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.
