1. A method for reducing geographic information services (GIS) data collection errors comprising:
- providing a mobile GIS data collection device including;
a global positioning system or global navigational satellite system (GPS/GNSS) receiver, a laser rangefinder having an aiming direction, a digital compass, pitch and roll sensors, a video camera, a video display showing video images obtained by the camera, and a processor;
the GPS/GNSS receiver estimating the position of the GIS data collection device;
the processor estimating the position of a target object with respect to the GIS data collection device based on data obtained by the laser rangefinder and the pitch and roll sensors;
the processor drawing on the video display an aiming symbol corresponding to the aiming direction;
the processor drawing on the video display an augmented reality target marker to mark a measured target object, the target marker appearing to remain fixed to the target object even as the field of view of the camera changes; and
,the processor drawing on the video display an augmented reality accuracy marker that shows estimated accuracy of a position measurement of the measured target object.
