You cannot explicitly tell the SAS System to use an index that has been created in processing. The SAS System will determine the most efficient way to process a query or statement. /* MERGE TWO SMALL DATASETS USING AN INDEX */ DATA GAPINFO1 (INDEX=(CLTNUM)); SET TEMP.GAPINFO; RUN; ...
This paper addresses the difficult problem of segmenting objects in a scene and simultaneously estimating their material class. Focusing on the case where, individually, no dataset can achieve such a task, multiple sensor datasets are considered, including some images for retrieving the spatial informat...
