Questions Regarding Base Material and Composite Material Tables

2008-11-11T17:58:16Z

I’d like to have a phone discussion with the best technical POC regarding this subject. Could you please contact me at 330.796.4890.

Thanks!

CDB 3.0 Draft 2 - Appendix F

2008-11-19T15:13:18Z

This pertains to CDB 3.0 specification draft 2.

Page 3-1 references the appendices for various hierarchy specific information. Of particular interest was:

- Appendix F lists all of the 3D Model component naming and hierarchy of the
CDB

I checked Appendix F in the CDB Specification - 02 - Appendices.pdf, but this seems to repeat the data in Appendix O which is related to Model Skin Names.

Will there be a new draft published soon that will contain this appendix?

Thank you.

Does the CDB support snow sensor texture?

2008-06-16T10:05:33Z

I have a looked through the spec and can’t see any reference to snow sensor texture. If I change from summer to winter I would need to update the FLIR image accordingly. Am I right in thinking it would involve more than just changing the material values, and a different sensor texture would be required?

1. 6.1.1.1 Visible Spectrum Terrain Imagery (VSTI) Components
The VSTI component provides the visible spectrum imagery that is orthographically draped over the terrain skin generated from Primary Terrain Elevation Dataset. The CDB specification provides a flexible means to store and retrieve the VSTI components in accordance to time of year. There are three ways to organize VSTI components of the Imagery Dataset:
1. Yearly: The first approach requires a single, year-round representation of the terrain imagery.
2. Quarterly: The second approach requires four variants of the terrain imagery, one per season. In the case of a missing variant, simulator client-devices are required to select the closest variant (in-time).
3. Monthly: The third approach requires monthly-variants of the terrain imagery, one per month. In the case of one or more missing variants, simulator client-devices are required to select the closest variant (in-time).

All three approaches can be stored individually or in combination within the CDB.

004 *.TIF,
*.JP2 Alternate VSTI
Winter representation Winter equivalent of above, i.e., this is the preferred Dataset Component for springtime representative terrain imagery. Can be used interchangeably with all other Alternate VSTI representations.

Can the repository cope with multiple data copies of the same geographic area.

2008-06-12T08:56:23Z

the press release states that the CDB is a single-copy data repository, but can it cope with multiple copies that may be required for different security classifications? For example, UNCLASSIFIED and SECRET versions of the same geographic area depending upon the customer requirement.
