The results of flight simulation using DTM showed the obvious difference in the logging area among landing places. It was also made clear that the optimal location of a landing place or heli-port in aerial logging should be satisfied with the following conditions, 1) it faces to wide open basin with few obstacles to helicoper flying, which makes helicopter easy to take off and landing, 2) it places at the nearly center of the logging sites to decrease average flying time, 3) there is few difference in the altitude between loading sites and a landing place.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"55332","nameIdentifierScheme":"WEKO"}],"names":[{"name":"ITO,
