A picture paints a thousand words. We hope this video will not only help give you an idea about the package, but also form the basis for auto digitization technology for your materials. Good luck!

Demonstration of the spline mode, which lets you create the curves of complex shape.

Speed is often the most priority characteristic at space imagery decoding. "Imagery decoding for address plan making" video demonstrates the speed achievable in Easy Trace Professional and explains the method it is based upon

Small improvements of the Orthogonolizing and Rectangular Tracers enabled dramatic acceleration of address plan forming. The work is mostly based on use of preliminary decoded objects

Why not allow main tools to be universal? It seems reasonable to make tool functionality dependent on situation around the cursor rather than to juggle with several tools all the time

Operating environment is focused on rather uncommon tasks to be solved in an unusual way that differs from one that most software packages apply. Something you have never worried about may become a key term of effective work. But everything is easier than it may seem to be...

Use of georeferencing files is the simplest method of image adding to your project. It enables adding of several images at once that may be very useful at assemblage of large mosaic coverages

As a rule, this method is in use at an intermediate stage with subsequent exact correction based on all cells of the grid. Another case - adding of an already corrected image

Our approach to digitizing of dotted lines is quite applicable for recognition of elevation marks. There may be several hundreds marks per map sheet and the share of correct recognition runs up to 80-90%...

Low resolution of the image is not a good reason to refuse from automatic digitizing. You may achieve an impressive result even in free version Easy Trace 7.99

Extraction of thin lines drawn on the sepia background is a non-trivial task. Hardly visible remnants of lines are mixed with sepia points in the overcompressed JPG file. Suggested technique enables you to extract such lines even by means of free version Easy Trace 7.99

This technique enables you to load WEB imagery for vector data updating. Exact positioning of the photo relatively the image is simple and convenient

Image correction at map sheet georeferencing is usually based on several points of the map frame. It does not act upon distortions inside the frame. No wonder therefore that we often hear about low exactness of topographical maps. Our technique implies image correction based on ALL CROSSINGS OF GRID LINES. A special utility is provided for automatic recognition of the lines

There may be several thousands of small ortho-objects in a sheet of 1:100 000 topographical map. The technique allows you to recognize up to 90% of such objects automatically

Data-loaded map images contain a lot of objects dissected into small patches by grid lines. These lines may distort and destroy thematic information. Grid extraction and deletion from the image notably simplify further digitizing. On the other hand, information about exact grid line position in the map makes image correction an order more accurate

Relief digitizing is one of most laborious tasks but automatic digitizing makes it tens times faster. Effectiveness of this procedure completely depends on quality of the source image. Unfortunately, color-separated map originals are unavailable for most common users. That's why we demonstrate processing of an image after lossy compression by JPEG format

This technique restores line integrity and automatically deletes numerous defects. All stages of relief digitizing are automatized including check of form and topological connectedness as well as input and control of elevation values

This technique enables you to extract swamp strokes from a color image and restore polygons of swamps in the automatic mode. Polygons formed by a special utility out of strokes require only minimal correction. It took only 16 hours to form polygons of 4 853 swamps applying this method

The technology allows to select from a color screen automatically digitize and convert polygon and line features of the hydrographic network. Even heavily loaded topographic map containing several thousand objects, digitized at 2-3 shifts operator

This technique enables automatic digitizing and recognition of dotted lines. Easy Trace forms the arc-and-node model out of generated smooth lines and thus automatically restores the polygonal coverage defined by them

This technique enables forming of a continuous polygonal coverage on the base of polygon borders. A low-quality color image with much of irrelevant noise was taken for the example. Automatic restoration of line integrity and deletion of "rubbish" by special utilities made manual editing of vector data minimal. It took less than 12 hours to digitize 4324 polygons and to input their attributes

The proposed technology allows consistent "unload" saturated pads, providing access to the automatic identification of objects of different types. Manual digitizing is almost never used

Use of the Topology Correction utility dramatically accelerates editing at automatic digitizing. The utility is equally useful for improvement of prexisting low-quality vector data

The Point tool is one of the simplest. It takes one click to generate a point in Easy Trace. But search for point objects in the image is a long and tedious work. This video shows how to make it quickly

Camber Editor is an original tool, which, when invented, had no analogues in other digitizers. It is rather difficult to describe its principle of operation in words but it becomes intuitively obvious after several experiments. The tool is intended for forming and editing of smooth curves

Vector Eraser is an universal and frequently in use tool when it comes to dismantling of automatic digitizing results. It enables you to improve line form in three ways - to "cut off everything unnecessary", to separate falsely joined lines, and to delete "rubbish" objects
