Click Yes to confirm you want to remove the selected control.On the Home tab, click the Control drop-down list.Use the Select tool to select the control points you want to remove.To set the control type using the control tool, complete the following steps: There are two ways to set your control type. The difference between the initial and the computed positions of the checkpoints is displayed in the Processing Report, and it gives an estimation of the absolute accuracy of the model in the region. This way, the relative accuracy in the area of the checkpoints may improve. The image links for the checkpoints are used to estimate the model's 3D position as well as potential errors in the placement of the check points. GCPs improve the relative and the absolute accuracyĬheckpoints (CPs) are used to assess the absolute accuracy of the model. Some of the GCPs can be used as checkpoints to assess the accuracy Project than necessary to accurately scale, rotate, and locate, Ground control points (GCPs) are used to georeference the model. Control typeĭrone2Map allows you to set your control as a Ground Control Point or Check Point. For more accurate adjustments, use a local DEM and ensure it is the top layer in the Elevation Surfaces section when adding ground control points from the map. If there is an offset between output products and the elevation surface, it is likely that the WorldElevation3D/Terrain3D layer was used for adjustment. By default, ground control points added from the map will take the z-values from the topmost elevation surface in the Elevation Surfaces section of the Contents pane.
