Polish term or phrase: Obiekt kontrolny sytuacyjny
Obiekt kontrolny sytuacyjny stanowią kalenice dwóch dachów o prostej konstrukcji (najczęściej dwuspadowe), które ułożone są prostopadle (lub prawie prostopadle) w stosunku do siebie.
W przypadku gdy w danym obszarze analizowanego Bloku LIDAR nie występują budynki, do analizy sytuacyjnej wykorzystane zostaną obrazy intensywności, na podstawie których jednoznacznie zidentyfikowane zostaną szczegóły terenowe.

w kontraście do:

Obiekt kontrolny wysokościowy stanowi siatka punktów - co najmniej 3x3 punktów - zlokalizowana na równych płaskich powierzchniach.

To differentiate from vertical control reference points, one has more precisely,
ground control reference points
Ground control reference points can be used to determine the absolute phase ambiguity

The geographical information system database (ArcView
GIS) was used to perform the calibration of coordinates
of the image data. After the completion of coordinate
the calibration via ten ground control reference points
(GCP; Table 1 and Fig. 1), a overlay analysis was carried
out to evaluate the RMS errors of image data (Table 2).

point-based reference control from lidar data for subsequent use in aerial triangulation. Kwak et al., 2006 and Mitishita et al., 2008, for example, used centroids of rectangular building roofs as a single control point in the aerial triangulation process

The presented work covers methods for the detection of remaining discrepancies in overlapping LiDAR strips with main focus on the development of a new precise 3D measurement technique based on intersecting roof ridge lines and roof planes which are automatically reconstructed from the LiDAR point clouds in overlapping strips.

For the generation of 2D and 3D control points, several roof
ridge lines
were determined photogrammetrically by measuring
sample roof ridge points in digitized aerial images with nearly
the same acquisition date as the LiDAR data.

horizontal reference point


Explanation:
Myślę że choć odpowiedź Franka idzie dobrym tropem, z dalszego opisu wynika jednoznacznie, że chodzi o punkt odniesienia w płaszczyźnie poziomej,
w przeciwieństwie do: "Obiekt kontrolny wysokościowy" - stąd moja alternatywa
