Easy Trace Pro 8.6.1568

  • Create Project Wizard is improved. As remote processing of projects (by students - freelancers for example) becomes widespread, project mobility is more important now. That is why a strictly standard directory tree is provided together with automatic copying of all the data required for remote work.
    • Easy Trace automatically generates a standard folder at project creation for all the images linked to the project;
    • The "Copy raster to the project folder" option is added; the image will be copied together with the registration file, if exists;
    • the project scale field is corrected (previously, rounding at DPI-based calculation generated inaccurate figures - 10018 instead of 10000 and so on).
  • The Raw Line Filtering utility is the main tool at vector line preparing for reconstruction of their arc-and-node model after automatic tracing. It automatically detects and repairs typical flaws of vector line connectedness. In some map sheets it may do dozens of thousand alternations of vector data. That is why any improvement of the utility is extremely time-saving. So:
    • new processing of T-junctions is added. These may be river tributaries, junction points of polygon boundaries, etc. The processing should be done separately, after correction of other vector artifacts;
    • Artifact correction is based on analysis of connected vector objects' lengths and angles. The thicker are lines in the image, the larger is the zone of uncertain direction near nodes after automatic tracing. The program calculates directions now with a setback from nodes. The setback value depends on the thickness of raster lines;
    • priority processing of artifacts is added. The change the priority (execution order), move the artifact name up or down in the artifact list;
    • current parameters of artifact search and correction may be saved as a strategy. There may be several strategies in the project prepared for data of different types - relief contours, roads, hydrographical objects, etc. It is possible to import strategies from another project. Import overwrights strategies of the same name, add new ones, and does not alternate the rest.
  • The Outline Contours utility may be used rather non-typically. For example, good tracing of small lakes in the centerline mode is rather problematic. Their contours "collapse", thin and elongated contour parts may be clipped. But lake outlining may work almost ideally. As resulting contours are a little widened, the utility has now an option for compression/widening of contours received by tracing along outer or inner boundaries.

  • The Autodetect Lakes utility is improved significantly. It has preview now, and the objects to be recognized may be specified on the screen directly. Some new options are added:
    • cutting-out of inner polygons (islands);
    • deletion of "rubbish" objects within recognized polygons;
    • merging of adjacent polygons;
    • saving of recognition strategies;
    • an area is added for context help on all parameters of the utility;
    • the algorithm of adjacent polygons merging and search for inner polygons is improved.
  • The Autodetect Circles utility is completely revised. Both utility design and the concept of use are changed. The utility may seem to be not so useful at first sight as round objects are rare in maps. On the other hand, there are a lot of topographical signs based on circles, and application of the utility depends on your imagination...

    The simplest way to use the utility helps to "discharge" the project after automatic vectorizing. After deletion of circles, it is easy to restore lines that were adjacent to them in some way.

    Automatic vectorizing of dot lines (borders of vegetation) gives another example. You may outline outer contours of dots and then recognize them as circles. Transform them into strokes and fulfill Breakup Joining to get accurate boundaries.

    Another example - automatic tracing of altitude marks. Outline outer contours of the marks and transform them into points. Then mark the points and use automatic navigation to review them and input altitude values (and delete irrelevant ones).

    • First stage of recognition is assessment of diameter size distribution in the image. The distribution is represented as a frequency diagram;
    • You may specify diameter ranges for circles to be ascribed to different layers in the histogram directly and place them into the table;
    • You may edit these diameter ranges in the table or by selection of circle examples on the screen;
    • Preview mode of the utility shows you objects that will be recognized as circles at the current set of parameters. To correct parameters, just click objects on the screen.
  • The Autodetect Orthogonal Objects utility is changed:
    • the interface is altered;
    • an area is added for context help on all parameters of the utility;
    • saving of recognition strategies is provided. Once selected parameters may be used in all projects - clones.
  • The Generate Inscriptions utility is a powerful tool that let you control correctness of object attributes. Attribute input may be very unhandy in case of a complex polygonal coverage composed of thousands of polygons (soil maps for example).

    The Group Editor enables quick input of identical attributive values for a group of polygons. But it was impossible after generation of inscriptions to correlate uniquely a polygon and the inscription that corresponds to it. So, check-up of attribute data correctness was difficult.

    To avoid the indeterminacy, the insertion point of every inscription is now always placed within the corresponding polygon.

  • The Polygon Subtraction utility is added to the Topology group. It is intended for coordination of polygonal layers with common boundaries. A typical example is subtraction of polygonal objects - "islands" from polygonal objects - "lakes".

    To control correctness of alternations at subtraction of polygonal layers, you may mark polygons responsible for common boundary forming during the operation. Use the automatic navigation for quick review of all marked objects and check-up correctness of the alternations.

  • The Create Polygons utility has now the "Cut out inner polygons" option. When you form a polygonal cover on the base of the arc-and-node model, you needn't any more search and cut out embedded polygons manually. Together with automatic tracing and processing of T-junctions (a new option of vector filtering), this option dramatically accelerated vectorizing of complex polygonal coverages.

  • The Convert Objects new utility has systematized options of object type transformation. The utility enables some unusual methods:
    1. Use the Topology Check-up utility to find crossings of rivers and roads;
    2. Convert error marks at the crossings into point objects (bridges and fords);
    The utility makes all reasonable conversions of object types including exotic ones ( "circles - strokes "). So:
    • the utility has substituted options of block and circle transformation previously accessible in the editing mode;
    • the utility enables mutual transformation of all point objects: points, blocks, circles, error marks, text;
    • the utility may be activated both from the Utilities menu and Editors' submenu (for conversion of selected objects).
  • Shears: polygons completely coincident with a cutting contour are protected from changes. It means that when you select lakes as cutting contours (to delete ends of river lines inside them) you may be sure that the lakes themselves will not be cut out.
  • Some improvements are made in the Contras Enhancement raster tool:
    • output ranges should be adjusted separately for every color channel;
    • maximum and minimal limiters of the sliders in the ranges correspond to 0 and 255;
    • better evaluation of ranges at automatically determined percentage loss;
  • The Diffuse and Unsharp Mask raster tools apply a round mask now. The factor in the Diffuse dialog box is changed.
  • The Resample and Color Mode (adaptive palette) raster tools works in the multithreading mode. Color distortion at stretching with interpolation (up to 10% of brightness) is corrected.
  • Cyclical selection of images linked to the project is provided for the Crop/Clip tool. To select the image, press down the Shift key and click the mouse left button.

Bug corrections

  • The bug is corrected that hung the program at image opening from a project if the working window was divided with the help of the Window -> Split command.
  • The bug is corrected that caused sometimes a fall of the program at new layer creation (for example, if the only layer was one called "0")
  • Tool bars "remember" their position now; the program shifts the working window if the bar is outside it.
  • The bug is corrected: incorrect default values of attributes of the "Date" type.
  • Clipboard bug is corrected that caused a fall of the program.
  • The bug is corrected at color mode transformation into 256 colors (adaptive palette).
  • The bug is corrected that caused a fall of the program at object editing / deletion if the attribute table was opened.
  • The Eraser tool could cause a fall of the program at polygon deletion in the vertex deletion mode.
  • A wrong message is corrected at 3D polyline processing by the Camber Editor.
  • The bug is corrected: the Undo command didn't function after automatic detection of the grid.
  • The Undo command after Line Form Optimization works significantly (8 times) faster
  • The bug of the Create Polygons utility is corrected: if there are more than 8190 vertices in a polygon, the program automatically divides it now and forms two polygons.
  • Import from the SHP format could be interrupted by the "out of Memory" message (for files containing invalid records). Now, the program informs you about incorrect file format and tries to search for the next valid record.
  • Bugs of project creation are corrected:
    • project field was inaccessible for editing without an image
    • after a change of projects units, they were incorrectly represented in the fields of coordinate field borders.
