Recently, TAMA300 and other ground-based interferometric gravitational wave detectors made a scientific observation. These have enough capability to detect gravitational wave events in our galaxy. We show some advantages of simultaneous observation and its coincidence analysis using these detectors from the point of view of the event search. One of the important advantages is that a detector network will make it possible to determine the gravitational wave source direction. We calculated the angular resolution of source direction with the assumption of recently operating detectors' placements. The angular resolution deltatheta is estimated as typically 2.47° for the whole-sky average with 0.5 ms accuracy of gravitational wave arrival time DeltaT. The dependence is estimated as deltatheta [deg] = 3.5 × surd(DeltaT [ms]). We also estimate deltatheta for neutron star binary or MACHO events in our galaxy as deltatheta [deg] = 4.4 × surd(DeltaT [ms]).
