Fluviz

is a spatial data processor that has been written as a companion for two-dimensional flow modelling tools (e.g. Flumen, Hydro2de, TriPaD). It consists of modules for the generation of structured data sets from scattered data points. The code can be used to edit existing sets (e.g. topographical data) and performs calculations with given sets.

On Screen Data Editing Data Editing and Altering

cutting points and vertices

contour query

data operations (+,-,*,/,<,>)

closed polygon editing

Weeding of Vertices (Douglas-Peukert) Data Filtering

buffering (removing points near edges)

cutting equal nodes

closing polygons

weeding of vertices (with Douglas-Peukert algorithm)

Quadrant Search Method Surface Interpolation (Gridding)

nearest neighbour

distance weighted and quadrant search

constrained Delaunay triangulation

Mapping on TIN Mapping and Data Query

mapping of nodes to given TIN

mapping sections to given TIN

extracting river sections from TIN surfaces

since version 3.0:

unlimited mesh sizes (depending on system RAM)

generation of optimised meshes with variable cell areas (CFL-condition)

Fluviz is based on the grafic library GraficV3 (copyright MIT). The triangulation is performed with the program Triangle.
