Relocation astrology looks at how planets are in aspect to the Ascendant, Descendant, Midheaven (Mc) and Imum Coeli (Ic).     The Ascendant is the most eastern point looking over the horizon. The Descendant is the most western point. The Midheaven is the highest point admidst the twelve signs of the zodiac. The Imum Coeli is the lowest.       Astrocartography maps show lines representing ONLY the conjunct aspect to the four angles.         Relocation charts show aspects to the four angles in the chart, Ascendant, Descendant, Imum Coeli, and Midheaven (1st, 4th, 7th and 10th house cusp lines). Aspects revealed will be major AND  minor.  Support or lack of support of Astrocartography lines from other aspects in the relocated chart are made clear.      If you are looking for love and you go to a Venus line and Pluto is squaring it your theme can be one of love, but with discomfort. In this sense Astrocartography can provide only part of the story.

      The Ascendant in an Astrocartography map is different than the Ascendant in a relocated chart.  This happens because Astrocartography maps are calculated in relationship to the equator and relocation charts, as in the standard natal birth chart are calculated in relationship to the ecliptic. (The ecliptic is the imaginary path the sun appears to make as though it was circling around the earth throughout the year).

      If you were to place planetary (zodiacal) lines based on their latitudes in relationship to the ecliptic you would find a shifting would occur in relationship to the planetary (mundo) lines positioned in relationship to the Astrocartography Ascendant-Descendant axis, which uses only a zero degree latitude off the equator.

      So latitude variations of planets can show up when comparing a planet on an Ascendant or Descendant angle in a relocated chart with the same planet as an Astrocartography Rising or Setting line in a particular location.  The planets that have the highest latitudes that show the variation are Pluto, Venus and the Moon. Pluto always shows variation up to 6 degrees. Venus can vary as much as 3 degrees. The Moon can vary up to 1 degree. Mars and Mercury can vary, but the occurrence does not happen as often. When it does Mars can vary about 2 degrees and Mercury less than 1 degree.

     The differences between Astrocartography mapping and relocation charts can produce different results. 

     They both provide results that are very informative when assimilated in their own right. Then it is up to the reader to put the mosaic together.
