Geographic Information System (GIS)

SADA can read and overlay pictures with a layer that has been produced by a Geographic Information System (GIS) and saved in a Data eXchange Format (DXF). To add a layer to your data or modeling results, choose GIS from the main menu and select Layer Control. The following window appears.

To open another layer press the Open DXF button. To close a layer, select the layer and press the Close DXF button. To change the position of a layer in the layering scheme, press the Layer Up and Layer Down buttons. To make a layer visible, check the box next to the name under the Show Layer column. To change the Layer Color, click the corresponding Layer Color box and choose a color from the Pallette window. To view your changes, press the Apply button.

The LayerControl window has the following toolbar buttons.

Open/Close – Opens and closes the DXF layers, respectively.

DXF Position – Moves the selected layer up and down, respectively, in the GIS layer ordering.

Apply – Redraws the current GIS layering scheme in the Graphics Window.

The layer control window must be closed in order to return to the main SADA interface. To turn off the GIS layer system, select Show Layers from the main menu (Show Layers will be unchecked) in SADA. Repeat this process to turn the GIS back on (Show Layers will be checked).

For three-dimensional applications, the GIS image is available only for the Easting-Northing layer.
