GIS Shapefile Data: Modify
After using the Control page to read in shapes from a shapefile but before placing them on the diagram, the Modify page can be used to modify the XY attributes of the shapes.
There are two map projections you can choose from when placing the shapes onto a oneline diagram. The choices are:
- North American (simple conic)
- Entire World (Mercator)
Once you have selected which projection to use, click on the Convert to Specified Map Projection button to process the conversion on the shapes currently in memory.
Shift/Scale Shapefile X/Y Data
You also have the option to shift the XY coordinates of shapes or scale them by scalar values. To shift shapes, enter scalar shift values for the X value and Y value and press the Shift XY Data button. To scale the XY coordinates, enter scalar scaling factors for the X and Y value, and press the Scale XY Data button.
