Map Window

• Controls

  • Information

This feature allows the user to display the numerical values of displacement parameters and deformation tensors. The information is displayed after selecting the desired arrow and either clicking on it, or dragging the frame.

Note: To view the information you need to have the layer "interpolated shifts" switched on.

• Zoom in

Click this button to zoom in the map. Similarly, the user can also use the mouse wheel.

• Zoom out

Clicking on this button zooms out the map. Similarly, the user can also use the mouse wheel.

• Length measurement

This function allows measuring length on the map. The result is displayed below the map window on the right.

To finish measurement, press the icon again.

• Area measurement

This function allows measuring areas on the map. The result is displayed below the map window on the right.

To finish measurement, press the icon again.

• Previous view

Undo move or zoom of the map.

• Print A4

Open print preview.

• Full area display

Displays entire area of the measured deformations.

• Redraw

Redraws the map (e.g. to view the new map layers).

• Map scale

The text box on the lower left side can be used to specify the scale explicitly.

• Pan Map

Arrows serve to pan the map in the direction of the arrow.

• Mouse

Use the mouse wheel to zoom in and zoom out. You can also zoom in by double-clicking the map. The map can be panned by drag the left mouse button (moving the mouse while holding the left button pressed). You can select a rectangular area to zoom to by holding down the shift key while dragging the left mouse button.

• Inserting user layer

This tool enables inserting a user defined layer, see Inserting user layer .

• Change the title

You can change the title of the map by using this tool (used mainly for printing).

• Save View settings

User can save the current state of the application (the displayed results, scale of the map etc.) and later return to it by loading the appropriate view. Clicking the button opens a dialog to enter a view name.

• Calculation shift and strain tensor in given point

This feature allows you to calculate the shift and the strain tensor at any point. First, click the button, and then select a point in the map (by cliking on it). Deformation tensor at this point will be calculated and displayed.

• Map Layers

Map layers serve as underlay for deformation tensors displayed in the map window. After selecting the map layer you need to press "redraw" to display the layer.

If you need to display a WMS layer that is not listed, please contact the application administrator. Another option is to use user layers.

• Recalculation

Recalculation make possible to change the scale of displacement and deformation tensors.

This function also deletes all custom tensors created with "Calculation shift and strain tensor in given point" tool.

The option "Show also unreliable" displays all the calculated tensors and shifts, even if they are unreliable.

• Export, output

The export and output tools allow to export the result in various formats.

• GML

Exports results into the Geography Markup Language format.

• KML

Export into Keyhole Markup Language , which you can see in Google Earth.

• SHP

Exports the results into the ESRI Shapefile format, widely used in GIS' to store data.

• 3D

Displays tensors in 3D. To view you need to have Java Virtual Machine installed.

• SVG

Exports to Scalable Vector Graphics.
