iGPR-Core is a web application that allows registered uses to specify core data, including PDF log files, so that iGPR (shown below) can make use of them. A core defined within iGPR-Core will appear in the Google Map view and also displayed along with the GPR traces in the Pavement Structure tab of iGPR.

You must first register (see sidebar on the left) before you can add cores to iGPR-Core. Once you have been approved you may add cores and they will be viewable in iGPR within a short time.
