To complete the example, the name of the GSModel Composite Material Table GSModelCMT that is associated with the above geocell is:
N62W162_D309_S001_T001_L00_U0_R0.xml
Note that this file is located at LOD 0, hence the value 0 for UREF and RREF. This will be explained later in chapter 5.
Finally, the geometry of the tiled 2D model corresponding to the above tile will be named: N62W162_D310_S001_T001_L07_U38_R102.flt
3.7 Navigation Library Dataset
The \CDB\Navigation\ folder is the root directory of the Navigation library which is composed of a single dataset.
1. NavData The purpose of the Navigation library is to include all of the information which is either not
geographically located, or has a global geographical coverage and can be used as a lookup to the Navigation Tile-LODs.
3.7.1 Navdata Structure
The NavData dataset is assigned dataset code 400 and has a single level directory structure.
