随着我国城市化进程的快速发展,房产信息越来越受到公众的关注,传统的房管系统由于地图保密因素,向公众提供的房产信息常以文字结合照片的方式进行描述,缺乏空间位置,展示的效果较差.本文主要介绍了基于天地图提供的地理信息服务框架,充分利用天地图应用程序接口(API),将房产信息与在线的地图服务结合,实现了房屋小区、新房二手房、房屋租赁的空间定位和信息查询统计等功能,向公众提供专业的、有特色的基于空间位置的房产地理信息服务. 相似文献

Web Mapping APIs (WMAs), such as Google Maps API, are widely used by researchers across different fields to develop geospatial Web applications. Among maps and map functionalities provided through WMAs, route and direction are prominent and commonly available. Given that each WMA uses a different map database and a different set of assumptions, the routes they generate, for the same pairs of origin and destination addresses, are different. Considering the current void in literature on WMAs and the routes they generate, in this paper, select common WMAs are compared and analyzed based on their routing techniques. The results of these comparisons will benefit researchers by helping them better understand the behavior of WMAs in producing routes, which in turn can be used for selecting suitable WMAs for research projects or developing applications (such as navigation and location-based services). The process in which routes are evaluated can also be used as a guideline to help researchers explore behavior of WMAs in generating routes. 相似文献

当前网络中存在多种在线地图服务,既有面向大众日常使用的各大互联网公司发布的在线地图服务,如百度地图、腾讯地图等,也有偏向于专业开发人员使用的ESRI和超图公司的在线地图服务,同时还存在目前各企事业单位使用较多的天地图等服务。这些广泛使用的地图服务各有特点,适用于不同客户的具体使用场景和需求。在使用这些服务时,通常需要利用特定的API进行服务调用。若将这些不同来源的服务尽量整合成以统一的方式进行调用的方式,将大大减少不同场景下调用地图服务的开发成本,同时,也能丰富同一使用场景下可选的地图服务来源。 相似文献

Recent developments in data visualization, developer Application Program Interfaces (APIs), and web services reinforce a long American tradition of statistical mapping and innovation at the US Census Bureau. Consistent with other international statistical agencies, the Census Bureau has used contemporary innovations in statistical mapping and data visualization to disseminate national census results for over 14 decades. The US Census Bureau’s data products and analyses have enabled decision makers and the public to access census results quickly and easily. The new information technology environment requires the Census Bureau to more rapidly expedite these results and deliver mapping products to new customers as well as to its traditional data consumers. The Census API has empowered developers and commercial companies to test the limits of a new emerging world of big data solutions. This article presents some of the most recent data visualization products from the Census Bureau, including an expanding Data Visualization Gallery to merge geospatial information and statistics on the map. 相似文献

The Potential of Maps APIs for Internet GIS Applications 总被引:2,自引:0,他引:2
T Edwin Chow 《Transactions in GIS》2008,12(2):179-191
Since the launching of Maps Application Programming Interfaces (APIs) in 2005, many web developers, including geographers and non‐geographers, applauded the freely adaptable tools and used them to spawn numerous Internet applications. The success of the Maps APIs is largely attributable to its no‐cost policy, the availability of global data coverage, dynamic navigation, query capability, and ease of implementation. Despite its versatility in dynamic exploration of geographic data online, the existing Maps APIs lack Geographic Information System (GIS) functionalities compared to other Internet Mapping Services. The goal of this research was to review the potential of the Maps APIs for Internet GIS applications. This research employed the Google Maps API and developed a web prototype that disseminates spatial information of urban sprawl in Mundy Township, Michigan. The results revealed that both vector and raster data could be effectively represented by using the Maps API. Moreover, the Geographic Markup Language (GML) approach illustrated great potential for developing Internet GIS solutions around open specifications. This research suggested several potential solutions to expand the spectrum of GIS operations of the Maps APIs by incorporating the XML‐related technology and extending the JavaScript library. 相似文献
