The SQL procedure allows the programmer to create a table(s), essentially a SAS dataset. Within a single SQL procedure, you have the ability to select specific rows by using a Where statement and even to sort your data by using an Order by statement. Merging multiple datasets using SQL is...
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...
