Abstract: The present invention discloses an apparatus and method for protecting digital spatial information. The apparatus for protecting digital spatial information according to the present invention includes a spatial information authority database which stores access authority information on spatial information, an access authority determining unit which, when there is a request for access to the spatial information from a user, determines whether to permit the user to access the requested spatial information by referring to the spatial information authority database, a spatial information database, a spatial information providing unit which obtains the access-permitted spatial information from the spatial information database, organizes the information based on the user's request for access, and provides the information, and an access control unit.

Abstract: The method includes generating a 3D facility model for time-series information mapping using a 3D facility model, receiving input information on a desired time-series information type and a time-series information showing method, retrieving time-series information required to be visualized on the basis of the input information on the time-series information type and the time-series information showing method, mapping the retrieved time-series information to the generated 3D facility model according to the input time-series information showing method, and integratedly visualizing the 3D facility model and the time-series information mapped to the 3D facility model. When the apparatus and method are used, household-specific time-series information is precisely mapped and visualized to the corresponding 3D positions of a 3D spatial model, so that the time-series information in a 3D virtual city model can be integratedly visualized.

Abstract: Provided are an apparatus and method of providing facility information that may correct inaccurate information on a facility using site information and provide the corrected information in an augmented reality manner. A facility information providing apparatus according to an exemplary embodiment of the present invention including: a site information analyzing unit that analyzes site information to identify a site facility; a facility information searching unit that retrieves facility information corresponding to the site information; a facility information mapping unit that maps the facility information with the site facility and corrects the facility information based on a mapped result to generate corrected facility information; and an augmented reality providing unit that synthesizes the corrected facility information with the site information to generate augmented reality information.

Abstract: The present invention relates to an apparatus and a method for searching for an open API and generating a mashup block skeleton code. A method for searching for an open API and generating a mashup block skeleton code includes: storing metadata of web services and open APIs according to an integrated schema; searching for a web service or an open API corresponding to search query input from a user; extracting the metadata necessary to generate the skeleton code of the metadata of the mashup block by using the mapping relationship between the meta data of the searched web service or the searched open API and the metadata of the mashup block; and generating the skeleton code of the metadata of the mashup block by using the extracted metadata.

Abstract: The present invention relates to an apparatus and a method for automatic mash-up, and more particularly, to an apparatus and a method for automatic mash-up for providing new services by combining previously constructed services providing an open application programming interface (API). The automatic mash-up apparatus according to an exemplary embodiment of the present invention includes: a mash-up execution unit executing a mash-up service comprised of two or more open applications; a service context inference engine unit inferring changes in service context of the mash-up service; and a mash-up management control unit reorganizing the mash-up service in accordance with an inference result of the service context inference engine unit.

Abstract: Disclosed is an apparatus and a method for creating textures of a building capable of storing textures of a three-dimensional building automatically extracted/obtained from spatial information convergence contents such as photographs, moving pictures, etc., including positional information and directional information, etc. together with a three-dimensional spatial information model.

Abstract: Provided is a distributed constant type filter. In a stacked body formed by stacking a plurality of printed circuit boards, signal line coil patterns on adjacent printed circuit boards face each another and are electrically connected together at both ends, and ground line coil patterns on adjacent printed circuit boards face each other and are electrically connected together at both ends. Accordingly, the distributed constant type filter has an attenuation characteristic superior to conventional distributed constant type filters while having an equivalent circuit completely different to the conventional distributed constant type filters. In addition, attenuation characteristics can be obtained without being greatly affected by a deviation upon a manufacturing process, and a process of manufacturing the filter is simple.
