Restrict camera view and bounds

Select platform: Android iOS JavaScript

It may be desirable for you to control the camera's pan, maximum altitude, or to create latitude and longitude boundaries restricting a user's movement in a given map. You can do this using camera restrictions.

The following example shows a map with location boundaries set to limit the camera's movement:

Restrict map bounds

You can restrict the geographical boundaries of the camera by setting the bounds option.

The following code sample demonstrates restricting the map bounds:

TypeScript

asyncfunctioninit():Promise<void>{
awaitgoogle.maps.importLibrary('maps3d');
constmap3DElement=document.querySelector('gmp-map-3d')!;
// Restrict the position of the camera to the specified bounds.
map3DElement.bounds={
south:-48.3,
west:163.56,
north:-32.86,
east:-180,
};
}
voidinit();index.ts

JavaScript

asyncfunctioninit(){
awaitgoogle.maps.importLibrary('maps3d');
constmap3DElement=document.querySelector('gmp-map-3d');
// Restrict the position of the camera to the specified bounds.
map3DElement.bounds={
south:-48.3,
west:163.56,
north:-32.86,
east:-180,
};
}
voidinit();index.js

Restrict the camera

You can restrict the movement of the camera by setting any of the following options:

maxAltitude
minAltitude
maxHeading
minHeading
maxTilt
minTilt

The following code sample demonstrates restricting the camera:

// Restrict the movement of the camera.
map3DElement.maxAltitude=1000;
map3DElement.minAltitude=500;
map3DElement.maxTilt=55;
map3DElement.minTilt=35;

Restrict map and camera bounds

You can simultaneously restrict both map and camera bounds. The following code sample demonstrates restricting both map and camera boundaries:

// Restrict the movement of the camera.
map3DElement.maxAltitude=1000;
map3DElement.minAltitude=500;
map3DElement.maxTilt=55;
map3DElement.minTilt=35;
// Restrict the position of the camera to the specified bounds.
map3DElement.bounds={
north:20.93,
west:-156.38,
south:20.90,
east:-156.31,
};

Control gesture handling

When a user scrolls a page containing a map, the scrolling action can inadvertently cause the map to zoom. You can control this behavior by setting the gestureHandling map option.

gestureHandling: `cooperative`

"Cooperative" gesture handling allows the user to scroll the page without impacting the map's zoom or pan. To zoom, users can use the controls, two-finger gestures (for touchscreen devices), or by holding CMD/CTRL while scrolling.

The following code demonstrates setting gesture handling to "cooperative":

<gmp-map-3d
 id="gmp-map-3d"
 center="20.92,-156.36,500"
 tilt="67.5"
 mode="hybrid"
 gesture-handling="cooperative">
</gmp-map-3d>

gestureHandling: `greedy`

"Greedy" gesture handling reacts to all scroll events and touch gestures.

gestureHandling: `auto`

"Auto" gesture handling changes the behavior of the map depending on whether or not the map is contained in an <iframe>, and whether the page is scrollable.

If the map is within an <iframe>, gesture handling will be "cooperative".
If the map isn't within an <iframe>, gesture handling will be "greedy".
