Each survey contains a number of items which are organized in different levels. The levels form a hierarchy as following:
This hierarchy is shown in a graphical way on the left part of the DET window. You can click on its nodes to expand or collapse the contents of each node.
The Item list Tree
Each node (BH,SPD or item) is labeled with the name of the respective object. You can also change the default appearance to include the code as well.
The tree is annotated with different colours and icons. You can see their meanings by clicking on the View -> Icon Legend... Menu.
Clicking on a node will change the contents of the right part DET window. The contents differ depending on the level of the selected node. All three upper levels (root, BHs,SPDs) show statistical information in tabular formats. You can see different kinds of information but you cannot change anything.
To enter observations you need to select an item. All items are in the last level of the tree. Upon clicking on an item, the right part of the window will present the observations table.
