Product View

If you create a new, open or import an existing data product, the Sentinel Toolbox will put it into it's open product list. The product list is a tree view with up to four root nodes for each open product:

• Bands - contains all measured spectral/geophysical and quality raster datasets of a product (mandatory)
• Vector data - contains all geometries of a product: pins, ground control points (GCPs), lines, polylines, rectangles, ellipses, and polygons (optional)
• Tie-point grids - contains all tie-point grid raster datasets (optional)
• Flag Codings - contains flag coding metadata for quality flags datasets (optional)
• Index Codings - contains index coding metadata for classification bands (optional)
• Metadata - contains additional metadata (optional)

You can quickly open an Image View for a band or tie-point grid by double-clicking on an item of the expanded product root nodes. Accordingly a metadata view is opened if you click an item the flag coding or metadata nodes. Please also refer to the Navigation Window and the the Zoom and Panner tools.

The information concerning each pixel can be analysed interactively in the pixel information view.

Pixel Info View

If you click on the tab 'Pixel View' (by default on the left side of the Toolbox), pixel information will be displayed while you move the mouse over the band image view.

You can un-dock each frame using the floating-button (), and dock it back to the Pixel View by using the close-button () in the header bar. If it is already docked and the close-button is used the corresponding frame is hidden. In floating mode the docking-button () lets the window dock to the main frame as any other tool view.

The buttons at the bottom of the Pixel View switch the visibility state of the corresponding frame, regardless if its currently floating or docked.

The informations displayed belong to the current image pixel beneath the mouse pointer:

• Geo-location:
  Displays the image position, the geographic-location and also the map co-ordinates if the current product is map-projected.
• Tie Point Grids:
  Shows the values of the tie-point grids.
• Time Info:
  The time information associated with the current line.
• Bands:
  The value of the pixel beneath the mouse pointer.
• Flags:
  Displayes the state of the flags at the current pixel.

If a pin is selected in the current image view you can select Snap to selected pin in order to "freeze" the pixel info to the position of the currently selected pin.

Note: In the Options Dialog you can deselect the option that only pixel values of displayed bands are shown.
