Mapping and localization using surface features is prone to failure due to environment changes such as inclement weather. Recently, Localizing Ground Penetrating Radar (LGPR) has been proposed as an alternative means of localizing using underground features that are stable over time and less affected by surface conditions. However, due to the lack of commercially available LGPR sensors, the wider research community has been largely unable to replicate this work or build new and innovative solutions. We present GROUNDED an open dataset of LGPR scans collected in a variety of environments and weather conditions. By labeling this data with ground truth localization from an RTK-GPS / Inertial Navigation System, and carefully calibrating and time synchronizing the radar scans with ground truth positions, camera imagery, and Lidar data, we enable researchers to build novel localization solutions that are resilient to changing surface conditions. We include 108 individual runs totalling 450 km of driving with LGPR, GPS, Odometry, Camera, and Lidar measurements. We also present two new evaluation benchmarks for 1) Localizing in Weather and 2) Multi-lane Mapping, to enable comparisons of future work supported by the dataset. The dataset can be accessed at
