4.3.1 Lookup Tables

The following tables are used to define lookup values for select boxes in the web application:

waypoint_symbol

Key-value pairs describing waypoint symbols. The key is written to waypoint entries when downloading GPX files.

track_color

Key-value pairs together with an HTML colour code. The ’key’ is written to track entries when downloading GPX files and the HTML colour code is used to render the tracks on the itinerary map page.

georef_format

Key-value pairs define how to format output of latitude and longitude values on the itinerary waypoint edit page. Format parameters are defined using the {%} symbol and have the following meanings:

• %d - degrees
• %m - minutes
• %s - seconds
• %D - zero prefix single digit degree values
• %M - zero prefix single digit minute values
• %S - zero prefix single digit second values
• %c - output the cardinal value, S, E, W or N
• %i - output a minus sign for W and S
• %p - output a minus sing for W and S and a plus sign for E and N

E.g. a format string of %d°%M’%S”%c would result in a lat/long value of ‘1.5,-2.5’ being displayed as 1°30’00”N 2°30’00”W

Scripts to create some values for these lookup tables are in the ./provisioning/schema folder;

• 60_waypoint_symbols.sql
• 40_path_colors.sql
• 50_georef_formats.sql

The default waypoint symbols and track colours are generally appropriate for Garmin devices. In fact, the colours are the only ones allowed by the Garmin Extensions XSD.
