By default, the table in the Raw Image Summary Table window is sorted alphabetically in ascending order by image ID. You can sort the table by column heading to make the contents easier to view and analyze. For example, to quickly compare the number of ground control points (GCPs) per image in your project, you can sort the table by GCPs.
To sort by column heading
- Click the column heading by which you want to sort the information.
- Click the column heading again to switch between descending and ascending order, and vice versa.
A
beside the column heading indicates that the data is sorted alphabetically (for text data) or numerically (for numeric data) in ascending order. A 
indicates that the data is sorted in descending order.
