This utility lets you go to a Map and “draw” freehand on it on your computer.
It is called GPS Visualizer : http://www.gpsvisualizer.com/draw/
Instructions are on it.
To make a graphic with your drawing on it of the Bayou Corne sinkhole just enter “Napoleonville, La.” in the search box and you get a great (zoomable) map!
To save it you use the box in the upper right . . . OR . . . on a PC you hit the CONTROL key and the Print Screen key (it does a screen grab) and you open PAINT or other drawing utility and press CONTROL and ‘V‘ key. Do a ‘Save As…’ to your computer.
You can use the same trick to copy a flyover photo to your art utility to draw on it too.
The link will go also at the bottom of our MAPS page for easy reference.
