How to keep MTDB current and of high quality?

• “Establish partnerships and acquire data from authoritative sources and update”

• Issues

– Different formats

– Varying positional and temporal accuracies

– Inconsistent attribution

– Over/under coverage

– No one system solution that allows partner involvement
