Quick Start
Click
in the QGIS Tool Bar or via to start the EO Time Series Viewer
Click
to load an exemplary time series of Landsat and RapidEye observations.Open the sensor panel
and change the sensor namesDefault
Changed

The change of sensor names becomes visible in other other parts of the GUI as well, e.g. the list of time series source images.
Use the scroll band and the map tools
to change the temporal and spatial subset shown from the time series.
Open the Mapping panel, change the map view name from Map View 1 to True Color and set the multiband color render band selection to RGB = 3-2-1 for both, Landsat and RapidEye images (right-click on layer,
).
Now we like to optimize the color stretch. Choose a -clouded Landsat observation like 2014-06-24 and use the map context menu (right-mouse-click) to click on
. Repeat with Linear and Gaussian stretch as well as for RapidEye images to see how this changes the band-specific min/max values in the Map View settings.Click
to create a second map view, respectively row of map images. Call it
Short-Wave IR
and the the multiband color render bands to Landsat RGB = 4-5-3 and RapidEye RGB = 5-4-3Expand the Map Properties combobox (in the Mapping panel), increase the map size to 300x300 pixel and press Apply.
Bring the Temporal Profile panel
and the 2D page to the front. Clickand select a map location to visualize the temporal profile for. Each selected map location will be listed in the panels
Coordinate page.
Go back to the 2D plot page and add a second profile with RapidEye data as Sensor source. Change the expression field to show the Normalized Difference Vegetation Index (NDVI) for both sensors:
Sensor
Expression NDVI
Landsat
(b4-b3)/(b4+b3)
RapidEye
(b5-b3)/(b5+b3)
