TMP302: Measuring temperature of voltage plane.

Part Number: TMP302

I want to measure the temperature of a voltage plane. This voltage plane is my heat source as indicated in Figure 14 of TMP302 datasheet. Figure 14 indicates a "Ground Plane for Thermal Coupling to Heat Source". Is this a signal Ground Plane or a Thermal Ground? If so it would obviously short circuit my voltage. Please advise.
