Convert Line to Polygon using MNDNR and Edittool (ET)

Convert Line to Polygon using MNDNR and Edittool (ET) line-to-polygon For digitizing a map we need accuracy and precision in making the boundary line. However, the weakness of the line or polygon is very difficult to make a line corresponding to the lines on the original map. On this occasion I will show you how to makes a polygon using a line that was converted into a polygon polyline later. First and foremost we have to add the extension (ext)...
