AbstractThe author reflects on some of the main influences on map design which occurred during his own working lifetime in cartography. These include the post-World War II developments in graphic arts technology and the impetus these gave to what is now regarded to 'traditional' cartography; the design challenge of the photomap; theory and research in the nineteen seventies and early nineteen eighties and finally the digital transition.The use of powerful digital systems to experiment with cartographic design, and the improvements in design standards which expert systems may offer to noncartographers are regarded as important prospects in the immediate future. 相似文献

利用数字化的NOAA AVHRR数据进行小比例尺、准同步宏观制图是一种低成本和快速的制图方法。笔者应用本文方法制作了第一幅小比例尺的、完整的中国假彩色卫星影象地图。它包含了全部的南中国海,这是使用其他的遥感数据(如陆地卫星或SPOT卫星)难以做到的。该图采用了热红外、近红外和可见光的红波段所构成的假彩色合成方案,提供了丰富的色彩和影象信息。本图制作时实施的数据处理内容包括:地图投影变换、影象反差增强和锐化、彩色平衡调整、去云处理和海陆分离处理、利用植被指数原理的影象时相修正和数字镶嵌操作等。根据影象地图的载负量和视觉效果,图上精心选取并设计了地理要素、地图符号和注记。该图是应用遥感新技术开发的地图新产品,被十七届国际摄影测量与遥感会议选为展示成果,并被该会评为获奖成果。 相似文献

AbstractMeasurement of areas is necessary in many studies based on maps. Where precise measuring equipment is not available, more simple methods must be used. The information so produced can be improved in value if the degree of accuracy of the measuring technique can be stated. This paper demonstrates a 'model' by which results of the measuring technique can be judged against calculations for the same units, which are exact to one thousandth of a square centimetre. 相似文献

ABSTRACTMaking and sharing maps is easier than ever, and social media platforms make it possible for maps to rapidly attain widespread visibility and engagement. Such maps can be considered examples of viral cartography – maps that reach rapid popularity via social media dissemination. In this research we propose a framework for evaluating the design and social dissemination characteristics of viral maps. We apply this framework in two case studies using maps that reached wide audiences on Twitter. We then analyze collections of maps derived from and inspired by viral maps using image analysis and machine learning to characterize their design elements. Based on our initial work to conceptualize and analyze virality in cartography, we propose a set of new research challenges to better understand viral mapmaking and leverage its social affordances. 相似文献

AbstractThis paper documents ongoing glacier retreat in the eastern part of the Granatspitz Mountains (Hohe Tauern Range, Austrian Alps) for the time period 2003–2009 using aerial photogrammetry. Aerial photographs of 2003, 2006, and 2009 were made available by the Hydrological Service of the Regional Government of Salzburg, the Federal Office of Metrology, Surveying and Mapping, Vienna, and the Regional Government of the Tyrol, respectively. High resolution multi-temporal digital elevation models and digital orthophotos of the area of interest were derived using digital photogrammetric methods to provide a sound basis for glaciological research. Glacier outlines of the three glacial stages were mapped interactively. Temporal change in area and surface height of the glaciers mapped clearly document glacier retreat. Glacier mass balance based on the geodetic method was calculated for Stubacher Sonnblickkees (Glacier). Mean annual specific net balance amounts to ?656 mm w.e. for the time period 2003–2009, with a mass balance gradient of 324 mm w.e. (100 m)?1 and an equilibrium-line altitude of 2995 m a.s.l. Digital orthophoto maps and other thematic maps, e.g. showing surface height change, were prepared to support further data interpretation. Both the study area and its spatio-temporal change were visualized with special emphasis on the glaciers in a computer generated video film. Another film (exposure 29 August 2011) shows the lower part of Stubacher Sonnblickkees and its surroundings for reasons of comparison. 相似文献

AbstractWhilst it can be fairly stated that the post war years have seen an upsurge of interest in the design of maps as printed material, the same cannot be said of the treatment of maps for projection, whether by 35 mm slides or overhead methods. 相似文献

AbstractThis paper describes some results of an attempt to design and to write a general purpose computer program which can be used to produce quality maps of discrete data by the person who has had no training in computer programming. In the first section, the variety of the maps this program can produce is illustrated; in the second section, some of the principles involved in such map production are discussed; in the third section, the input arrangements for using the program are described and, finally, the role of such programs in teaching and research in the years ahead is discussed. 相似文献

AbstractUsing examples from the governmental, commercial and educational sectors, the development of photo maps and mapping using satellite imagery is outlined. The emphasis of this paper is on the design possibilities and limitations which are evident in these products. Contrast and legibility problems and image clutter are considered, but it is concluded that the institutional impediments to the collaboration of specialists in researching and designing such maps may be of most importance in determining progress in the use of such maps. 相似文献

Abstract<title/>During the past 400?years, Taiwan has experienced the dominance of various political regimes, which allowed the development of a diversity of cartographic styles for academic comparison. A detailed analysis of historical maps across centuries demonstrates that this contested island has been illustrated with a blending of reality, misconception and imagination. This paper narrates how maps reveal political rulers’ conscious and unconscious perceptions of this island. We call attention to the abundant cartographic materials in existence and suggest that they can be fascinating materials for the study of the contested colonial histories of this island in various disciplines. 相似文献

AbstractThe development of graphicacy in children has been a laudible and long standing aim of geographical education. The interaction between children and maps in a variety of circumstances is examined and the abilities of children to create their own maps are outlined. The conclusions from such studies can lead to recommendations for map design for children. In particular, the cognitive and graphic processes must be understood and applied. 相似文献

AbstractThis paper describes a methodology for evaluating the planimetric accuracy of three US Civil War maps using GIS and spatial analytical techniques. The case-study is the Battle of Stones River in Tennessee and, in particular, maps depicting the events of December 31, 1862. An examination of the objectives, limitations and techniques employed by the topographer engineers who created the maps provides focus for the quantitative analysis and establishes the historical context needed to understand how and why the maps were constructed. The paper shows how GIS and spatial analysis can be utilized to document vanishing historic landscapes and reconstructing where certain historical events took place. 相似文献
