It is possible to assign a Site Localization to a new or existing “Point CRS” collection and get the local equivalent coordinate system for every measured or imported point. Coordinates will be computed automatically according to the site localization selected.

Assign Site Localization to a New Point Collection

Measure or import new points using a site localization file. All the points in the new collection will be site localized in the process.

1. From the Point Management dialog, create a new point collection by tapping the button.
   

   

   PIX4Dcatch Create Point Collection dialog.

   • Name the Point Collection.

2. Choose a Site Localization collection.

   

   PIX4Dcatch Assign Site Localization dialog.

   • Select the appropriate Site Localization collection.
3. The selected site localization will appear near the top of the Point Collection with the Coordinate Reference System selected for the global points.

Assign Site localization to an Existing Point Collection

It is easy to assign a site localization to an existing Point Collection.

1. From an existing Point Collection, tap the menu icon in the upper right of the screen.

   

   PIX4Dcatch Point Collection dialog.

   • Select Assign Site Localization.
     • Select the appropriate Site Localization.
2. Tap the global point to view the local transformation. Selecting the Local Position tab will display the local coordinates computed automatically according to the site localization selected.

Remove Site Localization

It is possible to remove Site Localization previously assigned to a Point Collection.

1. From a Site Localized Point Collection, tap the menu iconin the upper right of the screen.

   

   PIX4Dcatch Point Collection dialog.

   • Select Remove site localization.
     • Confirm by tapping REMOVE in the warning dialog.
