ZENRIN CO., LTD. was founded in 1948 in Beppu, Oita Prefecture, Japan as a publisher of tourist maps. From there, we began to develop precise residential maps, which proved to be a big hit due to the less-than-standard address system found in Japan. Our current residentialmaps cover 99% of Japan's cities, towns and villages.
In 1984 Zenrin developed an original, computer-based mapping system in order to provide high-quality information for general public use. Using this technology, we have successfully compiled a cartographic database of Japan's major cities. This database is widely used in the GIS (Geographic Information Systems) software used by many corporations and municipalities.
Zenrin is also expanding its opportunities overseas by using original computerized mapping technology and know-how. In the People's Republic of China, Zenrin has opened cartographic data processing offices in Shanghai and Shenzhen. In Europe, the US, and Taiwan, Zenrin already produces navigation software, and this technology is being used with highly popular in-car navigation systems.
In the US, Zenrin provides navigation software and expertise to Nissan North America and other automobile and navigation systems hardware manufacturers. Zenrin is also continuing to explore collaborative efforts with other electronic and auto manufacturers. Zenrin surveys businesses along America's Interstate corridors to integrate into their navigation software. Businesses, organizations, and travelers nationwide utilize this data in a variety of applications and settings. In April 2000, Zenrin' s US branch was incorporated under the name ZENRIN USA, INC.
ZENRIN USA’s experienced field teams collect and verify data on an ongoing basis. Field teams use differential GPS (Global Positioning System) receivers to collect information that is necessary for navigation. Additionally, the field staff updates business and point of interest (POI) information so that it remains fresh and relevant to customers. Zenrin staff works with clients to verify pre-existing data sets to resolve any inconsistencies and ensure the highest quality information.
and this are the advantage that using computerized data base system by ZENRIN CO.
- A system and method can store and retrieve advance directives with a database that is coupled to a communications system. The database is arranged to register and store information about a service provider in anticipation of future creation of advance directives that will come into at least the temporary possession of the service provider. The database is arranged to store information supplied by the service provider and about a person and the person's advance directive. The communications system is operable in response to a request by the service provider to automatically transmit information about one or more advance directives that were stored in the database by the service provider.
- A method of providing interoperability between an open standard directory service and a proprietary database. The directory is represented as a mapping tree, consistent with directory service protocols such as X.500 or LDAP. The mapping tree node associated with the proprietary database is configured as a null suffix mapping tree entry, so that database mapping tree node replaces root of the mapping tree and the proprietary database the default backend of the directory service. The core server of the directory service is configured to recognize the null suffix mapping tree entry. All directory service operations are routed to a pre-operation plug-in that handles operations in the proprietary database, and remaining operations are redirected to the core server, preserving default functionality of the directory service. Normal data constraints are suspended for operations performed in the proprietary database.
