Country Rank
The 'Country Rank' tab-page give access to the Country Ranking facility.
Country Ranking Explained
There is never enough room on a world map to show all of the labels, so some form of Ranking must be used to set an order of label preference.
The 'Time Mapper UHD' ranks countries by their population, and shows labels for countries, capital cities, Amateur Radio callsign-prefixes, and flags for the larger countries first. As the software includes anti-overlap routines for labels in the same map-layer, this means that labels with a lower rank will not be shown if a label with a higher rank would overlap it.
A ranking by population may not please everyone, of course, so facility is provided for the User to set his own ranking order. There are two independent lists: one for Standard Countries, and the other for Ham Radio Countries. If you wish to change the ranking of a country, just select 'Standard Countries' or 'Ham Radio Countries' first, then select the country in the list, then choose a new position for it with the 'Ranking' control, then click 'Change Rank to New Value'. You can revert all changes by clicking the 'Restore All Ranks to Default Values' button.
