Hello Yang, For approximately even point spacing you could do this...
// for each feature Geometry line = (Geometry) lineFeature.getDefaultGeometry(); Geometry lineWithExtraVertices = Densifier.densify(line, maxPointSpacing); Coordinate[] pointCoords = lineWithExtraVertices.getCoordinates(); See javadocs for the Densifier class: http://tsusiatsoftware.net/jts/javadoc/com/vividsolutions/jts/densify/Densifier.html You don't say whether you want to work with the output points as Geometry (Point) objects or create SimpleFeatures from them. If the former, you could use the Geometry.setUserData method to store the id of the parent line feature. If the latter, you can obviously just have a point feature attribute for the parent id.
