Cross Section Viewer

 

In Hydro GeoAnalyst, you can use the Cross Section Viewer Module to create, edit, and display cross sections with representations the geology, hydrogeology, and modeling layers and add Well Profiles of selected boreholes.

To Open the Cross Section Module:

Click the Map Viewer [] button on the main toolbar
 or

Select Modules > Cross Section Viewer from the Main Menu

 

Layout and Interface

The Cross Section Viewer consists of the following controls:

Cross Section Toolbar provides tools and access to features that help manage, edit, and visualize the active cross section interpretation

Settings Toolbar and selected feature settings provide access to view and edit settings for components within the cross section

Cross Section Viewport displays visible cross section features

Topology Inset Map displays the location of the cross section, associated stations, and intersecting cross sections

Status bar: display the coordinates of the mouse pointer in the Cross Section Viewport

 

Cross Section Toolbar

The Map Toolbar provides controls for managing the map:

 

Cross Section Tools

Save: save changes to the current Cross Section in the Project Tree.

Save as...: save a copy of the current Cross Section with a new name in the Project Tree.

Rename: rename the current Cross Section.

Refresh: refresh the cross section and associated data in the current viewer.

Select Stations: add/remove/reorder stations along the cross section.

Interpretation: select the active interpretation type in the current cross section:

geology: interpretation based on lithology structure data

hydrogeology: interpretation defining the structure/locations of hydrogeologic layers (e.g. aquifers, aquitards, and/or aquicludes)

modeling layers: interpretation defining the model layers which may be used in numerical groundwater modeling)

 

Clear Interpretation: reset the interpretation to a blank polygon that is bounded by:

the extents of the cross section line (as defined in the Map Viewer or by the Select Stations [] button described above),

the defined surface at the top, and

the depths of the added boreholes (and intersecting cross sections) on the bottom.

 

Auto-generate: reset the interpretation based on the borehole intervals (and, optionally, the intersecting cross sections)

Show lines: toggle the visibility of the borehole and intersection lines

Show wells: toggle the visibility of the well intervals

 

Interpretation/Editing Tools

The following tools are available for working with interpretations:

Pick Mode: select features in the cross section, including the polygons, line sections, and vertices that define the cross sections. Settings for the selected feature will be shown in the settings panel on the left of the viewer. Selected points/vertices can be moved (drag and drop) when the pick mode is active; however, lines and polygons are fixed in place.

Add Points (I): insert vertices along the boundary of a cross section polygon

Delete Points (D): delete vertices along the boundary of a cross section polygon

Connect Points (C): connect vertices to split a cross section polygon into two parts

Merge Polygons (M): merge two or more polygons:

click in the first polygon to select it as the polygon that subsequently selected polygons will be merged into

click on adjacent polygons to merge into the first polyon

 

Please Note: there is no undo button for individual edits/actions. However, if you exit the Cross Section Viewer without saving changes and reload, you can revert to the cross section to the state before it was saved to effectively undo all changes since the previous save.

 

Viewer Tools

Pan (W):  pan around the cross section view. When this tool is active (framed in a solid blue line), you can:

click and drag the mouse pointer on the map to pan around

use the mouse wheel up/down to zoom in/out, respectively

 

Zoom In (+): zoom in on the cross section view

Zoom Out (-): zoom out on the cross section view

Zoom to selected area: zoom in on the cross section. When this tool is active (framed in a solid blue line), you can:

click, drag, and release to zoom in based on the scale of the resulting rectangle to the current viewport

 

Zoom to full extent (Home): zooms the viewport to the full extent of the cross section

Exaggeration: sets the vertical exaggeration of the cross section. This component is disabled if the Fit-to-screen setting is active.

Fit-to-screen: if active, sets and locks the vertical exaggeration of the cross section so that the aspect ratio of the cross section fills the screen.

Viewer settings: opens general settings for cross sections, including the Axes, Topology, and the Legend.

Export to images or presentation: exports the current cross section to an image or PowerPoint template

Label format: the label text. Automatic values from fields are entered as the station table field name (not alias) wrapped in {} brackets. For example, the Station Type would be entered as {stn_type} as shown above.  To add a field to the label, simply double click on the desired field in the Available fields list.
 

Available fields: the list of fields from the Station List table.
