地图设计与视觉感受的探讨 总被引:7,自引:0,他引:7
视觉地图的信息传递 ,实际上是地图作者的设计思想在地图读者视觉感受中的体现。本文在对人的视觉感受和影响感受效果主要因素分析的基础上 ,提出读者视觉感受的效果是地图信息传递成败和效率高低的关键 ,也是评价地图设计的重要依据的观点 ,进而对地图内容选取和概括指标的确定、地图符号设计、色彩设计、图面配置及整饰设计与视觉感受的关系作了一定的分析 ,并提出了在地图设计中需要注意的一些问题。 相似文献

AbstractThis paper is written primarily with the object of ascertaining how other Colonies and Dominions deal. with the adjustment of their trigonometricallevels; further, since the greater part of Nigeria is now covered by a framework of levels of primary accuracy it is of interest to examine the results. Moreover, the evaluation of the coefficient of refraction, and from it the temperature lapse-rate, is of some importance in view of the recent publication of the War Office Aneroid Tables. These tables are based on a standard lapse-rate of temperature. 相似文献

Two general approaches for compiling maps of components of the water-ice budget in regions of glacier nourishment are compared and the resulting maps are analyzed. The compilation of raw data is based on field measurements rather than remote sensing information.

The chairman of Moscow University's Cartography Department addresses questions about cartography's place in the system of scientific knowledge, qualifications as a science, subject matter, and methods of analysis. Critiques of recent theoretical works both within and outside the USSR lay the groundwork for the author's view of cartography: a multifaceted, interdisciplinary field of knowledge using maps for the presentation and investigation of natural and socioeconomic phenomena. Although few if any strictly cartographic laws exist at present, map use methods are applied widely for the discovery and analysis of laws in other disciplines.

AbstractIn the memoir of the late Capt. G. T. McCaw which appeared in the January number of this Review (vii, 47,2), reference was made to the part which the late Sir David Gill played in the origin of the work on the survey of the Arc of the 30th Meridian in Africa. This year is the centenary of Gill's birth, as he was born in June 1843, and it is therefore timely to give some account of his work during his long term of office as Her Majesty's Astronomer at the Cape which resulted inthe inception and completion of the Geodetic Survey of South Africa and the survey of the Arc to the southern shores of Lake Tanganyika. He died on 24th January 1914. 相似文献

AbstractThe conclusions of this Committee have aroused small interest so far, because war was upon us almost as soon as the publication (1938). They may, however, greatly affect our surveys and maps of the future, and it is time to examine them. First of all, however, it is desirable to see the background against which the Committee's recommendations appear. For that reason the following chronological summary is given. It is divided into three periods, those of Growth, of Hesitation and of War, and it is given to supplement the chronology of the Final Report in matters which are discussed therein. 相似文献

洞庭湖吞吐调蓄数学模型及调洪功能评估 总被引:2,自引:0,他引:2
洞庭湖是一个吞吐调节型湖泊,是我国第二大淡水湖。近年来,洪涝灾害十分频繁,人们的生命财产安全受到严重威胁。为满足洞庭湖减灾防灾综合治理的需要,本文通过对8个不同时相的TM图像计算机解译和面积计算,查明了洞庭湖的面积和容积,建立了湖水面积与水位及湖水体积与水位的相关数学模型,并对其蓄洪调节能力进行评价,获得了满意的效果。该成果对洞庭湖区防洪减灾及综合治理具有十分重要的意义。 相似文献
