ISO/TS 19163-1:2016 地理情報—画像およびグリッドデータのコンテンツコンポーネントとエンコードルール—パート1：コンテンツモデル | ページ 6

4.1

attribute

named property of an entity

Note 1 to entry: Describes a geometrical, topological, thematic, or other characteristic of an entity.

[SOURCE:ISO/IEC 2382:2015, 2121440, modified — Note 1 to entry has been added.]

4.2

binding

specification of a mapping relating the information defined in a content model (4.3) (data and metadata) to the data format that carries that information

4.3

content model

information view of an application schema

Note 1 to entry: In this Technical Specification, a content model describes the required content components and their interrelationship of imagery (4.12) and gridded thematic data (4.14) .

[SOURCE:ISO/TS 19129:2009, 4.1.2, modified — Note 1 to entry has been added.]

4.4

conversion rule

rule for converting instances in the input data structure to instances in the output data structure

[SOURCE:ISO 19118:2011, 4.7]

4.5

encoding rule

identifiable collection of conversion rules (4.4) that define the encoding for a particular data structure

Note 1 to entry: An encoding rule specifies the types of data to be converted as well as the syntax, structure and codes used in the resulting data structure.

4.6

fused image

image produced by fusing images from multiple sources

4.7

geopositioning

determining the geographic position of an object

[SOURCE:ISO/TS 19130:2010, 4.36, modified]

4.8

georectified

corrected for positional displacement with respect to the surface of the Earth

[SOURCE:ISO 19115‑2:2009, 4.12]

4.9

georeferenceable

associated with a geopositioning (4.7) information that can be used to convert grid (4.10) coordinate values to values of coordinates referenced to an external coordinate reference system related to the Earth by a datum

4.10

grid

network composed of two or more sets of curves in which the members of each set intersect the members of the other sets in an algorithmic way

[SOURCE:ISO 19123:2005, 4.1.23, modified]

4.11

gridded data

data whose attribute (4.1) values are associated with positions on a grid (4.10) coordinate system

Note 1 to entry: Gridded data are a subtype of coverage data, which represent attribute values of geographic features in terms of a spatial grid.

[SOURCE:ISO 19115‑2:2009, 4.17, modified — Note 1 to entry has been added.]

4.12

imagery

representation of phenomena as images produced by electronic and/or optical techniques

Note 1 to entry: The term imagery is often used colloquially with various meanings in different contexts. It is often used to describe any set of gridded, point set or other form of coverage data that can be portrayed.

[SOURCE:ISO/TS 19101‑2:2008, 4.14, modified — Note 1 to entry has been added.]

4.13

looks

groups of signal samples in a SAR processor that splits the full synthetic aperture into several sub-apertures, each representing an independent look of the identical scene

Note 1 to entry: The resulting image formed by incoherent summing of these looks is characterized by reduced speckle and degraded spatial resolution.

4.14

thematic data

gridded data (4.11) whose attribute (4.1) values describe characteristics of a grid (4.10) coverage feature in a grid format

Note 1 to entry: Most gridded thematic data are derived from imagery (4.12) data using geophysical/atmospheric inversion algorithms. Gridded thematic data may also be obtained from other sources such as digitization of topographic map sheets.

4.15

ungeoreferenced grid

gridded data (4.11) that does not include any information that can be used to determine a cell’s geographic coordinate values
