Abstract. The survey and representation of river landscapes require complex operations related to the habitat identifying these environments that show heterogeneous connotations in which the anthropogenic contaminations, alternating with the peripheral areas, industrial or abandoned, are united in a territory with hybrid characteristics.
In this regard it is proposed as a case study the experimentation carried out on the Pescara river basin that specifically compares two low cost detection systems comparing the results obtained to carry out environmental readings and 3D reconstructions of the territory.
The operations of analysis and data acquisition include integrated procedures used with the aim of obtaining high-density 3D reconstructions of details applied on the river portions of Pescara-Aterno. Starting from the delta towards the inside, identification samples were analyzed to focus attention on the different criticalities. Integrated methodologies were employed involving the experimental use of specific software to obtain depth maps and territorial models compatible with real ones, crossing free open shared data obtained from the Google Earth Pro, photogrammetric reconstructions and information provided on site by RPAS instruments (Remoted Piloted Air System) that use the image based methodologies to carry out an in-depth scan of the territory.
