FD64A3C8082E4ED1ABABED5711027BBBDDD35B&cid=A41A70F4AB56AB1B&jid=1EAFE3E626147FFD99DAD0378F9E1890&aid=27B80CC9DD71BE1B3167E7DF287C4E25&yid=FF7AA908D58E97FA&vid=771152D1ADC1C0EB&iid=0B39A22176CE99FB&sid=A04140E723CB732E&eid=D3E34374A0D77D7F&referenced_num=" target="_blank">The Representation of Disputed Political Boundaries in General Atlases</a>   <em><strong></strong></em>   </div> <div> <a class="a2" href="#">《The Cartographic journal》</a>2013,50(2):20-28 </div> <div><b>Abstract</b></p>The extremely complex problems of boundary representation in general atlases are critically examined by a Lecturer in Geography at University College, London.

The semantic web is an extension of the fundamental ideas of the World Wide Web, building a web of data through annotation of metadata and data with hyperlinked resources. Within the framework of the NETMAR project, an interconnected semantic web resource was developed to aid in data and web service discovery and to validate Open Geospatial Consortium Web Processing Service orchestration. A second semantic resource was developed to support interoperability of coastal web atlases across jurisdictional boundaries. This paper outlines the approach taken to producing the resource registry used within the NETMAR project and demonstrates the use of these semantic resources to support user interactions with systems. Such interconnected semantic resources allow the increased ability to share and disseminate data through the facilitation of interoperability between data providers. The formal representation of geospatial knowledge to advance geospatial interoperability is a growing research area. Tools and methods such as those outlined in this paper have the potential to support these efforts.  <a href="relate_search.aspx?pcid=E62459D214FD64A3C8082E4ED1ABABED5711027BBBDDD35B&cid=A41A70F4AB56AB1B&aid=58A97B94B44A0BF9D1BBF1F6DC7AA82B&language=0" target="_blank">相似文献</a>    </div> <div><br></div> <div class="clear"></div> </div> <div class="clear"></div> </div> <div class="search_article"> <div class="search_articleleft">18.</div> <div class="search_articleright"> <div> <a class="a1" href="view_abstract.aspx?pcid=E62459D214FD64A3C8082E4ED1ABABED5711027BBBDDD35B&cid=A41A70F4AB56AB1B&jid=0B356E83365D5D5B3C2287BA632FFDD4&aid=9A1A512AA075688C5815270EA3890F39&yid=67289AFF6305E306&vid=59906B3B2830C2C5&iid=CA4FD0336C81A37A&sid=769BD58726D66E7D&eid=1B97AE5098AEB49C&referenced_num=总被引:1,自引:0,他引:1" target="_blank">Defining a Digital Earth System</a>   <em><strong>总被引:1,自引:0,他引:1</strong></em>   </div> <div> <a href="search_by_author.aspx?subject=astronomy_earth_science&major=chx&field=author_name&encoding=utf-8&q=Karl+E.+Grossner" target="_blank">Karl E.

Clarke</a> <a class="a2" href="#">《Transactions in GIS》</a>2008,12(1):145-160 </div> <div>In a 1998 speech before the California Science Center in Los Angeles, then US Vice‐President Al Gore called for a global undertaking to build a multi‐faceted computing system for education and research, which he termed “Digital Earth.” The vision was that of a system providing access to what is known about the planet and its inhabitants’ activities – currently and for any time in history – via responses to queries and exploratory tools. Furthermore, it would accommodate modeling extensions for predicting future conditions. Organized efforts towards realizing that vision have diminished significantly since 2001, but progress on key requisites has been made. As the 10 year anniversary of that influential speech approaches, we re‐examine it from the perspective of a systematic software design process and find the envisioned system to be in many respects inclusive of concepts of distributed geolibraries and digital atlases. A preliminary definition for a particular <i>digital earth system</i> as: “a comprehensive, distributed geographic information and knowledge organization system,” is offered and discussed. We suggest that resumption of earlier design and focused research efforts can and should be undertaken, and may prove a worthwhile “Grand Challenge” for the GIScience community.  <a href="relate_search.aspx?pcid=E62459D214FD64A3C8082E4ED1ABABED5711027BBBDDD35B&cid=A41A70F4AB56AB1B&aid=9A1A512AA075688C5815270EA3890F39&language=1" target="_blank">相似文献</a>    </div> <div><br></div> <div class="clear"></div> </div> <div class="clear"></div> </div> <div class="search_article"> <div class="search_articleleft">19.</div> <div class="search_articleright"> <div> <a class="a1" href="view_abstract.aspx?pcid=E62459D214FD64A3C8082E4ED1ABABED5711027BBBDDD35B&cid=A41A70F4AB56AB1B&jid=1EAFE3E626147FFD99DAD0378F9E1890&aid=94B60B1814EE12C5537E50EF62518E7F&yid=FF7AA908D58E97FA&vid=771152D1ADC1C0EB&iid=CA4FD0336C81A37A&sid=1371F55DA51B6E64&eid=ECE8E54D6034F642&referenced_num=" target="_blank">Geographic information systems in Europe</a>   <em><strong></strong></em>   </div> <div> <a class="a2" href="#">《The Cartographic journal》</a>2013,50(1):40-42 </div> <div><b>Abstract</b></p>Electronic atlases possess certain advantages over their paper counterparts. However these are not achieved lightly because of the considerable differences between these media, particularly in terms of cartographic design. These problems, and the process of converting an existing atlas of marine information into an electronic version, are the subject of this paper.  <a href="relate_search.aspx?pcid=E62459D214FD64A3C8082E4ED1ABABED5711027BBBDDD35B&cid=A41A70F4AB56AB1B&aid=94B60B1814EE12C5537E50EF62518E7F&language=1" target="_blank">相似文献</a>    </div> <div><br></div> <div class="clear"></div> </div> <div class="clear"></div> </div> <div class="search_article"> <div class="search_articleleft">20.</div> <div class="search_articleright"> <div> <a class="a1" href="view_abstract.aspx?pcid=E62459D214FD64A3C8082E4ED1ABABED5711027BBBDDD35B&cid=A41A70F4AB56AB1B&jid=0B356E83365D5D5B3C2287BA632FFDD4&aid=94D7BABB0E26FC29F5258F138BAB3BEA&yid=FF7AA908D58E97FA&vid=BCA2697F357F2001&iid=94C357A881DFC066&sid=50FF665B2730AEEC&eid=141C24EC1980F602&referenced_num=" target="_blank">Location Based Social Networks – Definition,Current State of the Art and Research Agenda</a>   <em><strong></strong></em>   </div> <div> <a href="search_by_author.aspx?subject=astronomy_earth_science&major=chx&field=author_name&encoding=utf-8&q=Oliver+Roick" target="_blank">Oliver Roick</a>  <a href="search_by_author.aspx?subject=astronomy_earth_science&major=chx&field=author_name&encoding=utf-8&q=Susanne+Heuser" target="_blank">Susanne Heuser</a> <a class="a2" href="#">《Transactions in GIS》</a>2013,17(5):763-784 </div> <div>The growing penetration of GPS equipped smartphones allowing users to constantly share geographic information on their current whereabouts has led the way to an augmentation of existing <i>Social Network Sites</i> with location‐based features or the creation of new ones exclusively around geographic information. Within these <i>Location Based Social Networks</i> vast amounts of geographic information are allocated, which attracted the attention of researchers with various scientific backgrounds. This article presents a comprehensive definition of this special type of <i>Social Network Site</i> and an overview of research activities, which are currently conducted using the data. Finally, a research agenda for GIScience is drawn from existing research directions.  <a href="relate_search.aspx?pcid=E62459D214FD64A3C8082E4ED1ABABED5711027BBBDDD35B&cid=A41A70F4AB56AB1B&aid=94D7BABB0E26FC29F5258F138BAB3BEA&language=1" target="_blank">相似文献</a>    </div> <div><br></div> <div class="clear"></div> </div> <div class="clear"></div> </div> </div> </div> </div> </div> </td> </tr> </table> </td> </tr> </table> <table width="870" border="0" align="center" cellpadding="0" cellspacing="0"> <tr> <td height="40" align="center" class="fo2"> <a href="#" onClick="this.style.behavior='url(#default#homepage)';this.setHomePage('http://td.alljournals.com.cn')">设为首页</a> <span class="STYLE1">|</span> <a href="http://www.alljournals.cn/note.aspx">免责声明</a> <span class="STYLE1">|</span> <a href="http://www.e-tiller.com"><u>关于勤云</u></a> <span class="STYLE1">|</span> <a href="javascript:window.external.addFavorite('http://td.alljournals.com.cn','期刊界 All Journals---天文学、地球科学')">加入收藏</a></td> </tr> <tr> <td align="center" class="fo3"> <p align="center"> Copyright<span lang="en">©<a href="http://www.e-tiller.com"><u>北京勤云科技发展有限公司</u></a>  京ICP备09084417号    </span></p> </td> </tr> </table> </div> </body> </html>
