a) Tracking the aircraft using the Annotation Tool (LEOWorks 3)
 
Introduce the planned flight trajectory onto the satellite image using the Annotation Tool. Carefully draw a polyline starting from Mendoza down to Malargue, across the Andes to Curicó, and then northwards to Santiago.

Annotate the turning points with their appropriate names. Mark the exact impact position of the aircraft. Place a small circle on this location. Afterwards, trace a likely track ending where the aircraft’s fuselage was found.

Save your annotated image as MERIS_FR_20070318_321_annotated.tif or MERIS_FR_20070318_432_annotated.tif, depending on which file you used.
 
 
b) Tracking the aircraft using the GIS Tool
 
You can also track the aircraft using the GIS Tool. Make a layer “Flight Track”, select Polyline and carefully draw the line between the 4 positions (Mendoza, Malargue, Curio and Santiago). Make another theme layer and name it “Location of Accident”. Select Point and click on the exact position of the location of the crashed aircraft.

When generating/saving the layers, make sure you save them in the same directory where you are working.
