This webinar is a general introduction to the basic functions of the Uniform Data System (UDS) Mapper, a mapping and decision-support tool driven primarily from health center patient location data within the 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. The webinar is geared toward first time users or those who need a refresher. The webinar is open to the public and free of charge.
