Use the Manage Tie Points feature when you need to manually add or edit tie points to improve geometric accuracy.
For operations related to adding, modifying, and deleting points, please refer to Edit Points. This article focuses on the filtering, searching, and sorting functions for tie points.
This feature is only available when a tie point dataset exists in the current workflow.
SuperMap iDesktopX11i(2023) version and later support this feature.
Function Entry

Filter
Click the Filter button on the toolbar to access the following three filtering methods for filtering the generated tie point records in the attribute table.
- Current Map Extent：The attribute table only displays the attributes of tie points currently visible in the map.
- Match Image：Select one or more images, and the attribute table will display the attributes of tie points associated with the specified image(s).
- SQL Expressions:Select this option to set an SQL filter expression by clicking the button on the right, or directly enter the expression in the input box. The attribute table will display the control point attributes that meet the expression criteria.
Search
The toolbar includes a search box that supports entering keywords for quick retrieval, helping you quickly locate the desired content and improve query efficiency.
