I am trying to delineate agriculture tile drainage in Midwest.I wonder if anyone has come across with GIS and sub-surface remote sensing techniques to detect tiles/objects buried in shallow depth of soil ?Does anyone have any suggestions as to what type of remote sensing can be used to detect subsurface features?I can think of GPR(ground penetrating radar). Any other suggestions would be appreciated.
Thanks in advance !
