These data have been produced by photogrammetric methods and by scanning, tagging, vectorizing, and gridding of hypsographic map separates. |
|
A novel method for vectorizing construction engineering drawing images is presented. |
|
Moreover, vectorizing breaks the natural structure and correlations in the image data. |
|
It is an ease of providing rapid and precise image scanning, editing, cleanup, manipulation, vectorizing, improvement, annotating, redlining, conversion of CAD and raster formats. |
