Entity and Attribute Information -- What geographic information (roads, houses, elevation, temperature, etc.) is included? How is the information encoded? Were codes used? What do the codes mean?

 


entity instance -- a spatial phenomenon of a defined type that is embedded in one or more phenomena of different type, or that has at least one key attribute value different from the corresponding attribute values of surrounding phenomena (e.g.

Entity: Geographic feature that exists and is distinguishable in the real world. For example, a land parcel, road, building, manhole, or pole.

identity
The topological overlay (input) with a polygon coverage (identity). For each feature in the input coverage, the intersection with identity features is determined, creating new features of the same feature class as the input coverage.

ENTITY CLASS
A specified group of real-world things, for example, a road network.

Entity-relationship modeling (E/R modeling) - An approach of data modeling that aims to identify the entities of interest and their relationships in database design. The major tool for E/R modeling is the Entity-relationship diagram.

geographic entity
An entity or geographic feature that occupies a position in space about which data describing the attributes of the entity and its geographic location are recorded.

[software] An entity that displays text entered by a user or derived from another source for editing purposes.

Secondly, each entity will transmit BSM only. This OTA information offers no information about the constellation the GNSS device sees or how the solution was derived in terms of filtering or applied constraints.

identity The topological overlay of a coverage (input) with a polygon coverage (identity).

Publisher
The entity(s) responsible for facilitating availability of the resource, such as a publisher, distributor, or a corporate entity.

his element is not used by ADS, as it causes too much confusion amongst users.

Feature A representation of a geographic entity, as a point, line, or polygon. Figure-Ground A visual image consists of two distict elements: the figure that has shape or substance and the ground that forms a background for the figure.

Attribute: A fact describing an entity in a relational data model, equivalent to the column in a relational table.
Base Map: A set of topographic data displayed in map form providing a frame of reference or contextual information to the user.

service A computation performed by a software entity on one side of an interface in response to a request made by a software entity on the other side of the interface.

A label is also needed to identify what the entity is. For example a section of railroad line could be represented by a line consisting of a starting and ending x, y coordinate and the label "railroad".

The request for location can originate in the client himself or in another entity such as application provider or network operator. In any case, whenever location is requested the customer has to give permission for the location request.

Postmodernism A still tenuous attempt to lend identity to a new era beginning in the early 1970s which is associated with changes from and reaction to certain attributes of modernity or modernism.

An object is a collection of data elements and operations that together are considered a single entity. The object-oriented database is a relatively new model.

GRASS defines a vector area as composite entity consisting of a set of closed boundaries and a centroid. The centroids must contain a category number (see v.centroids), this number is linked to area attributes and database links.

The Group Agents are associated with sets of polygons ordered by geometric patterns (polygon clusters, sequence of polygons along a fictive line), thematic identity or similarity, topologic partition, or geographic regions.

"science side" of the GIS-L discussion (Table 1) spoke mainly about the use of GIS as a method or body of knowledge for developing and testing spatial theories (Brenner 1993; Laffey 1993; Sandhu 1993b; Wright 1993a), not about the physical entity GIS ...

The US Census Bureau has released the 2003 TIGER/Line files by county or statistically equivalent entity based on the latest available governmental unit boundaries (January 1, 2003).

Geometric representation of a surface; entity that is composed of a line or a series of lines used for its delineation. A polygon on the earth as projected onto a horizontal plane is an example of an area.

Find is a function which allows the user to find a specific spatial entity, such as the name of the owner of the parcel.

"The ability to create 3D model forms in V8i during very early design phases using basic solid entities, and then tune them using the 'modify solid entity' tool, is a great step ahead.

Feature - A spatial element which represent a real-world entity by having specific characteristics. Often used synonymously with the term object. A generalized description of a point, line or polygon.

Using ArcGIS for AutoCAD, you can right-click any AutoCAD entity encoded with the mapping specification for drawings attributes and use the standard AutoCAD properties dialog box to view and modify them.

The sequential transmission of the signal elements of a group representing a character or other entity of data.

Line 1. set of ordered coordinates that represents the shape of a geographic entity too narrow to be displayed as an area (e.g., contours, roads, and streams). A digital line begins and ends with a node.
2. A line on a map (e.g., a neatline).
