Measuring system and method for marking a known target point in a coordinate system

A surveying system for marking a target that is known in a coordinate system, comprising:

• a mobile marking unit configured to precisely determine a marking unit position using a customizable reflector and/or a GNSS antenna;
• a geodetic surveying appliance for determining the position of the marking unit, the geodetic surveying appliance having access to data, stored in a database, representing a target position of the target, and including:
• a targeting unit that defines a targeting direction;
• an angle measuring functionality;
• a camera for capturing a camera image;
• an output unit on which the camera image, together with the target position and/or the marking unit position, can be presented;
• and
• a control and processing unit;
• and
• presentation functionality that, under the control of the control and processing unit, enables display on the output unit of a spatial discrepancy between the marking unit position and the target position, the spatial discrepancy being displayed:
• in a first direction using a first discrepancy indicator that indicates an interval from the target position to a plane defined by the surveying appliance and the marking unit;
• and
• in a second direction using a second discrepancy indicator that indicates an interval from the target position to a normal to the plane, which normal is stipulated by the marking unit position;
• wherein the spatial discrepancy is presented independently in the first direction and in the second direction.

A geodetic surveying appliance that has access to data, stored in a database, representing a target position of a target, the geodetic surveying appliance comprising:

• a targeting unit that defines a targeting direction;
• angle measuring functionality for capturing the orientation of the targeting unit;
• a camera for capturing a camera image;
• an output unit on which the camera image can be presented;
• a control and processing unit;
• and
• presentation functionality that, under the control of the control and processing unit, enables display on the output unit of a spatial discrepancy between the marking unit position and the target position, the spatial discrepancy being displayed:
• in a first direction using a first discrepancy indicator that indicates an interval from the target position to a plane defined by the surveying appliance and the marking unit;
• and
• in a second direction using a second discrepancy indicator that indicates an interval from the target position to a normal to the plane, which normal is stipulated by the marking unit position;
• wherein the spatial discrepancy is presented independently in the first direction and in the second direction.

A surveying system for marking a target that is known in a coordinate system, comprising:

• a mobile marking unit configured to precisely determine a marking unit position using a customizable reflector and/or a GNSS antenna;
• a geodetic surveying appliance for determining the position of the marking unit, the geodetic surveying appliance having access to data stored in a database representing a target position of the target and a map view of a terrain that has the target, the geodetic surveying appliance including:
• a targeting unit that defines a targeting direction;
• angle measuring functionality;
• a camera for capturing a camera image;
• an output unit on which the camera image and/or the map view can be presented;
• and
• a control and processing unit;
• and
• indicator functionality having an automatic changeover function that, when executed under the control of the control and processing unit:
• initiates display of the camera image and/or the map view on the output unit when a defined indicator criterion is met, the defined indicator criterion being a position ratio between the target position and the marking unit position;
• automatically initiates changeover between the camera image and the map view by taking account of a distance and/or angle threshold value, wherein the camera image and/or the map view are displayed together with the marking unit position and/or the target position.
