Adventure continues What did we do? (briefly project topic) How
did we do? (methods / approaches) What did we do with?
(technologies) What are we doing? (current state) What will we do?
(future work)
Slide 4
Search & rescue teams Their performance is vital! They
need: time, point and direction to go. They need to be encouraged,
helped. FTL will help them.
Slide 5
3D map Paths on land Countless different paths Fastest path
Depends on vehicle & weather Paths for also air What did we
do?

Slide 11
How did we do? Algorithm Component Vector map of DTED Dijkstra
algorithm (modified for fastest path) Map Visualization Android
Interface
Slide 12
Digital terrain elevation data
Slide 13
Vector map (target area)
Slide 14
Vector map (fastest path)
Slide 15
Slide 16
Dijkstra algorithm (modified) finds shortest path Side view of
map Path length height finds fastest path Path time = Path length /
(velocity of vehicle depending on height) 1212 m 1235 m 30 m

Slide 28
What are we doing? Algorithm component is totally finished Map
visualization User Interface are partially finished. Touch movement
actions Integration completed }
Slide 29
What are we doing? We have contacted with AKUT at Isparta. They
have visited our stand at Sleyman Demirel University Project
Competition. We have exchanged ideas about usability of FTL.
Moreover, our project was awarded 2nd place in 55 different
projects.

What are we doing?
Slide 31
Slide 32
What will we do? Bugfixes Preventing memory overflow Proper
working of movement actions Bluetooth connection between tablet and
smart phone Texture mapping of satellite photos over 3D map
Improving performance of algorithms Enlarging map if Android allows
Path for helicopter
