Engauge Digitizer - Digitizing Maps

The following steps manually digitize a map with one measure:

Obtain an image file (bitmap, jpeg or other) containing a scale bar with its scale distance marked
Import the image file using one of the following options:
- File/Import menu option
- Copying and pasting
- Dragging and dropping
Click on the Scale Bar button before entering the scale bar. This will define the scale
Click on one end of the scale bar, then drag to the other end of the scale bar, then enter the scale bar length
Select the View/Measure Geometry Info menu option to bring up the measure geometry window
Click on the Measure Points button before entering measure points. These will contain the measure angles, distances and areas
Click on the map to add a measure point
Repeat the previous step until the map is covered with a sufficient number of measure points
Export measure points using one of the following options:
- Copying and pasting to copy points in the current measure from the measure geometry window to another application
- Dragging and dropping to copy points in the current measure from the measure geometry window to another application

For a map with more than one measure:

Select the Settings/Measures menu option to bring up the measures window
Click on the New button to create a new measure, then enter the name of the new measure
Repeat the previous step until all desired measure names have been entered
In the main window, use the Measures combobox to select a measure. While that measure is selected, all new measure points will be assigned to that measure
