You may wish to use a swing GlassPane and draw a second map consisting of
just the single feature, or better yet draw the feature into a buffered
image once, and then draw that buffered image in different locations as the
user drags. When they release you can update the data, and refresh the map.

What NetFlow Analyzer can do for you? Monitors network bandwidth and traffic
patterns at an interface-level. Reveals which users, apps, and protocols are
consuming the most bandwidth. Provides multi-vendor support for NetFlow,
J-Flow, sFlow and other flows. Make informed decisions using capacity
planning reports. https://ad.doubleclick.net/ddm/clk/305295220;132659582;e
