Easy Trace enables you to create and verify complicated topological model of vector data. We consider any vectorizer without these abilities to be a tool for time waste.

All "raw" vector objects generated by automatic tracing belong to the same layer. However, quite often there are objects of different vector layers on the same thematic layer. There are a number of techniques for the rapid separation of objects on the necessary layers

At manual tracing, operators usually input much more vertices than it is necessary for correct reproduction of the data topological structure. It is much easier to put a lot of superfluous points than to find the real point of line inflection in the image... As a result, the project is overladen with excess data and its quality decreases.

Digitization often goes beyond simple object tracing and attributive data input; it comprises forming of an integrate and topologically correct polygonal cover. Easy Trace Pro has several useful tools and utilities for this purpose.

Polygons in Easy Trace are closed lines belonging to any layer marked as polygonal. The following operations are provide for polygons.

Explicitly, Easy Trace Pro dos not support multiply connected polygons i.e. ones, described by several disconnected boundaries. But it does not mean that there is no way to create polygons with holes.

One of the most commonly used Easy Trace Pro tools - "Breakup joining." Along with "Raw lines filtering" these tools are a powerful basis for after auto-vectorization processing . Effective use of these tools can dramatically reduce the time of manual processing along with the total execution time of vectorization.

Any big project involves, first of all, splitting a complex task into smaller ones. If you take a project digitizing large territory, the division into small plots and subsequent digitization is obvious. The problems start when one try to put the pieces together, and this need more detailed discussion.
