- Description of processed data sources
-
Description of processed data sources :
Data were provided by ARPA-Environmental Engineering who has been active in monitoring on behalf of the Emilia-Romagna. The measurements were conducted by Geosystems Ltd of Parma, who took over the whole coast region, to a depth of about 8-9 m along 251 transects perpendicular to the shoreline spaced about 500 meters and a series of transverse lines of relief , for a total of 200 km. Data were collected with multiple echosounders:
1. Sinlge beam echo sounder (200 KHz) for the shallow water areas up to 1.5m
2. multi beam echosounder (455 Khz and max swath angle of 120°) for water depth up to 10m.
- Description of data processing
-
Description of data processing :
The bathymetric soundings were distributed not homogenously along he major transect and the DTM was derived both from soundings and countours manually drawn. Multi beam soundings were filtered (low filter)to remove spikes particularly those present at the edges of the tracklines. A first processing produced a DTM with a resolution of 10m, and contour lines every 0.25m Contours generated automatically were subjected subsequently to a manual correction, taking into account the distribution of data and the presence of natural and man-made structures deduced from the photo-interpretation of the flight Costa 2005. The final product is a series of contour lines of both the emerged part and the submerged part with equidistance 0.25 but starting from +3.5 to -10 m
