I'm new to digitization. I have the following map and I'm trying to digitize the purple features. Is there any way to automatically digitize all the purple lines on the map.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • I'll assume that you are using ArcGIS for Desktop rather than asking what GIS software you are using and waiting for an answer, or needing to close your question as too broad. – PolyGeo Sep 3 '16 at 6:15

You can use ArcScan extension of ArcGIS for this. This is pretty much easy for auto digitizing such simple map with ArcScan For more information you can check http://desktop.arcgis.com/en/arcmap/latest/extensions/arcscan/arcscan-tutorial-interactive-vectorization.htm

Assuming that those lines are not polygon boundaries, and that you are using ArcGIS for Desktop, I would try to use the Raster to Polyline tool which:

Converts a raster dataset to polyline features.

If they are polygon boundaries then try the Raster to Polygon tool instead:

Converts a raster dataset to polygon features.
