Toolbars within the header block of ArcGIS can be updated via the drop menu item (Customize >> Toolbars) or alternatively by right clicking within the header block. Commonly used toolbars for TUFLOW modeling are listed below:
- Edit Vertices
- ET GeoWizards
- 3D Analyst
- Create Feature, used to define what feature types will be created.
- Edit Tool, used to select a feature which already exists for editing.
- Edit Vertices, after selecting a feature using the Edit Tool, this selection will display the vertices of a feature.
- Trace, used to trace existing feature geometry when creating new features. The Layers which are selectable for the tracing can be managed using the selection options via right clicking a layer in the Table of Contents. This is shown in the figure below.
- Sketch Properties, after selecting a feature using the Edit Tool, this selection will display the geometry properties of a feature in tabular format. Values can be updated within the display, modifying the features spatial display.
- Editor>>Stop Editing
- Editor>>Save Edits
Snapping is used to associate point features with lines or polygons. ArcGIS snapping options include: Point Snapping, End Snapping, Vertex Snapping and Edge Snapping. Edge snapping is not recommended for TUFLOW model development tasks. Edge snapping can be disabled by deselecting the Edge Snapping icon in the toolbar. After being deselected, the Snapping toolbar should resemble the figure below.
Items within the edit toolbar are used to modify the location of vertices and add or remove vertices. The Edit and Edit Vertices tools within the Editor Toolbar need to be selected before the Edit Vertices options are selectable
ET GeoWizard is a central location for a wide range of geometry update tools. ET GeoWizard can be downloaded from http://www.ian-ko.com/ET_GeoWizards/gw_demo.htm. The most commonly used items within the toolbox are:
- Polyline >> Split Polyline
- Polyline >> Buffer Polyline
- Polygon >> Eliminate
- Polygon >> Fill Holes
- Convert >> Polygon to Polyline
- Convert >> Polygon to Point
- Convert >> Polyline to Polygon
- Convert >> Polyline to Point
- Convert >> Point to Polyline
- Convert >> Point to Polygon
- Geoprocessing >> Clip
- Geoprocessing >> Batch Clip
- Geoprocessing >> Erase
- Geoprocessing >> Batch Erase
- Geoprocessing >> Merge Layers
- Geoprocessing >> Split by Attribute
- Geoprocessing >> Split by Location
- Geoprocessing >> Transfer Attributes
- Miscellaneous >> Create Station Lines (Water Level Lines)
The 3D Analysis toolbar is used to perform analysis tasks on raster datasets. For example, cross-sections can be extracted from 3D raster datasets using the ArcGIS 3D analysis extension. This tool is useful for viewing and extracting creek cross-section or water surface elevation longprofile information.
The steps how to do this are outlined in the following webinar: Webinar Link: Extracting Cross-section Data From Raster
