Class ISO6709

java.lang.Object

org.apache.tika.parser.mp4.boxes.ISO6709

public final class ISO6709
extends Object

Parses ISO 6709 location strings as written in QuickTime/MP4 metadata: the udta "©xyz" box and the com.apple.quicktime.location.ISO6709 value. Returns the latitude, longitude and optional altitude.

Both the decimal-degree form (e.g. +12.3456-098.7654+010.500/) and the ISO 6709 sexagesimal compact forms (±DDMM.MMMM / ±DDMMSS.SSSS for latitude and the ±DDD... equivalents for longitude) are handled. The form is chosen by the integer-digit count of each angle, which is unambiguous for valid coordinates: a decimal latitude (|lat| <= 90) has at most 2 integer digits and a decimal longitude (|lon| <= 180) at most 3, so neither can collide with the 4/6 (latitude) or 5/7 (longitude) integer-digit counts of the minute/second forms. Any other digit count falls back to a lenient decimal parse.
