This page contains a brief introduction to the ArcGIS software. A number of ArcGIS tasks which are repeatedly used in creating a TUFLOW model are described below, each of these has a separate page. If you have any suggestions to be included in these pages, please add them to the discussion page. Please add ArcGIS Suggestions Here!.

Shapefile Naming Conventions

In these ArcGIS shapefiles different object types (points, lines and regions) are stored in separate files. When TUFLOW outputs in shapefile format, each file ends in:

  • _P to indicate a point file;
  • _L to indicate a line file; or
  • _R to indicate a region (polygon) file.


This section outlines some basic GIS functions that are regularly used in creating TUFLOW models using ArcGIS.

  1. Create a projection file for TUFLOW
  2. Toolbar customization
  3. Create a grid from points
  4. Convert raster to .asc format for direct read in TUFLOW
  5. Convert raster to .flt format for direct read in TUFLOW
  6. Point Inspection from Raster

Tips and Tricks

  1. Labelling messages file
  2. Convert lines to points
  3. Assign raster value to points (point inspection)
  4. Extract breakline for TUFLOW import
  5. Hotlink to External Files
  6. Extracting cross-section or long-profiles from raster data
  7. View raster value
  8. Changing a files projection
  9. Thematic mapping (Symbology)
  10. Creating an Animation
  11. Creating 1D Water Level Lines
  12. Creating a Google Earth KMZ file
