| Abstract: | There are many technical difficulties to discover and integrate geospatial information from web-based data considering its the ubiquitousness, diverse forms and structures. In this review, we first analyze the classification and characteristics of web-based ubiquitous geospatial information, upon which we systematically investigate the current progress of the discovery and integration technology. Here, the development status of discovery technology are summarized from four aspects of fast and accurate service discovery, deep network data collection with high coverage, location information extraction from unstructured text, and spatial semantic extraction of associated images. Subsequently, we analyze and explore the development trends of integration technology application to the matching and association of heterogeneous geometric data, address standardization, semantic alignment of homonymy entities, geographic entity relationships construction. Finally, we prospect the application of web-based ubiquitous geospatial information discovery and integration technology in many aspects such as open geospatial data network, urban governance and emergency management, network monitoring and geospatial intelligence. |
