A pin is a marker for a certain geographical position within a geo-referenced image. The properties of a pin are
Pins are displayed as symbols at their geographical positions in image views associated
with the current product. Pins are stored in the current product and available again if the
product is re-opened.
In VISAT, pins can be used to "freeze" the
pixel info view and the
spectrum view to the selected pin in order to display
the values of the pixel associated with the selected pin.
New pins can be created with the pin tool and removed using the
delete pin command in the Edit Menu.
It is also possible to create and remove pins by using the pin manager.
The pin tool is used to create a new pin but and also to select an existing pin. If the pin tool is active, a click into an image view creates a new pin at the clicked pixel position. The edit pin dialog appears then and the new pin's properties can be edited. If you click on an existing pin is becomes the selected pin. If you double-click on an existing pin the edit pin dialog appears and lets you the edit the properties of the selected pin.
The pin manager is used to display all pins stored in the current product within a table and provides some pin related operations.
If you click on a pin within the table it becomes the selected pin. Double-clicking on pin in the table opens the edit pin dialog.
