DESCRIPTION:Inspection and maintenance of structures and infrastructures ar
 e\, nowadays\, hot topics. Extreme weather events and ageing stock\, mainl
 y\, deteriorate the network infrastructure. Their structural performance s
 hould be checked periodically\, but this is not always possible\, both bec
 ause of the difficulty to practically carry it out and because\, sometimes
 \, insufficient funds are allocated to infrastructure management. In most 
 of the western countries\, a highly percentage of bridges\, roads\, viaduc
 ts were built between the 1950s and the 1970s\, so the detection plays a f
 undamental role for their proper functioning. Traditionally\, instruments 
 such as levels and total stations have been used to perform high accuracy 
 Structural Health Monitoring (SHM). These can provide highly reliable real
 -time data on structural condition but\, both because of economic reasons 
 and of the difficult-to-access areas\, not all the structures and infrastr
 ucture can be monitored with traditional techniques. Remote sensing can pr
 ovide numerous advantages for structures and infrastructures monitoring\, 
 because the information can be extracted “from distance” with high rel
 iability and relatively low costs. A comprehensive review on the remote se
 nsing techniques used for structure and infrastructure monitoring is prese
 nted in this paper\, focusing the attention especially on satellite remote
  sensing and UAV photogrammetry techniques. Nowadays\, SAR (Synthetic Aper
 ture Radar) and optical images are widely used for the aforementioned purp
 ose. From one side\, the PSIn-SAR (Permanent Scatterer SAR Interferometry)
  has been exploited to extract information on ground and infrastructure mo
 vements\; on the other side\, optical images allowed to understand the cha
 nges occurred in areas of interest by performing a change detection analys
 is with different algorithms. UAV photogrammetry outputs have been used fo
 r more detailed surveys on specific structures or infrastructures\, both t
 o metrically model the objects and\, consequently\, to detect the degradat
 ion phenomena. The main results and consideration obtained by the state of
  art are discussed and compared and the main advantages and limitations ar
 e\, finally\, outlined in order to provide general achievements within thi
 s field.
