Zoom Out from a Queried Feature

JeffHanson2 — Wed, 10 Jan 2024 12:50:01 GMT

I have a simple problem I can't seem to solve. I query a feature and zoom to it:

feaFarms.queryFeatures(query).then(function(results){

const features = results.features;

//view.goTo(features[0].geometry, 1000);

var geometry = features[0].geometry;

view.goTo(features[0].geometry);

After I "goTo" the queried feature geometry I want to zoom out a percentage so I can show some of the area surrounding the feature of interest. I've tried getting and setting the scale but that doesn't work real well.

Hi @JeffHanson2, thanks for posting your question here. You can clone the geometry of the extent, and then expand by a value greater than 1 to zoom out a bit, like this:

feaFarms.queryFeatures(query).then(function(results){

const features = results.features;

var geometry = features[0].geometry.extent.clone().expand(1.5);

view.goTo(geometry);

}

I also got this code to work:

var geometry = features[0].geometry;

var buffer = geometryEngine.buffer(geometry, 10, 'feet');

view.extent = buffer.extent.expand(2);
