Can I eliminate the redundant points after running GeometryService.simplify?

StephenLam — Mon, 04 Aug 2014 10:26:45 GMT

I am trying to implement a buffer zone search, after I read this, using GeometryService.simplify

gsvc.simplify([evt.geometry], function (geometries) {

params.geometries = geometries;

gsvc.buffer(params, showBuffer);

});

I successfully get a buffered geometry, say rectangle, however the returned geometry has a lot of vertex at the corners, so it is inconvenient to modify the shape...Is it possible to just get a "4 points rectangle" with buffered size? Thanks.

Stephen,

Simplify takes care of counter clockwise polygon orientation and polygon self-intersecting, etc. I think what you want is the GeometryService.Generalize

Hi Stephen,

1. One option is to get envelope of the buffer geometry, this will always be a 4 point rectangle.

2. If you are looking for a minimum bounding rectangle then you may want to create a geoprocessing service using minimum bounding geometry tool. Refer below links on how to go about it.
