Table 3-13: GTModelInteriorTexture Directory Structure
Director y
Level Directory
Name Description
Level 1 507_GTModelInteriorTexture
The name of the directory is composed of the dataset code
followed by an underscore and the dataset name.
Level 2 A
The name of the directory corresponds to the first character of
texture name TNAM, in uppercase.
Level 3 B
The name of the directory corresponds to the second character
of texture name TNAM, in uppercase.
Level 4 TNAM
The texture name has from 2 to 32 characters. The first two characters
are alphanumeric.
3.4.4.1 GTModelInteriorTexture Naming Convention
Requirement 54
http:www.opengis.netspeccdbcore1.0gtmodelinteriortexture-name
The names of the GTModelInteriorTexture files SHALL adhere to the following naming convention:
D507_Snnn_Tnnn_LOD_TNAM.rgb
The following table defines each field of the file name and Table 5-8 provides the values of the Component Selectors to complete the name.
Table 3-14: GTModelInteriorTexture Naming Convention
Field Description
D507 Character D followed by the 3-digit code assigned to the dataset
Snnn Character S followed by the 3-digit Component Selector 1

Tnnn Character T followed by the 3-digit Component Selector 2
LOD The Level of Detail corresponding to the Texel Size of the texture as
explained in section 3.3.8.5. TNAM The texture name; identical to the folder name where the texture resides.
rgb The file type associated with the dataset SGI Image
3.4.4.2 GTModelInteriorMaterial Naming Convention
Requirement 55
http:www.opengis.netspeccdbcore1.0gtmodelinteriormaterial-name
The names of the GTModelInteriorMaterial files SHALL adhere to the following naming convention:
D509_Snnn_Tnnn_LOD_TNAM.tif
The following table defines each field of the file name and Table 5-9 provides the values of the Component Selectors to complete the name.
Table 3-15: GTModelInteriorMaterial Naming Convention
Field Description
D509 Character D followed by the 3-digit code assigned to the dataset
Snnn Character S followed by the 3-digit Component Selector 1
Tnnn Character T followed by the 3-digit Component Selector 2
LOD The Level of Detail corresponding to the Texel Size of the texture as
explained in section 3.3.8.5. TNAM The material texture name; identical to the folder name where the
material texture resides. tif
The file type associated with the dataset currently specified as a TIFF file
3.4.4.3 Example 1
The following example illustrates the directory structure that would store all LODs of a texture whose name is BeigeGypseWall:
\CDB\GTModel\507_GTModelInteriorTexture\B\E\BeigeGypseWall\
Where \CDB\GTModel is the root of all geotypical model datasets, \507_GTModelInteriorTexture is the directory containing all geotypical interior textures, \B is
the directory containing all textures whose name start with the letter B, \R is the directory

containing all textures whose name start the letter ‘B’ followed by the letter ‘E’, and \BeigeGypseWall is the directory containing all LODs of the texture representing a beige gypse
wall. Note that the second letter of the texture name is a lowercase ‘e’ but the corresponding directory name is an uppercase ‘E’.
If the texture has a resolution of 1 cm and a dimension of 256 x 256 pixels, the finest LOD will be 10 and the coarsest will be 2, and the following files would be found in the above directory:
D507_S001_T001_L02_BeigeGypseWall.rgb D507_S001_T001_L03_BeigeGypseWall.rgb
D507_S001_T001_L04_BeigeGypseWall.rgb D507_S001_T001_L05_BeigeGypseWall.rgb
D507_S001_T001_L06_BeigeGypseWall.rgb D507_S001_T001_L07_BeigeGypseWall.rgb
D507_S001_T001_L08_BeigeGypseWall.rgb D507_S001_T001_L09_BeigeGypseWall.rgb
D507_S001_T001_L10_BeigeGypseWall.rgb
