Implications and caveats

Severity: Comment

  • Higher levels of coordinate precision (more than six decimal places indicating a precision to less than 1m square) are generally not valuable for biodiversity occurrence records. Rounding to 6 decimal places simplifies some processing.
  • This article helps to explain the areas expressed by different decimal places for decimal coordinates: https://www.explainxkcd.com/wiki/index.php/2170:_Coordinate_Precision
