convert points to polyline to polygon to calculate area

PeterBennett1

Hello All, good morning!

I have a set of points (lat and lon) that shows a vehicle route/path, I want to get the area covered by that vehicle.

What would be the best approach to get this done?

Cycle through each point to build a polygon, joining first and last point?

How do I build a polygon that has all points as a perimeter?

Thank you in advance

Best Regards

@Dan not if you use the geodesic area calculations provided by the geometry engine 😉 In that case it's actually better - I'm a big believer in never doing area calculations in a projection but keeping it all in spherical coordinates and using ellipsoidal calculations.

But to answer the question: You can create a polygon from a set of points, and you can get that set of points from the polyline path. Ex:

    var myPolygon = new Polygon(myPolyline.Parts[0], myPolyline.SpatialReference);

Alternatively use the PolygonBuilder to add vertices one by one in a loop, and call ToGeometry() when you're done.
