I have an XSD that requires me to use a BigDecimal for a lat/lon. I currently have the lat/lon as doubles, and convert them to BigDecimal, but I am only required to use about 12 places of precision. I have not been able to figure out how to set that. Can anyone help me with this?

You can use setScale() e.g.

double d = ...
BigDecimal db = new BigDecimal(d).setScale(12, BigDecimal.ROUND_HALF_UP);
