One of the most important datasets that MCDC’s partner MSDIS (Missouri Spatial Data Information Service) maintains is a series of interactive maps of the journey that Meriwether Lewis and William Clark took through Missouri in 1804 as the first leg of their now famous expedition to the Pacific Northwest.
Missouri Census Data Center partners with MSDIS on mapping and data projects. MSDIS is a spatial data retrieval and archival system offering many mapping resources, primarily focused on the state of Missouri.
