In addition to viewing the planetary lines of a natal chart over a map, an additional technique that can be used is to view the planetary lines of progressions, directions or transits to that natal chart. As these charts vary with time (ie. they are dynamic), it is possible to use this technique as a predictive tool, by looking at how planetary lines change over a period of time.
When a progressions, directions or transits chart is used to display planetary lines, it is necessary to retain the original chart angles from the natal chart, so that one can see how much planets have moved in relation to their natal positions. This is similar to the concept of a bi-wheel, where the progressed, directed or transiting chart is displayed around the natal chart, and where the house cusps remain fixed in relation to Ascendant and Midheaven of the natal chart.
As an illustration, consider the transiting Sun. This moves roughly 1º per day, so in relation to its natal position, it would have moved roughly half way around the world after 6 months, and have returned to its natal position after about one year. The secondary progressed Sun, however, moves only about one degree per year, so in relation to its natal position, it would have moved only about 30º after 30 years of life.
Solar Maps allows you to cast a chart for secondary progressions, tertiary progressions, solar arc directions, or for transits, for any specified date.
The method of CycloCartoGraphy®, also developed and registered by Jim Lewis, uses a mixture of transiting and secondary progressed planets. For a particular date, it uses the outer transiting planets (Jupiter, Saturn, Uranus, Neptune and Pluto) and the inner progressed planets (Sun, Moon, Mercury, Venus and Mars). Solar Maps includes this technique under the name “Sec.Prog + Transits (CCG)”. If you were to compare chart lines using this technique to those for secondary progressions and transits, you would see that the CCG lines for the inner planets correspond to the same secondary progressed lines, and the CCG lines for the outer planets correspond to the same transit lines.
An example: This example looks at John F. Kennedy’s transits at the time of his famous speech in 1963 at the site of the Berlin Wall that had been constructed by the East Germans in 1961, dividing the city in two. Kennedy, born May 29, 1917 at 3 pm in Brookline MA, visited Berlin on June 26, 1963 and, to show solidarity with the West Germans, declared Ich Bin Ein Berliner (I am a Berliner). Notice that on the day of his speech, transiting Mercury and Venus were setting and Jupiter was on the IC. Though not seen in the image above, the transiting Sun was setting in Moscow, where his natal Mars is on the IC. Also of note, his natal Venus sets in Western Europe, indicating that at the time of the speech he was experiencing a Venus return.
