Resource saving meshes for 2D hydraulic modeling,
topography and flow adapted for optimum accuracy
Optimized GIS pre- & post processing tools,
with focus on spatial accuracy
in levee and flood protection planning

New in Version 2.0: Improved Graphical User Interface

AMG 2.0 GUI

AMG 2.0 GUI

What does AMG2 automatically for you ?

Example:  Cell reduction and minimum cell size limitation with optimized object generalization algorithm

Buildings

AMG reduces the number of cells by simplifiying building shapes ...

Example:  Increasing  line object accuracy

Line Interpolation

Line interpolation in common GIS software and improved algorithms in AMG

Example:  Adaptive mesh refinement

Flow Adaption

Flow adapted meshing concentrates cells in areas with the highest impact on the overall project quality

Main Features:
  • Semiautomatic generation of  resource saving 2D hydrodynamic numerical models
    • Cut down calculation time by more than 90% compared to common Delaunay meshes
    • Increase accuracy within problematic zones
    • Adapts meshes to topographic and hydrodynamic heterogeneous regions
    • Maintains minimum and maximum values for cells sizes, to prevent short time steps
    • Especially designed for usage in wide range 2D-HN-models, for extended parameter studies or  operational use in flood protection projects
  • Preprocessing of Digital Elevation Models (DEM):
    • Interpolate gaps
    • Determine correlation length of  topographic features
    • Converts coordinate systems (uses additional PROJ4 plug-in)
    • Converts DEM from more than 40 formats in to grid file catalogs (uses additional GDAL plug-in)
  • Preprocessing of  vector data
    • Combines multiple Datasets provided as .shp, .asc, .lin or .mp-files
    • Deletes double and unnecessary information
    • Detects intersecting and incompatible data
    • Detects and combines point clusters and almost parallel lines
    • Builds 1D-Models along corridors in DEMs
    • Filters and substitutes element properties within defined zones (e.g. elevation =< 123.45 m.a.s.l.)
  • Automated mesh manipulation
    • Selective (rule based) cell property manipulation for case studies (e.g. elevation, land use, roughness)
  • Post processing
    • Rasterize and georeference mesh attributes
    • Calculate raster differences
    • Extract mesh properties (e.g.  elevation, flow, W.L.) along point and line features
    • Build streamlines from flow data
    • Build direction arrows in cell center or equidistant raster from flow data
    • Analyze mesh quality
  • Export georeferenced values as
    • Grid files (.bil, .asc)
    • Shape/ feature files (.shp)
    • Triangle TIN files (.ele / .node / .poly)
    • Property colored bitmap (.bmp, .jpg)
    • Property colored metafile (vector) meshes for export to common graphic and presentation programs in highest quality (.emf, .svg)
    • Property colored Google Earth (vector) meshes (.kml)
  • Keep track of your continuously growing and developing project files:
    • Automatically saves old file versions as ZIP compressed backup files, in case you prefer to go some steps back in work
    • Automatically saves project files:  Start where you left the day before
    • Every workstep is saved to a log-file, to remember the datasets and the methods used to build the model
