海图出版数据更新技术研究

本文在分析了海图更新源数据和我国海图出版数据特点的基础上,深入研究了利用海图更新源数据实现海图出版数据在服务器端交互式更新和在客户端自动更新的关键技术,并具体探讨了在MicroStation V8系统平台下,通过二次开发的途径实现海图出版数据更新的思路与方法。     

多源地图数据出版的探讨

当前多源地图数据的非共享性等特点严重制约了地图数字出版流程的顺利开展。为了有效解决多源地图数据到印前数据的转换问题,根据多源地图数据的类型及特点,结合出版对地图数据的特殊要求,建立并实现了一套完整的由多源地图数据转换为印前数据的方案,并通过具体应用得到有效的验证。     

海图出版质量检测系统的设计与实现

从目前海图出版的实际出发,分析了数字环境下海图生产质量控制需要解决的具体问题,以用户为最终目标设计,阐述了海图出版质量检测系统的总体结构和实现的技术思路。     

International Journal of Sediment Research(IJSR)-Order Form(2015)(ISSN 1001-6279)

正Editing Board address:IRTCES,20 West Chegongzhuang Rd.,Beijing 100048,ChinaIJSR is the journal of THE WORLD ASSOCIATION FOR SEDIMENTATION AND EROSION RESEARCH(WASER)and is edited by the International Research and Training Center on Erosion and Sedimentation(IRTCES).     

AIMS AND SCOPE

正This journal is established by the Institute of Engineering Mechanics(IEM),China Earthquake Administration,to promote scientific exchange between Chinese and foreign scientists and engineers so as to improve the theory and practice of earthquake hazards mitigation,preparedness,and recovery.To accomplish this purpose,the journal aims to attract a balanced number of papers between Chinese and international authors by publishing original papers and invited papers addressing state-of-the-art knowledge and     

在线地图集发布与服务系统的设计与实现

地图集作为反映一个地区或一种领域研究成果的地图集合,是测绘行业的一个重要组成部分,传统地图集编制与发布的成果多为纸质版,制作与发布周期比较长,更新速度慢。该系统对在线地图集发布与服务系统进行开发,有效地缩短了地图集编制时间,提高了地图集编制与发布的效率。在对整个系统进行了完整的设计后,对相关关键技术进行了研究,最后实现了整个系统的开发,并对系统主要功能做出展示。     

测绘期刊面临的问题与对策研究

当然随着社会生活的节奏继续加快,需求的多样性,市场竞争的加剧,国际合作的紧迫性,网络3G技术的普及,以及传统期刊管理的意识理念的不足,这些都给我国期刊事业的发展带来了新的挑战。测绘类的期刊也同样面临以上来自市场、技术、理念层面的诸多挑战。期刊永远是时代的记录者和践行者,改革已经毫无争议地成为期刊业高速发展的根本动力。测绘期刊业市场还有很多尚未开拓的领域,亟待去识别、去利用,调整策略,实现测绘期刊品牌化,国际化,服务个性化,盈利多样化,制度透明化,这些都是当前测绘期刊发展的机会。     

一种面向网络发布的海洋数据库引擎

To meet the requirements of efficient management and web publishing for marine remote sensing data, a spatial database engine, named MRSSDE, is designed independently. The logical model, physical model, and optimization method of MRSSDE are discussed in detail. Compared to the ArcSDE, which is the leading product of Spatial Database Engine, the MRSSDE proved to be more effective.     

基于ArcGIS Server的GIS Web服务自动发布关键技术研究

Web GIS技术主要采用GIS Web服务方式对外提供资源访问和空间分析能力。GIS Web服务提高系统资源利用率,扩大信息使用范围,但GIS Web服务主要依赖于服务器端GIS平台提供的可视化工具进行后台发布,前台用户无法根据自己业务需要自动发布GIS Web服务。文中基于ArcGIS Server平台研究一种GIS Web服务自动发布方案,以双丰林业局林政资源服务系统的在线采编模块为例,阐述该案例的应用。     

Support for,and Impacts of Publishing in the Annals of the AAG: The Authors and and Editor Speak

A survey of 176 authors who published in the Annals between 1988 and 1993 provides insights into why authors submitted their research to the journal, what support they received, and the impacts of the publication on their careers. Most decided themselves to submit their work, and one-third received support from research grants; cartographic assistance and graduate assistants were less important. The major benefits of publishing in the Annals were visibility in one's department, contact with other geographers, and requests for reprints. Most authors presented their ideas at professional meetings prior to submission. Promotion and salary Inc.reases were benefits for women, assistant professors, associate professors, and physical geographers. Authors considered their articles as original examinations that yielded new results, contributed to theory, stimulated debate, and helped bridge gaps inside and outside of geography. These results are useful in helping individual authors and for administrators in identifying the kinds of research support needed by authors publishing in the Annals.
