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.     

     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). Some of the aspects will be major and some minor.

 Astrocartography  maps show lines representing major aspects to the four angles.

      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 the relocation chart, 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 angle in a relocated chart with  the same planet as an Astrocartography angular line in a particular location.

      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.
