FLOOTSI GUI is the system responsible for pre and post processing of the data. It is a GIS system able to represent data in 2D and 3D.

FLOOTSI mainly works on a Digital Terrain Model (DTM). A DTM is a raster layer (Regular GRID) that contains in every GRID cell the georeferred height of the terrain in where the simulation will take place

Main features

FLOOTSI is a layered GIS system that can read most of the standard formats ion the market (vectorial, satellite and raster). Its main features are:

• Read and Write vectorials, satellite images and Rastes Layers.
• Open WMS Layers.
• Resample and SuperSampling Raster Layers.
• Expand, Export and Union Raster Layers.
• Import From XYZ GRID and STL Layers.
• Project and Reproject Layers.
• Edit Raster Layers.
• Copy Cell Values from Neighbor Cell.
• Smooth Raster Layers.
• Copy/Paste Raster to Raster.
• Create Vectorial Contour Curves from Raster.

The most important features of the pre-process are:

• Create raster Mask from DTM Raster to define the simulation area
• Create Friction Coefficient.
• Create Wall Boundary.
• Flux Boundary Conditions Tool.
• General Data Tool.

And the most important features of Post-process are:

• Load simulation result Layers.
• Create and View Video from simulation layers.
• Elevation Graph Tool.
• Time-dependent Graph tool.
• Create and View Velocity Vectors.
• Create and View Velocity Contour Fill
• Distance, Area, Volume, Flow Rate tools.
• View Results in 3D Viewer.
• Run and View 3D Simulations results.
