The FP7 project HELCATS (Heliospheric Heliospheric Cataloguing, Analysis and Techniques Service) is designed to add value to the STEREO Heliospheric Imaging observations by: cataloguing phenomena such as coronal mass ejections and stream interaction regions; producing derived ‘metadata’ products; applying computer modeling techniques; and finally by comparing them with other datasets.

A specific goal of HELCATS is to assess the potential for combining white-light imaging of the inner heliosphere with ground- and space-based radio data, in particular Interplanetary Scintillation (IPS) and Type II radio bursts. In this contribution we present initial results from this on-going subproject examining the statistical association of CMEs in the HELCATS catalogue with Type II radio emission. We illustrate the analysis with case studies examining specific events. The value of the radio observations in constraining CME kinematics is discussed.
