# Selection Methods

There are two ways to select data:

1. Shift + drag a rectangle to define an area of interest.
2. Click the “Selection Mode” button and draw without holding Shift.

Tips and constraints:

* Selection is enabled from zoom level 10; selection accuracy improves at zoom ≥ 13.
* Hovering items highlights them on the map; selected files appear in the sidebar.
* You can group and manage selections by mission (expand/collapse, select all).

Also available: “Click-to-Jakartowns” mode opens the 3D viewer at a clicked map location—useful to preview areas before selecting.
