Google Hacking技术分析及防范对策研究

解释了Google hacking的定义,着重介绍了当前流行的Google hacking技术,最后阐述了防范Google hacking的几种措施.     

Google Earth的主要功能及其在广电行业的应用

本文简要介绍Google Earth的基本使用方法,具体说明其在广电行业的应用。     

用Google Earth辅助有线电视网络规划设计

利用Google Earth全球卫星地图集成软件，截取清晰的卫星照片在设计工具软件上进行有线电视规划设计；或者在Google Earth上用地标表示有线电视的前端和光节点现状，用画线工具描绘光缆、电缆和管道资源，叠加新建的发展区和道路街道的图纸，为辅助有线电视网络规划设计起到事半功倍的作用。     

User requirements for geo-collaborative work with spatio-temporal data in a web-based virtual globe environment

Web-based tools developed in the last couple of years offer unique opportunities to effectively support scientists in their effort to collaborate. Communication among environmental researchers often involves not only work with geographical (spatial), but also with temporal data and information. Literature still provides limited documentation when it comes to user requirements for effective geo-collaborative work with spatio-temporal data. To start filling this gap, our study adopted a User-Centered Design approach and first explored the user requirements of environmental researchers working on distributed research projects for collaborative dissemination, exchange and work with spatio-temporal data. Our results show that system design will be mainly influenced by the nature and type of data users work with. From the end-users' perspective, optimal conversion of huge files of spatio-temporal data for further dissemination, accuracy of conversion, organization of content and security have a key role for effective geo-collaboration.     

Google Web安全检测工具研究

Skipfish是Google 2010年推出的一款开源Web安全检测工具,与Nikto和Nessus等工具相比,skipfish使用递归抓取和基于字典的探针技术生成交互式目标网站地图,在性能上采用单线程复用技术、自定义的http堆栈和启发式行为分析等技术减少了网络探测流量,使其具有显著的速度优势.文章针对其源码,重点分析了其使用主要的数据结构、执行流程、多I/O异步机制和字典的使用,对于理解Skipfish软件架构和关键技术并以此为基础进行应用扩展和优化提供了有力的帮助.

Remote Sensing Monitoring and Comparison of Urban Land Cover Changes in Typical Cities in China-Kazakhstan Arid Region based on Cloud Platform

Urban land cover composition is the key factor affecting the living environment and urban ecosystem service. Based on the Google Earth Engine platform, Landsat 5/8 remote sensing image data were used to adopt the improved "Vegetation-Impervious Surface-Soil" model and linear spectral mixed decomposition method. The variation characteristics of land cover in Nur-Sudan, Almaty, Urumqi cities from 1990 to 2015 were compared and analyzed. The results show that the urban built-up area of Urumqi city expanded the largest area of the three cities from1990 to 2015, with an expansion of 349.81 km², followed by Nur-Sultan, with a city expansion area of 158.16 km². As the capital of Kazakhstan was relocated from Almaty to Nur-Sultan, the city of Almaty expanded the slowest during the entire period, with a total expansion of 126.23 km². In the urban built-up area, the urban surface in Urumqi increased by 7.10% from 1990 to 2015, and the Nur-Sultan and Almaty decreased by 14.9% and 4.49%，respectively. The green space component of the built-up area, Nur-Sultan increased by 6.68% from 1990 to 2015, while Urumqi and Almaty decreased by 6.65% and 2.75%，respectively. The different surface cover patterns of cities are different for different reasons. Urumqi is mainly supported by national policies, and Almaty is known for its historical background and urban planning, while the rapid development of Nur-Sudan was affected by the relocation of Kazakhstan.     

一种基于Google Maps的土地利用信息发布平台

目前常见的Web地图服务仅支持浏览和查询,不支持矢量数据的发布.文章提出一种基于Google Maps的WebGIS构建方法,支持多种浏览器的矢量数据互操作及空间分析.针对郑州市土地利用信息发布需求,采用B/S架构,借助Google Maps API和AJAX技术,实现了土地利用信息系统化,标准化发布平台.该平台响应速度快,面向多种用户,支持数据共享,能更好的为土地利用变化研究及土地整理决策提供服务.     

无人运输机地面控制站显示界面的仿真系统

为实现地面控制站操作员对民用无人机的安全控制,提出了地面控制站集飞行仪表、地图综合界面显示设计方案. 采用GL Studio 和VC++ 6.0混合编程的方式,实现对飞行仪表显示界面的设计;使用VC++6.0 对Google Earth二次开发实现地面控制站地图显示功能. 将微软模拟飞行X作为飞行仪表和地图界面的数据驱动,通过UDP传输协议,实现仿真系统的综合测试. 测试结果表明,该系统设计可以为地面控制站操作员提供完整的态势信息,提高操作员的决策效率,为研究地面控制站显示界面工效问题提供新的方法.     

基于Google Maps API的旅游特色数据库的设计与实现

Google Maps API[1]所具有的开放式、低成本和易用性等特点,使其能够应用到气象、地理,以及旅游等各个领域。旅游特色数据库是基于Web实现的一种新型GIS旅游服务,本文正是以建立旅游特色数据库为例,探讨了GoogleMaps API在旅游方面的应用。
