501 results about "Spatial database" patented technology

A spatial database is a database that is optimized for storing and querying data that represents objects defined in a geometric space. Most spatial databases allow the representation of simple geometric objects such as points, lines and polygons. Some spatial databases handle more complex structures such as 3D objects, topological coverages, linear networks, and TINs. While typical databases have developed to manage various numeric and character types of data, such databases require additional functionality to process spatial data types efficiently, and developers have often added geometry or feature data types. The Open Geospatial Consortium developed the Simple Features specification (first released in 1997) and sets standards for adding spatial functionality to database systems. The SQL/MM Spatial ISO/IEC standard is a part the SQL/MM multimedia standard and extends the Simple Features standard with data types that support circular interpolations.

Computer-implemented automated building design and modeling and project cost estimation and scheduling system

A computer-implemented automated building design and modeling and construction project cost estimating and scheduling system (“DMES system”) is described. The DMES system provides a central source for all of the design and construction information for a construction project in a coordinated two-dimensional and three-dimensional spatial database that is freely accessible by all of the members of an interdisciplinary construction project team as a means to produce automatically coordinated design development and construction document information. The DMES system acquires and stores all of the appropriate design, engineering, and construction expertise and information available for any building type for use in automatically assembling and coordinating the design, cost-estimating, and scheduling for a construction project. In one embodiment, the DMES system consists of a plurality of objects, comprising elements and massing elements arranged in an assembly hierarchy. Each of the objects includes programming code that defines an interface and discrete internal functions that define its behavior. When instantiated in the database, the objects automatically create further instances of other objects in the hierarchy, which in turn do the same, thus assembling a complete building model automatically from the initial manually-placed instance. The building model enables automatic generation of drawings and cost and scheduling information. By running automatic iterations of the building model, multiple designs may be evaluated to determine the optimum design.

Office management solution

A spatial database interface for generally managing assets in a graphical user environment is disclosed, in the particular context of a CAOM office management software solution for managing office facilities inclusive of office layouts (equipment, furniture, information technology assets and other assets) and basic human resources within a physically-defined office space. The software is a web-based custom map application that links a relational database to an SVG or browser rendering format layout map that shows physical locations and relationships among people, rooms and other assets. It imposes a graphical user interface for point-and-click identification of the assets, reporting and reconfiguration (for “what-if” scenarios), and drag-and-drop manipulation of the assets. The software is resident on a web-enabled server hosted by an application service provider. The assets are associated with asset data stored in a web-enabled database and are linked to corresponding visual icons represented on the layout map by embedded HTML elements such as IFrames. All asset data is stored in the database, and robust searching, analysis and reporting capabilities are provided to employ the data.

Method and apparatus for precisely identifying effective addresses associated with hardware events

A system and method for precisely identifying an instruction causing a performance-related event is disclosed. The instruction may be detected while in a pipeline stage of a microprocessor preceding a writeback stage and the microprocessor's architectural state may not be updated until after information identifying the instruction is captured. The instruction may be flushed from the pipeline, along with other instructions from the same thread. A hardware trap may be taken when the instruction is detected and / or when an event counter overflows or is within a given range of overflowing. A software trap handler may capture and / or log information identifying the instruction, such as one or more extended address elements, before returning control and initiating a retry of the instruction. The captured and / or logged information may be stored in an event space database usable by a data space profiler to identify performance bottlenecks in the application containing the instruction.

High-performance location management platform

An apparatus and method for rapid translation of geographic latitude and longitude into any of a number of application-specific location designations or location classifications, including street address, nearest intersection, PSAP (Public Safety Answering Point) zone, telephone rate zone, franchise zone, or other geographic, administrative, governmental or commercial division of territory. The speed of translation meets call-setup requirements for call-processing applications such as PSAP determination, and meets caller response expectations for caller queries such as the location of the nearest commercial establishment of a given type. To complete its translation process in a timely manner, a memory-stored spatial database is used to eliminate mass-storage accesses during operation, a spatial indexing scheme such as an R-tree over the spatial database is used to locate a caller within a specific rectangular area, and an optimized set of point-in-polygon algorithms is used to narrow the caller's location to a specific zone identified in the database. Additional validation processing is supplied to verify intersections or street addresses returned for a given latitude and longitude. Automatic conversion of latitude-longitude into coordinates in different map projection systems is provided. The memory-stored database is built in a compact and optimized form from a relational spatial database as required. The R-tree spatial indexing of the memory-stored database allows for substantially unlimited scalability of database size without degradation of response time. Maximum performance for database retrievals is assured by isolating the retrieval process from all updating and maintenance processes. Hot update of the in-memory database is provided without degradation of response time.
