摘要:
Interactive geographic information systems (GIS) and techniques are disclosed that provide users with a greater degree of flexibility, utility, and information. A markup language is provided that facilitates communication between servers and clients of the interactive GIS, which enables a number of GIS features, such as network links (time-based and/or view-dependent dynamic data layers), ground overlays, screen overlays, placemarks, 3D models, and stylized GIS elements, such as geometry, icons, description balloons, polygons, and labels in the viewer by which the user sees the target area. Also, “virtual tours” of user-defined paths in the context of distributed geospatial visualization is enabled. Streaming and interactive visualization of filled polygon data are also enabled thereby allowing buildings and other such features to be provided in 3D. Also, techniques for enabling ambiguous search requests in a GIS are provided.
摘要:
A geographic information system and method that facilitate the display of user-annotated datasets. The dataset can include data such as user-generated videos, photos, blogs, etc., and is processed to search for geo-annotations. The geo-annotations and other data signals are utilized by a scorer to determine a level-of-detail for the particular data. The level-of-detail provided by the scorer is utilized by the geographic information system to determine which data to display as a user navigates around a map.

摘要:
Data-driven guarded evaluation of conditional-data associated with data objects is used to control activation and processing of the data objects in an interactive geographic information system. Methods of evaluating conditional-data to control activation of the data objects are disclosed herein. Data structures to specify conditional data are also disclosed herein.
摘要:
A computer-readable medium having stored thereon an applications programming interface for causing a computer system to render a three-dimensional scene according to a downloaded file. A scene graph is constructed from a number of objects stored in memory. These objects have variables which can be changed by subroutine calls. Furthermore, one or more objects can contain one or more fields. A field is comprised of a data type which represents the state of an object. Engines are used to perform defined functions to the fields. One or more routes can be used to change one field in response to changes made to another field. A class hierarchy is defined to implement a retained mode graphics.

摘要:
A packet-spreading data transmission system with anonymized endpoints facilitates enhanced fortified private communications between a plurality of arbitrary devices via a plurality of communication channels or networks. The data transmission system receives at a source endpoint device a message of arbitrary length. The message includes a destination address associated with a destination endpoint device. Both source endpoint device and the destination endpoint device are selected from a plurality of arbitrary devices. The received message are fragmented and agilely transmitted, via a plurality of communication channels, from the source endpoint device to the destination endpoint device.
摘要:
An electrical grounding arm is described and which has a predetermined geometry that dissipates stress imparted to the electrical grounding arm by the repeated movement of the electrical grounding arm, so as to inhibit stress related damage from being imparted to the electrical grounding arm, and which further, inhibits a source of fluid from pooling or collecting on the exterior facing surface thereof in order to prevent an unsanitary condition from developing.
摘要:
A system for ranking geospatial entities is described. In one embodiment, the system comprises an interface for receiving ranking data about a plurality of geospatial entities and an entity ranking module. The module uses a ranking mechanism to generate place ranks for the geospatial entities based on the ranking data. Ranked entity data generated by the entity ranking module is stored in a database. The entity ranking module may be configured to evaluate a plurality of diverse attributes to determine a total score for a geospatial entity. The entity ranking module may be configured to organize ranked entity data into placemark layers.
