Editing Countries
Contents
Solar Maps contains a single country file which contains information relating to country names, sizes and locations. It is possible for the user to edit, add or delete entries, and alter the conditions under which certain entries are written onto maps. The country file can also potentially be used to store information on other geographical features such as seas, oceans, desert regions etc. which can all also be plotted onto maps.

To edit information in the county file |
Select the “Edit Countries...“ item from the “Maps“ menu.
This will display the “Edit Countries” dialog box.
The information that is stored for each entry in the country file is
• |
Name - This name is what appears on the map. |
• |
Latitude - The latitude at which the name is to be plotted. See Entering Latitudes and Longitudes for a description of valid latitude formats. |
• |
Longitude - The longitude at which the name is to be plotted. See Entering Latitudes and Longitudes for a description of valid longitude formats. |
• |
Plot If <= - This controls how wide the map must be in order for the name to be plotted. For example, if a value of 100 is entered, then this name will only appear on maps which cover less than 100º of longitudinal width. If its value is set to 360º, then the area of the country (1000 km2) is used to determine whether the name is plotted, instead. |
• |
1000 km2 - This is the area of the country in thousands of square kilometres. If the Plot If <= field is set to any value other than 360, then this field is ignored. Otherwise this value is used to control whether the name is plotted on maps of various sizes. Names with large areas are plotted on all maps, with medium areas on smaller maps, and with small areas only on the smallest maps. This value may be set to zero if the actual area is unknown, or if the entry relates to a geographical feature which does not have an area. In this case, you can use the Plot If <= field to control on which maps the name is plotted. (Note: 1000km2 is equal to approx 386mi2.) |
Note that the “Zone...“ and ”Copy...“ buttons are disabled as they do not apply to the country entries.
