coregistration

coregistration

(kō-rĕj″ĭ-strā′shŭn)
The correlation of anatomical and metabolic data from different imaging techniques (e.g., from a CT scan and a PET scan of the same organ) in order to obtain enhanced images of diseased tissues.

While selection of the optimal GPS receiver is a project-dependent consideration, the data we present is important for GIS managers to help them: (1) understand the differences in horizontal positional accuracy obtained from various GPS receiver types; (2) ensure coregistration of GPS-acquired features and satellite or aerial imagery; and (3) determine the appropriate GPS receiver to use to satisfy mapping scale requirements.
