A new approach for subsurface space mapping of urban area using RS and GIS
The high resolution images are taken as the information source to attempt the inversion detection of the spatial resources use in the investigation area.Through visual interpretation of geometry shape of the remote sensing data,inquiry of historical archives of city planning department and in situ investigation,confirmation,analysis of each region,the distinction pattern of relations between the structure height,the structure style and the depth of the foundation ditch is established.Afterwards,the spatial distribution of the construction in Hangzhou urban area is interpreted.On the basis of the foundation pattern used by the construction and correlating distinction pattern,the used subsurface space structure is determined with the help of GIS spatial statistical analysis technology.The result can provide macroscopic information for investigating usable subsurface space resources.It also can assist the engineering geology and hydrology geology data to establish full and accurate analysis of subsurface space use,which provide the policy-making suggestion for the cultural relics preservation and the important project using subsurface space such as the subway construction.
