Transmittal Summary

The SEDRIS Data Representation Model APPENDIX A - Classes Transmittal Summary

Class Name: Transmittal Summary

Superclass - <SEDRIS Abstract Base>

Subclasses

This DRM class is concrete and has no subclasses.

Definition

An instance of this DRM class summarizes the content of the transmittal for which its aggregate <Transmittal Root> instance serves as root object, in terms of:

Environmental domains represented (such as, terrain, ocean)
Types of data used (such as geometry, features, data tables)
DRM classes used
EDCS Classifications used
Spatial reference frames used

Example

A <Transmittal Summary> for a transmittal containing a <Model Library> and an <Environment Root>.

FAQs

How are the environmental domains summarized?: The <Transmittal Summary> can aggregate a list of <Environmental Domain Summary> instances. Each <Environmental Domain Summary> represents one of the domains for which data is provided.
How are the SEDRIS classes used summarized?: The <Transmittal Summary> can aggregate a list of <DRM Class Summary Items>. Each <DRM Class Summary Item> represents one of the classes used.
How are the classifications summarized?: Each classification (i.e. the ECC and the sets of EACs used with it) that is used in the transmittal is summarized using a <EDCS Use Summary Item>. Each <EDCS Use Summary Item> is a component of the <DRM Class Summary Item> that represents the class that uses the classification within the transmittal.
How are the spatial reference frames summarized?: Each spatial reference frame that is used in the transmittal is summarized using a <SRF Summary>. Each <SRF Summary> is a component of the <DRM Class Summary Item> that represents the class that uses the spatial reference frame within the transmittal.

Notes

Fields Notes

data_tables_present

 This indicates whether <Data Table> instances of some kind are present
 in the transmittal being summarized, and if so, in what context.

priority_values_present

 This indicates whether <Rendering Priority Level> instances are present
 somewhere in the transmittal being summarized, and if so, in what
 context.

mobility_values_present

 This indicates whether <Property> instances exist somewhere in the
 transmittal, the EAC codes of which specify mobility, a.k.a.
 trafficability, information, such as
 EAC_SURFACE_TRAFFICABILITY_GROUP_SIMNET.

colours_present

 This indicates whether <Colour> instances are present in the
 transmittal being summarized. If no <Colour> instances are
 present, the value of the colour_model field is not applicable.

colour_model

 Interpreted by the Level 0 API only if colours_present is set to
 SE_TRUE.

 The colour model used by the data provider for all <Colour> instances
 in the transmittal. For instance, if this field's value is
 SE_CLR_MDL_RGB, then any <Colour Data> instance in the transmittal
 shall be an <RGB Colour>; otherwise, the transmittal is invalid.

EDCS_usage_list_is_comprehensive

 whether <EDCS Use Summary Item> is comprehensive
