Spatial analysis of GPR data (original) (raw)

The article contains information about the possibilities of using spatial analysis by means of GIS applications to evaluate the results of a GPR survey. Separate GPR profiles contain useful information about the internal structure and condition of pavement structures in certain sections of the road. At the same time, in order to effectively search for weakened zones of road structures and explain their causes, it is also necessary to analyze the relief, situation, and hydrogeological features of the area. Spatial analysis allows you to combine different models of the existing reality in one software window. For example, to see the connection between the places of subsidence of pavement layers, the formation of voids or decompression in the layers of the base of the pavement with the location of underground structures (utilities, underpasses, etc.). The article contains a description of the methodology of spatial analysis and the results obtained on the example of a GPR survey of roads in Moscow.
