《江苏省领导工作用图》的设计思想

本文阐述了《江苏省领导工作用图》2013年第一版的生产情况和设计思想。对《江苏省领导工作用图》编制工作进行经验总结和设计思想的剖析,有利于该地图作品的更新完善,有利于提高测绘部门为政府服务的综合实力,也可为编制同类地图作品提供参考。     

自下而上基于标准图幅的滩涂面积量算研究

滩涂面积量算是滩涂资源调查中的一项重要工作内容,其结果数据是调查成果的总体表现与直观反映,为滩涂围垦规划调整、围垦工程合理建设提供了数据支持。通过对标准图幅内的滩涂分布类型进行归纳整理,提出了一种自下而上基于标准图幅的滩涂面积量算方法：首先利用标准图幅内的等深线、岸线实现滩涂面的快速生成,其次计算滩涂面包含的水深点平均高程值判断滩涂类型,最后根据不同条件对滩涂面积分类量算统计。在2011年浙江省滩涂资源调查中的实践证明,该方法简单易用,具有一定应用价值。     

浅析《重庆历史地图集·第一卷 古地图》对古地图的修复

主要通过对古地图在保存质量、历史属性和数字化过程三方面的特性进行阐述,论述了修复古地图的必要性,提出了"修旧如旧"的基本修复原则,并简要介绍了《重庆历史地图集·第一卷古地图》中对古地图的修复流程,描述了变形矫正、颜色调整、脏面去除、折痕消除和图面补缺等五个具体的操作方法,总结了在古地图修复过程中需要考虑的问题。     

两江新区东部区域地形图投影变形处理方法

两江新区东部区域位于重庆市独立坐标中东带结合部,无论采用重庆市独立坐标系中带还是东带,每千米边长高斯投影长度变形都在1．0～4．0 cm之间,超出规范规定。本文研究并确定控制两江新区投影变形的最终方案,建立了两江新区工程坐标系与重庆市独立坐标系的坐标转换关系,提出并编程实现了DXF格式地形图的坐标转换方法。     

地图的多样化实现

女性一直被认为缺少空间感和方向感,但在借助地图指向时,这种现象就不那么明显了.随着女性活动范围的扩大,地图的作用就越发显得重要.文章分析了现行地图不为女性常用的原因,提出女性参与设计编辑面向女性的专用地图,使地图表现更加多样化,同时,借助因特网、智能手机等数字信息引导,使得女性使用地图更加便捷、有效.     

Deconstructing Galbraith: A Geostatistical Analysis of Cartographic Intent

Abstract

This study uses cartometric techniques to reveal cartographic design considerations operative in Frank H. Galbraith’s 1897 railway mail service training maps. Galbraith’s maps make extensive use of humorous cartouches intended to serve as mnemonic devices for learning railway mail service routes. Poisson and quadrat point pattern analyses are performed on all eight maps in the series to determine whether the mimetic symbols are clustered along the railway mail routes or dispersed throughout the mapped spaces to achieve better graphic balance. Evidence overwhelmingly indicates that the placement of the mnemonic symbols was primarily driven by design considerations. The study therefore proves that it is possible to use cartometric techniques to deconstruct the map document to determine the cartographic design principles operative during the map's construction.     

地图集认知功能设计实践——以《中国市售水果蔬菜农药残留水平地图集》为例

地图可视化设计常包含地图认知功能设计、信息传输功效设计、地图视觉效果设计。其中地图认知功能设计是地图集的设计中最基本且最重要的环节。在此环节中,原始数据经过数据形态分析、数据处理与转化、制图模型的建立等过程,形成制图数据以及地图集的内容体系结构。本文以《中国市售水果蔬菜农药残留水平地图集》的设计为例,展示了地图集的地图认知功能设计过程。这个过程体现了地图信息论、地图模型论和地图空间认知论的思想,蕴含了地图的思想美、科学美、技术美和功能美。     

The Use of Maps in Turkish Newspapers

This study analyzes the use of maps in Turkish newspapers in order to evaluate their potential to contribute to the enhancement of geographic knowledge in society. This study reviewed the content of three Turkish newspapers published between January 2008 and August 2012. Only 835 maps were used in the newspapers during the study period, or an average of 278 maps per newspaper. During the study period, about 15,720 news articles were published per month in the three newspapers; however, only five of these were illustrated with a map. The study reveals the potential for Turkish newspapers to increase society's geographic awareness with additional published maps.     

Determining safe yield and mapping water level zoning in groundwater resources of the Neishabour Plain

Groundwater is a crucial sources of water supply, especially in arid and semi-arid areas around the world. With uncontrolled withdrawals and limited availability of these resources, it is essential to determine the safe yield of these valuable resources. The Hill method approach was used in this study to determine the safe yield the Neishabour aquifer in Khorasan Razvi province in Iran. The results showed that the safe yield in the Neishabour aquifer is 60% lower than the current pumping amounts...
