Lesson 7 - Vectorizing an Image - Tutorial

The Image | Vectorize Image command converts a raster image into a vectorized data set of polylines and polygons. In the vectorize image example, we will use an image containing contours and automatically create vector lines of those contours. Once the contour lines are created, we will automatically assign elevations to the polylines.

Tutorial VLines.pjt contains a

simple contour map from which we

can create vector polylines automatically.
