3.4.1.2 GTModelGeometry Level of Detail Naming Convention

Requirement 47 http:www.opengis.netspeccdbcore1.0gtmodelgeometry-lod-name The files of the GTModelGeometry Level of Detail dataset SHALL be stored in level 5 of its directory structure. The names of the files SHALL adhere to the following naming convention: D510_Snnn_Tnnn_LOD_FeatureCode_FSC_MODL.flt 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 3-4: GTModelGeometry Level of Detail Naming Convention Field Description D510 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 This field is identical to the name of the LOD directory level 5 where the file is stored. FeatureCode Five-character feature code as defined in Section 1.5 FSC Three-digit integer representing the feature sub-code FSC as defined in Section 1.5 MODL 32-character Model Name String flt The file type associated with the dataset currently an OpenFlight file

3.4.1.3 GTModelDescriptor Naming Convention

Requirement 48 http:www.opengis.netspeccdbcore1.0gtmodeldescriptor-name The files of the GTModelDescriptor dataset SHALL be stored in level 4 of the 5-level directory structure presented above. The names of the files SHALL adhere to the 81 © 2016 Open Geospatial Consortium following naming convention: D503_Snnn_Tnnn_FeatureCode_FSC_MODL.xml 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 3-5: GTModelDescriptor Naming Convention Field Description D503 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 FeatureCode Five-character feature code as defined in Section 1.5 FSC Three-digit integer representing the feature sub-code FSC as defined in Section 1.5 MODL 32-character Model Name String xml The file type associated with the dataset

3.4.1.4 Examples

The following example illustrates the directory structure that would store the entry file of all geotypical buildings with a feature code of AL015: \CDB\GTModel\500_GTModelGeometry\A_Culture\L_Misc_Feature\ 015_Building\ Where \CDB\GTModel is the root of all geotypical model datasets, \500_GTModelGeometry is the directory containing all feature code categories, \A_Culture is the directory containing all feature code subcategories of category A named Culture, \L_Misc_Feature is the directory containing all feature types of category A and subcategory L named Misc_Feature, \015_Building is the directory containing all OpenFlight files representing geotypical buildings whose feature types are 015 named Building. Examples of files found in the above directory are: .\D500_S001_T001_AL015_004_Castle.flt .\D500_S001_T001_AL015_015_School.flt .\D500_S001_T001_AL015_021_Garage.flt .\D500_S001_T001_AL015_037_Fire_Station.flt .\D500_S001_T001_AL015_050_Church.flt 82 © 2016 Open Geospatial Consortium Note that all filenames start with a common portion D500_S001_T001_AL015 and that only their FSC and MODL portions vary. If the castle above AL015_004_Castle is represented with 3 levels of details, say LOD 3, 5 and 8, they would be stored in .\L03\, .\L05\, and .\L08\ giving file names such as these: .\L03\D510_S001_T001_L03_AL015_004_Castle.flt .\L05\D510_S001_T001_L05_AL015_004_Castle.flt .\L08\D510_S001_T001_L08_AL015_004_Castle.flt Again, the descriptor associated with the same castle AL015_004_Castle would be found in this file: .\D503_S001_T001_AL015_004_Castle.xml
