Engauge Digitizer
From CFD-Wiki
This open source, digitizing software converts an image file showing a graph or map, into numbers. The image file can come from a scanner, digital camera or screenshot. The numbers can be read on the screen, and written or copied to a spreadsheet.
The process starts with an image file containing a graph or map. The final result is digitized data that can be used by other tools such as Microsoft Excel, Gnumeric and Gnuplot.
