The following support files should be used with the DTDB98 (i.e. DTM98 and ETB98) datasets:
- CARIS drawing support files (consists of 5 files)
- Autocad drawing support files (consists of 2 files)
- DTDB98 User's guide
- NB Map Index (available in 3 different formats)
CARIS Drawing Support Files
| File | Name | Brief Description |
| Etb1998a.col | Colour table file | The colour table file assigns colours (defined in the colour map file) to feature codes, theme numbers, and other feature tags. Thus this file defines the colours that will be used to draw the individual features in your map (i.e. roads will be drawn in red, etc.) |
| Etb1998b.cma | Colour map file | The colour map file contains information for defining the colours (in terms of hue, lightness, and saturation) available for use by CARIS. |
| Etb1998c.bin | Symbol file (Binary) | The symbol file contains more instructions for drawing symbols and fonts. It is available in both binary and ASCII format. We recommend that you copy the binary file (as opposed to the ASCII file) to your computer. |
| Etb1998c.dat | Symbol file (ASCII) | See above ... |
| Etb1998d.txt | Master file |
CARIS requires that every feature (e.g. roads, rivers, buildings) in the map is assigned an alphanumberic feature code. For example, the feature code for 2 lane, paved roads may be ROAD2LPAVED. The master file contains a list of the feature codes for the features in the SNB topographic maps. It also contains some plotting instructions for lines, symbols, and fonts that are assigned to each feature. |

If you wish to use the DTDB98 files (i.e. digital terrain model and topographic data) with CARIS, we recommend that you download the above support files and reference these files to the appropriate CARIS environmental variables.
