Metadata for UNGABASIN This coverage contains the outlines of drainages basins defined by the locations of collected stream-sediment and heavy-mineral-concentrate samples as shown in the ungaseds_pts and ungaconc_pts point coverages. Drainage basin coverage is limited to that area within the Unga map extent (see ungaclip.met). This is a network coverage and contains arc and polygon topology.

ORDER is the drainage basin order, 1 being first order and 2 being second order. No higher order drainage basins were sampled. ORDERLINK has a value of 2 from first drainage basins linked to second order basins within the sample set. The elemental field values equal 1 if the drainage basin had an anomalous stream-sediment analytical value and 2 if it had an anomalous heavy- mineral-concentrate analytical value in that element.
