This webinar is a general introduction to the UDS Mapper, a mapping and decision-support tool driven primarily from health center patient location data within the Uniform Data System (UDS). The UDS Mapper is a collaboration between the Health Resources and Services Administration (HRSA) and the American Academy of Family Physicians (AAFP) and is part of the HealthLandscape online mapping platform. This webinar will go over the basics of using the UDS Mapper, and is geared toward users who are new to the UDS Mapper or in need of a refresher. The webinar is open to the public and free of charge.
