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.

Entity display priority in a distributed geographic information system

Provided is a single repository for capturing, connecting, sharing, and visualizing information based on a geographic location, for example. Detailed information of a structure or object information can be displayed on a rooftop or over an area of interest. The detailed information can be provided for a single structure or for each structure shown on a map area. According to an embodiment is a system that facilitates surface overlay and bounding on a map. The system can include a receiver component that receives information for an object, a boundary component that ascertains a perimeter of the object, and a rendering component that selectively displays the object information and object on a map based in part on a user perspective.

Virtual earth rooftop overlay and bounding

Provided is a single repository for capturing, connecting, sharing, and visualizing information based on a geographic location, for example. Detailed information about a structure or other object information can be displayed as mode information. An object of interest can be identified by monitoring a user activity or inactivity with regard to a displayed map. If the user hovers a pointing device over an object within the displayed map for longer than a predetermined amount of time, it can be inferred that the user should be presented with additional information regarding the object.

Mode information displayed in a mapping application

Provided is a single repository for capturing, connecting, sharing, and visualizing information based on a geographic location, for example. Detailed information can be dynamically rendered as a function of a user parameter, which can include a user demographic, a user profile, and a user preference information. Map information and advertisements displayed in conjunction with the map information can be dynamically rendered as a function of a user advertising preference. If a user prefers one product over another product, a first advertisement for the less preferred product can be replaced with a second advertisement for the preferred product.

PROBLEM TO BE SOLVED: To automatically generate a three-dimensional homogeneous structure shape, at low cost. SOLUTION: An automatic generation apparatus that automatically generates a three-dimensional structure shape based on a plurality of points having three-dimensional coordinates containing height information includes means to structure a point group by collecting points within a predetermined threshold, based on distances between two or more points forming a three-dimension or two-dimensional distances and height differences between two or more points, means with respect to the point group, to extract a coefficient value of a function to minimize an error concerning the point group, by using height information z of the point group (z>0) and a predetermined function, and means to generate a shape of a three-dimensional structure based on the coefficient value. The means to generate a shape of a three-dimensional structure based on the coefficient value calculates one or more coefficient values in a power series function of one or more degree or a linear combination function of an elementary function, by performing a least square method, and generates a roof shape of the three-dimensional structure, using a size relation of the coefficient values.
