-The **_Orthorectification 🡪 Orthorectification 🡪 Verify Reference Points_** menu allows you to check the quality of the match between terrain and image coordinates of the GRPs. The orthorectification matrix (see [Principles of Orthorectification](#approfondissements)) is calculated, and the terrain position (X; Y; Z) of the reference points is determined from their image coordinates (I and J).

 Then, the real terrain coordinates are compared with the calculated terrain coordinates. The distance between these real and calculated coordinates, called **_Offsets_**, is shown in a table and as a graph.

 - Define the study area with a rectangle, specifying the corner positions in the real-world coordinates (**_Xmin, Xmax, Ymin, Ymax_**). This frame limits orthorectification to the area of interest, thus reducing computation time.
 - **_Resolution_**, in meters per pixel, represents the size of one pixel in the orthorectified image. Adjust the resolution to keep tracer details visible in the orthoimage without producing excessively large orthoimages (the orthoimage should be about the same size as the raw image). The button ![image53](uploads/67c708dadea4320b35173c0f5155cc72/image53.png) automatically fills in the fields **_Xmin, Xmax, Ymin, Ymax, and Resolution._**
