Pan
Click the Pan button, or select the Pan item from the drop-down button menu. The operation status in the current map changes to panning status, and the mouse cursor in the current map changes to
.
Additionally, pressing the A key on the keyboard or holding the middle mouse button can also switch the current map to the operation status of panning to browse the map.
- In the current map, hold down the left mouse button and drag; the map will pan in the direction of the drag. Release the left mouse button to stop panning, at which point the map refreshes.
- During panning while holding down the left mouse button, the map does not refresh in real-time, so blank areas may appear in the map. Only after releasing the left mouse button to stop panning will the map refresh.
- If real-time refresh is needed during map panning, use the Real-time Pan function.
Refresh the walkthrough
- Click the Pan drop-down button, select the Refresh Pan item from the pop-up menu. The operation status in the current map changes to refresh panning status, and the mouse cursor in the current map changes to
. - In the current map, hold down the left mouse button and drag; the map will pan in the direction of the drag. Release the left mouse button to stop panning. During panning, the map refreshes, making the panning process smooth.
Global Pan
Global pan refers to seamless panning across the Eastern and Western Hemispheres when browsing the world map, achieving the same experience as browsing the map on a sphere while on a plane. After enabling global pan, the start and end longitude of the displayed world map bounds are not limited to the -180 to +180 longitude range; they change as the mouse pans.
This function is mainly used in special scenarios that require crossing the Eastern and Western Hemispheres, such as drawing global navigation or aviation routes and measuring distances across hemispheres. Click the Pan drop-down button in the Browse group of the Maps tab, and select the Global Pan option to enable this function.
Global pan has certain requirements for the map's reference coordinate system. Currently, the coordinate systems supported for global pan are: WGS 1984 in the geographic coordinate system and World Mercator in the projected coordinate system.
