The program improved display of rasters with cutting the images by a frame for various scales. This allows you to more accurately display the mosaic of rasters without discrepancies and overlaps of adjacent raster image when zooming. New implementation of forming the images of the raster's reduced copies allows to improve details of the survey image.
Converter from SHP format is improved. The converter adds support for file names, field names and attribute values in the national encoding. There is added an automatic identification of the set name and the classifier object (by key or name). Possibility is implemented for creation of the new classifier with the subsequent primary automatic classification of objects and characteristics. Tools are added for customizing the protocol's content of the initial data composition.
There is improved the task "Assemblage of symbolical semantics" intended for forming the character string as the value of the semantics and assignment of this value to the marked objects. To the list of the original semantics of objects there is added the list of keywords for recording into semantics of metadata of object or of a map (the date of the terrain state, the nomenclature of the map sheet, GUID of a map sheet, object name, layer name, security classification and others).
In the task "Map Computer" there is modified the mode "Information about the object". The mode allows you to collect the data about the terrain object consisting of a great number of separate parts, by the object identifier (the road number, the river name and so forth). Into dialog the options are added that allow you to collect the object from parts of different layers. It allows to receive more complete information about the object in general and the distribution of properties (semantics) by individual parts.
In the dialog box "Select object" there is changed the algorithm for calculating the area of the objects having extent on a longitude more than 5 degrees. Extended objects are cut by strips in UTM projection, no more than 5 degrees on a longitude. The total area of objects is calculated by conventional zones and summed. The extended accuracy of calculation of the area is provided at a selecting the "Clarify the area and length" in the menu "Options" and a choice in Select Object dialog in the pop-up menu for item "Accuracy of coordinates display" of the value "Extended".
In dialog "Search by address" to specify the name of the desired street there is expanded the list of types of semantics. Possibility is added for search of streets by semantics with type "Code from the classifier (directory)". The choice of the name of street is executed from in advance prepared list in the classifier.
In the module "Geodesy calculations" a processing of orientation angles is improved. Position of any object on the ground is specified in a format of orientation angles between the initial (specified) direction and a direction onto object and distance to the object. Orientated angles of directions are: rotary angle, direction angle and rhumb.

Access to the data (to the images, vector maps and information on the terrain) Web-services provide according to conventional OGC protocols and ISO standards. Service of the
GIS WebServer SE is used in the construction of private enterprise systems to ensure protection of data having security classification or trade secrets. GIS WebServer SE is certified to Level 2 of undeclared capabilities absence. The new version of the program extends the application's possibilities in solving problems of the analysis, management and forward planning of territories development. GIS WebServer SE is implemented with use of toolkit the GIS WebToolKit SE which can be applied in the development tools using the JavaScript.

In KB "Panorama" the researches have been conducted by definition of optimal parameters of the server's work for the publication of the geospatial data according to the international standards OGC WMS and OGC WMTS.
The vector maps and remote sensing data, located on the
Made testing has allowed to increase number of web service clients. Maximum productivity has been achieved for WMTS standard (vector data) - 420 users per second, for WMS standard - 27 users at the limited resources of the server.
