This booklet explains the techniques behind Astro Map Analysis. The house cusps of a horoscope are determined by time of birth and place (latitude and longitude). Often, people have moved from their birthplace. We never lose our natal chart; it is always symbolic of our basic character and tendencies. But we can get additional information from the location we now inhabit (or about localities we might consider). By using the birth data for an Astrolocality Map, a person can determine if the present location is a good place to be, or if another location may have more advantages.
