Does anyone know how to change the geometry after receiving from Input
Change the geometry how?
At the 10.2.x product release you won't be able to do much with a Geometry event attribute. For example, you cannot reach into a Geometry to retrieve its coordinate values.
At the 10.3 product release there will be a new type of processor available to incorporate into your GeoEvent Services which will allow you to buffer a received Geometry ... for example.
Here's a link to a catalog of the product's available tutorials.
In 'Appendix A' of the tutorial there is a section Using a Field Calculator Processor to compute a Geometry which shows how to generate a String representation (as JSON) of a "geometry", incorporating coordinate values from a received event into a Field Calculator processor's expression. Any changes you want to make to an event's "geometry" might need to follow that pattern.
