Get new point coordinate by current Point coordinate, angle and distance

mohameantar — Tue, 20 Jul 2021 15:47:43 GMT

Hello all,

i want to create new point to be away by specific angle and distance from existing point .

i checked geometryEngine.offset but its working only for polyline or polygon not working for points also i need to control the angle so i create the new point up or down not only right and left.

Thank you all

I have some code that uses latitude and longitude as input values to calculate a second point based on bearing and distance. Haven't used this in quite a while. I'm not sure how much efficiency you need, you would have handle any additional coordinate conversions:

You can also try the pointFromDistance() method: Geodetically computes the location at a defined distance and direction from a known location.

Hi sir, we are using the same code as given but getting the point at a wrong distance, kindly help us how to get the new point at given distance.

For lat- lattittue

log- logitude

radius- distance we are passing(line distance)

bearing- angle

if we enter 200 mt distance, the line length will be 652 mt. How to get the new point at the exact line distance, which we are providing. The screen shot provided for reference.

As @JohnGrayson suggested below, try using the JS APIs geodesicUtils.pointDistance(): https://developers.arcgis.com/javascript/latest/api-reference/esri-geometry-support-geodesicUtils.html#pointFromDistance

Hi @JohnGrayson @AndyGup,

it's been a while since the pointFromDistance() hint, and the geodesicUtils have been deprecated in JSSDK v 4.33, and I can't seem to find an operator that solves this very problem. Am I missing something?

Thanks
Nik

@NiklasKöhn thanks for the feedback. Correct, there's currently no replacement for pointFromDistance(). We are looking into options for that.
