Abstract: A mobile terminal device has a display for indicating guidance of a route retrieved by a route retriever and a GPS receiver for detecting the present location. A route retrieval server has a database for storing the present location of each bus running on bus lines and an alternative route guider for evaluating alternative bus route to provide guidance. When the guided route includes a walking route, the route retriever references the database based on the present location of the mobile terminal device to identify an alternative route that includes a bus. The alternative route guider compares the alternative route and guided route. When the alternative route is more favorable than the guided route, the alternative route guider sends alternative route information indicating presence of the alternative route to the mobile terminal device, displays the guided route on a display, and indicates the presence of the alternative route.

Abstract: A mobile terminal device has a display means for indicating a guidance of a route retrieved by a route retrieval means and a GPS receiver means for detecting the present location. A route retrieval server has an operation service information database for collecting and storing the present location of each bus running on bus lines and an alternative route guiding means for evaluating alternative bus route to provide a guidance. When the guided route includes a walking route block, the route retrieving means makes reference to the operation service information database in accordance with the present location of the mobile terminal device to identify bus services which a user of the mobile terminal device can use for retrieving a route alternative to the walking route block, while the alternative route guiding means compares the route data between the alternative route and guided route.

Abstract: To provide measurement data on a real time basis from a laser measurement device mounted on an air vehicle to a ground station. The laser measurement unit sequentially outputs laser measurement data during a measurement period in which the air vehicle flies along a straight line flight fairway (32). The transmission unit desirably compresses the laser measurement data when the laser measurement data is accumulated to a file size while the air vehicle flies along straight line flight fairway (32), and transmits the laser measurement data to the ground station. The transmission units does not transmit the flight state data obtained by the GPS/IMU to the ground station on the straight line flight fairway (32), but transmits during a measurement suspended period in which the air vehicle flies along a turn fairway (34).
