Support of local database SQLite for display of raster data in the form of tiles is implemented. There is added a restriction of the displayed geoportal area, set by the user in the settings file wmslist_en.xml. Support of local SQLite database provides also display of the matrix data about terrain in the hmp format and the execution of all kinds of computational tasks related with heights (construction of profiles, visibility zones, estimation of elevation, calculation of ground volumes, 3D modeling and other tasks). There is added a support for zip archives, encrypted by a user password, at performing the operations of opening the data sets (vector maps, images, matrices) and updating the open data. If the zip archive is encrypted, the user will be prompted to enter a password to access the data.
The task of "Map Editor" has been improved. New objects are located on the map at once, taking into account the order of the layers displaying specified in the classifier, without additional sorting of the map. To manage the order of recording objects on the map when sorting the map, a service file with the SIN extension is formed. If the SIN file was not created, then the objects are written to the map in the order of their type (polygon, linear, etc.). The mode "Creation of group of objects by coordinates from a text file" is modified. There is added the possibility to build orthodrome by the coordinates of the file MET - an arc on the Earth's surface, passing through the shortest distance between the given points. To execute the task in a text file with the .MET extension, you need the presence of the #ORTHODROME service field and two lines with the coordinates of the starting and ending points of the created object - the arc. At large distances (thousands of kilometers), the points of the arc are formed with a step of no more than 0.4 degrees, for small distances - no more than 10 kilometers, which ensures the determination of lengths and angles with triangulation accuracy of 1 class.
New property "Save time and date of object update" is added in the dialog of creating a new map. If the map is created with the specified property, then into each object, when creating and editing, service semantics are automatically recorded with the date and time of the performed operation and with the name of the operator that performed the operation. The specified property can not be disabled. Support of the pseudo-conical equal-projection of Bonn (EPSG:9827) is added. The new projection can be selected for maps of the Geographical type.
In the "Classifier Editor" in the "Layers" bookmark, there is added the ability to set the order of displaying objects within a given layer (the button "Objects order"). It allows to unite layers of the same-type in the classifier which have been entered earlier for management of order of objects display. Flexible setting of the classifier simplifies the preparation of libraries of conventional symbols according to the requirements adopted in the national mapping systems of different countries. There is added the accounting for multipolygons when searching for objects by a given area, taking into account the occurrence, intersection, location at a given distance.
XML format is used for storage of conditions of search and display of map objects in files with "vclx" extension in the "\Log" folders. This simplifies the work with program settings from external applications. The dialogue "Select object" is refined. On the "Metric" bookmark a map window has been added with the ability to display the section with the current point of the object's metric. This allows you to view the contours of extended objects and to correct the coordinates of points without leaving the dialog.
Due to multi-threaded processing on a multi-core processor, the execution time of operations on lists of objects is reduced by 6-8 times - a search for intersections, occurrences, location at a given distance, and so on. Speed of constructing the list of the found objects is increased in 2-3 times. The sorting of multi-sheet maps (MAP) is accelerated by 3-4 times. When sorting map objects, the order of displaying objects in the layer is taken into account.
In the program the dialog "Image color adjustment" was refined, which is called via the menu item "Options\Colors" in tasks of "Data lists" or "Map legend". There is implemented the possibility of creating and editing a set of the user palettes to control the displaying the matrixes of terrain elevation that were added into the document.
