Cadastral Survey Dataset
IRI: https://linked.data.gov.au/def/csdm/container/CSD
The set of cadastral survey data necessary to integrate a cadastral survey into, or transfer survey observations from, a cadastral database. A CSD identifier may be used to reference a previous survey. This exists without adequate definition in both LandInfra and landXML
|
Scope Note
|
Cadastral Survey Datasets may reference data from previous surveys, the extracted subset for each relevant previous survey is contained within a separate CSD object referenced by the CSD being submitted. Implementations will determine how these make be packaged, conceptually referenced CSDs are seen as a property of any given CSD |

Surveyed Line
IRI: https://linked.data.gov.au/def/csdm/surveyfeatures/SurveyedLine
A line of survey between an instrument location and a target point Means a geometric object that has magnitude (or length) and direction. For a cadastral survey system the geometric object consists of a set of reduced survey observations between two survey points.
|
Scope Note
|
To keep consistent with the paradigm of a line existing between two points, and to avoid duplication of information the instrument location is a special type of feature with a point geometry that may have several related observations and a link to setup information. |

A Boundary Line is a feature whose geometry is a connected set of lines representing the common part of two polygons share this set of oriented lines. As a feature it can participate in topological relationships between features that may, or may not, have planar geometry representations, and observations about the nature of the boundary can be made. The inner and outer features may be swapped by inverting the orientation of the geometry primitive, thus a single orientable boundary line may be used to partially define boundaries of both touching features. An oriented linear ring geometry representation for the planar extend of a bounded feature may be calculated from the geometries of the set of boundary features, using the inward or outward topology to adjust orientation accoridingly.
