ArcGIS supports LAS datasets for lidar. There is a growing volume of gpr data for underground/subsurface imaging that should be supported at some level in ArcGIS, including the Image Extension for Server. There are parallels in supporting seismic data for geophysical exploration work. GPR and seismic data are multidimensional in nature and complex. The ArcGIS platform would be a nice fit for display and basic analysis and processing.
