Sphere-of-Influence Records: #s

     The outline of a region such as an empire can be shown in the map view with a "sphere-of-influence" record. Here is an example:

#bc
#s <n>Old Babylonian Empire<col>80 100 100<d>1800(100)<poly>"oldbab.poly"<e>1600(100)

The sample polygon has only one date interval, but it could have more. If you construct the polygons corresponding to the growth and decline of an empire, all of them can be linked into one sphere record by repeating the <d> and <poly> fields. Then end it with one <e> field.
