In KB "Panorama" the GIS WebService SE version 14.4.1 has been developed. In the new version the tools for creating thematic cartograms for arbitrary user objects have been added. Maps can be created to analyze geological, geographic, geophysical, engineering, and other data models. Types of objects are specified by primitives described in JSON (SLD) or xml (SLD) format. In this case, the type of objects may depend on the parameters passed in the request or be specified by a formula. Data for analysis can be transferred in an arbitrary text file, a CSV file, or located in object semantics. Tools for creating and using cartograms are implemented in GIS WebServer SE.

The service's capabilities for working with layers have been expanded. A request to get the state of the map has been added. It will allow to reduce the traffic for dynamically updated layers (for example monitoring of movement of motor transport) and not to receive a picture if the state of data has not changed. Possibility to limit scale of data output for a layer has been added. Possibility to set the type of data displayed for the layer is added: screen/printer. Support of transactions with graphic primitives in JSON and SLD formats has been added.

GIS WebService SE supports all international standards (OGC WFS, WFS-T, WMS, WMTS, WCS), which are used to transfer and display spatial data. The program implements the ability to issue tiles according to any user or local coordinate system. The application is implemented on Windows and Linux platforms and is compatible with Apache, IIS and nginx web servers.

The new version of the program and documentation are posted on the website in the Download section.

In KB "Panorama" the professional vectorizer "Panorama-editor" version 14.2.1 has been developed. In the new version the tools have been improved for checking the quality of topographical and special maps and processing of matrixes of heights, editing of spatial databases in information systems, automation of constructing and updating the diagrams for the territory analysis.

Requirements for the accuracy, content and format of the electronic presentation of state topographic maps and the state topographic plans are established by order of the Ministry of Economic Development of Russia dated 06/06/2017 № 271 "On approval of requirements for state topographic maps and state topographic plans, including requirements for the composition of information displayed on them , to the conventional symbols of the specified information, requirements for the accuracy of state topographic maps and state topographic plans, for the format of their presentation in electronic form, requirements for the content of topographic maps, including relief maps" (registered in the Ministry of Justice of Russia on July 03, 2017 № 47276).

In accordance with the requirements of Order № 271, the task "Check of vector map quality" has been improved, which is designed to check the structural integrity of digital data, the completeness and quality of the metric and semantic description of objects, and to automatically correct detected errors. In the mode of control of self-crossings and location of subobjects, additional processing has been added: search and removal of matching fragments of the contours of linear objects, control and correction of flags for the occurrence of contours of multipolygons. The task is started via the main menu: Tools - Run Applications - Check of vector map quality.

The task "Control of absolute heights" has been improved. Into the profiling mode "By triangulation" there are added a processing mode "By sheets" and the ability to select individual sheets of the region using the "Filter" button. The "By sheets" mode does not detect erroneous elevations differences between objects of different sheets, but it is performed 5-6 times faster than processing in the region, since triangulation is built for each sheet separately with a smaller number of edges (profiles). For the processing mode in the region, the issuance of unnecessary messages caused by the passage of profiles through the areas of sheets absence in the case of a non-rectangular form of region has been eliminated. Processing time indicator "Time (used/remain)" has been added. For a flat terrain with a large number of elevations and a small number of isolines, the "By triangulation" profiling mode eliminates misses that are possible when searching for heights in horizontal and vertical directions, which reduces the number of uninformative messages and facilitates the analysis of control results.

The procedure for correcting object metrics has been improved: search and removal of shuttle and spiral self-crossings has been added, statistics output on corrected and uncorrected errors has been added into the message log (Map Editor - View map control log). The procedure for correcting the metric is started through the main menu: Tools - Processing map by scenario - Correction of objects metrics.

There are added the new types of programmable signs for displaying pie and column diagrams according to the semantics of objects. The description of diagrams includes a list of codes of semantics corresponding to sectors of the diagram. Each semantics has its own sector display parameters (color of filling, contour color, filling with shading and others). For a pie diagram, the parameters of the contour line and the size of the diagram radius in mm are set. The conventional symbol the Pie diagram is shown in the data example on the map \Data\shape.

The dialog for setting the view of a hatched areal object has been improved: the choice of a translucent line type (Line - color glass) and the setting for shift of hatching have been added. Use of imposing of two or more hatched views with different shifts of hatching allows to receive hatching of double, multicolor or other more complex views. Object type setting is performed in the map Classifier Editor or in the object selection dialog (on the "View" tab). The conventional symbol the Hatching with offset is shown in the data example on the map \Data\shape.

Possibility of automatic selection of editable tables of spatial databases has been added when updating multilayer cartographical representations of data. Objects of a digital map that displays the state of a spatial database are stored in various tables with their own sets of attributes. Objects from different tables can be displayed by conventional symbols from one classifier containing the corresponding layers and types of symbols. Database tables do not contain metadata that restricts recording the new objects from "alien" layer. The operator should choose a layer on which the object will be put from a large list, which slows down the work and introduces errors. To automatically determine the table to be updated, the ability to set filters by layers, objects, and a set of characteristics has been added into the settings of connected databases.

The new version of the program is available for download in the Download section.

Specialists of KB "Panorama" prepared and placed the map of the Novgorod region on the geoportal "Bank of spatial data". The map was formed using OpenStreetMap data, source data was obtained from Geofabrik website. To work with the map, you can use the GIS Panorama Mini program or other software products of KB "Panorama".

The map was led to the modernised classifier of large-scale plans of scale 1: 5 000 (map5000m) and was saved into a packed project (mptz). The MPTZ format project includes a digital map of the region's territory (country, subject of the federation, administrative region), a map of the administrative-territorial division of the region and a digital classifier. Publishing of updates in bank of spatial data is made by using the program of Databank of digital maps and remote sensing data. Publishing contents of bank of spatial data on the geoportal and data access for downloading are implemented by means of GIS WebServer SE.

Free maps on the basis of OpenStreetMap data are available for download on the page "Digital maps".

In KB "Panorama" the "Complex of 3D analysis" version 6.3.0 for the GIS "Panorama" has been developed. The complex is designed to create surface models and solve problems of spatial analysis using the constructed models. In the new version of the program, tools for combining matrixes of elevations and tools for profiling the terrain surface have been improved.

In the "Summ elevation matrixes" task, the "Rejection of matrixes with elevations outside the specified range" mode has been added. The mode is intended for estimating the elevations of a set of united matrixes and determining the composition of data with reliable elevations. Matrixes with elevations outside the specified range are removed from the list of matrixes and moved into a separate directory. The "Summ elevation matrixes" task is intended for creating a file of matrix of elevations according to one or several open matrixes. Task execution in a mode of smoothing of elevations allows to eliminate sharp differences of elevations of the resulting surface.

The profiling mode "By triangulation" of the task "Control of absolute heights" has been improved. There are added a processing mode "By sheets" and the ability to select individual sheets of the region using the "Filter" button. The "By sheets" mode does not detect erroneous elevations differences between objects of different sheets, but it is performed 5-6 times faster than processing in the region, since triangulation is built for each sheet separately with a smaller number of edges (profiles). For the processing mode in the region, the issuance of unnecessary messages caused by the passage of profiles through the areas of sheets absence in the case of a non-rectangular form of region has been eliminated. Processing time indicator "Time (used/remain)" has been added.

A new type of profiling of map objects has been developed - by triangulation edges. The triangulation vertices are: a point object (height mark, GGS point, waterline mark), a metric point of an areal object with an absolute height (lake, reservoir), a horizontal metric point.

For a flat terrain with a large number of elevations and a small number of isolines, the "By triangulation" profiling mode eliminates misses that are possible when searching for heights in horizontal and vertical directions, which reduces the number of uninformative messages and facilitates the analysis of control results. The "Profiling" task is intended for constructing relief surface profiles using the matrix of elevations MTW, TIN-model and MTD-model, as well as for displaying sections of geological layers and thickness graphs at a given point using the layers matrix (MTL).

The "Complex of 3D analysis" includes specialized tasks of relief analysis, modelling of derivative surfaces, creations of vector characteristics, tasks of forecasting and an accuracy estimation. The surface's model can display various properties of terrain, such as relief heights, concentration of pollution, amount of precipitation, level of radiation and others. Models of surfaces can be created by vector data of formats SHP, MIF, DXF, SXF, KML and others, according to information from database tables (DBF, XLS), and also can be loaded from formats SRTM, GeoTIFF, XYZ, LAS and others, in total more than 20 formats. Models of surfaces are used for formation of a three-dimensional terrain map, and also at solving the problems of a relief estimation: calculation of distances, calculation of the areas and volumes, profiling, building the visibility zones, determining directions of slopes.

The "Complex of 3D analysis" uses models of surfaces in the tasks of constructing isolines, formations of H coordinate (height) of map objects, when constructing flood zones and for modeling emergency situations. The "Complex of 3D analysis" also includes the tasks of predicting the area of an emergency oil spill and calculating the volume of earthworks.

The new version of the program is available for download in the Download section.

Specialists of KB "Panorama" have prepared a video lesson of using the "Sorting" mode. From the training material, users will learn about the operation of the tool that arranges the placement of object descriptions in metrics and semantics files. Sorting speeds up further processing of data and ensures the correct sequence of displaying objects. In addition, when sorting, you can exclude the metrics and semantics of deleted objects and copies of edited objects from files. Thus, compression of the data is carried out.

It is recommended to start the data sorting mode after performing any procedures that change the metric or semantic description of vector map objects. Sorting of map objects can change: coordinates precision; kind of stored coordinates; encryption of data. When the "Sorting updated sheets only" mode is enabled, sorting will be performed only for those sheets on which objects were edited. This reduces sorting time. If the "Remove copies of the edited objects" mode is enabled, then after sorting it is impossible to restore the objects removed or edited earlier. This reduces the volume of data on the disk. If the "Generalization of multiscale objects" mode is selected, then for objects of the RSC classifier that have the Multiscale property, additional contours will be built using the generalization method. Sorting allows you to change the format of a vector map.

Multisheet and user maps can be packed into one file with compression of data. The packaged multisheet map has the MAPZ extension, the packaged user map has the SITZ extension. To increase the degree of compression, the precision of the object metrics is automatically converted to centimeters. The volume of the packed data decreases approximately in 3 times in comparison with volume of the initial data with the maximum precision of the metrics. Unpacking of data is carried out in memory in process of reading corresponding sheets and objects. If the map sheet is located in memory entirely it is unpacked in a multi-threaded mode when opening the data of sheet to speed up access. Packed maps are read-only.

You can get acquainted with the training materials in the "Video lessons" section.
