How often are transportation products and services updated?

Updates are variable and since USGS obtains most transportation data from external sources, the frequency of updates depends on the release schedule of the source products. Typically these updates range from every few weeks (Federal Aviation Administration) to an annual update cycle (U.S. Census Bureau). Transportation map services are targeted for quarterly refresh cycles, while updated products are immediately available for download.
