Hand-held distance measuring device with angle calculation unit

The hand-held distance-measuring device (1) has a housing (4) and a distance-measuring unit, particularly a laser distance meter (20), for measuring distances to spatial points along an emission direction (9) in a space. An angle-determining unit (33) is provided for determining an angle of rotation between the housing and a referencing support (3). The housing and the referencing support are coordinated with each other such that a passive position is assumed by the referencing support, in which the referencing support is inserted into a recess (28) of the housing. Independent claims are included for the following: (1) a method for determining geometric data in the space by a hand-held distance-measuring device; and (2) a computer program product for executing the method.
