…This, the authors argue, has contributed to China rapidly overtaking the US in geospatial technologies and disciplines of all kinds. Nowhere is this clearer than with China's satellite navigation system, BeiDou, which has been gaining on the US's GPS system in accuracy. In 2023, a US government advisory board on GPS stated in a memo that GPS is now "substantially inferior" to BeiDou.
Like other cuts to public science made under the Trump administration, the losses from blows to this agency could be substantial. A 2012 analysis found that every taxpayer dollar spent on NGS's coastal mapping program returned $35 in benefits, while a 2019 report found that the NGS program that models gravitational fields would provide between $4.2 and $13.3 billion worth of benefit over 10 years. The private sector also relies heavily on public data provided by NGS. Some analyses project that the geospatial economy will grow to $1 trillion by the end of the decade. It's even more crucial, experts say, to have an updated spatial reference system in the US, as well as institutional knowledge of the basic science of how to measure and understand our Earth…
