Provide Generalize functionality

[josephyannkaewang]

To speed up geo query, it will be nice if there is a way to check if the shape is simple and provide a way to convert a shape to its simplified version.

Are you using Hive or custom Java MapReduce?
The Geometry API has Simplify methods.

I've tried

OGCGeometry ogcGeom = OGCGeometry.fromGeoJson(json);
if (ogcGeom != null) {
Geometry geometry = ogcGeom.getEsriGeometry();
SpatialReference spatialReference = ogcGeom.getEsriSpatialReference();
Geometry simpleGeometry = GeometryEngine.simplify(geometry,
spatialReference);
if (simpleGeometry != null && spatialReference != null) {
OGCGeometry ogcGeom2 =
OGCGeometry.createFromEsriGeometry(simpleGeometry, spatialReference);
return GeometryUtils.geometryToEsriShapeBytesWritable(ogcGeom2);
}
}

GeometryEngine.simplify doesn't seem to take a parameter for
specifying how much to simplify it by.

Oh, the other meaning of Simplify, not in the sense of ST-IsSimple.
Better to move the issue to Geometry API.

[randallwhitman]

In the geometry API, the requested operation is called Generalize.
