Panorama-Editor implements an advanced technology for creating and automated generalisation of topographic maps

20.12.2018

In KB "Panorama" the professional vectorizer "Panorama-Editor" version 12.6.3 for x64 platform is developed. In the new version into the task "Automated generalization of topographical maps" the new modes "Setting the boundaries of rivers visibility" and "Quarters generalisation" are added.

The mode "Setting the boundaries of rivers visibility" is intended for simplification of a hydrographic network in the map scales 50 000 and 100 000. The goal of simplifying the hydrographic network is to assign specific ranges of visibility to specific objects of the hydrographic network, corresponding to their importance. Degree of the rivers importance is defined by the length and character of its location relative to other rivers. As a result of the implementation of the "Quarters generalisation" mode the automatic uniting of closely located same-type quarters and adjustment of quarters with linear objects of the road network is performed. When adjusting the quarters, the quarters are cut by streets and passages, taking into account the width of linear objects. The software "Automated generalization of topographical maps" is used to convert a map of the source scale into a map of a smaller scale (derived scale).

The new task “Creation of passages in settlement” has been developed. The task is intended to create on the map additional linear objects that are passages in settlements. Passages are created between the adjacent quarters and the sides of the streets. The task performs the adjusting of created passages with each other, and also with road network objects available on a map. Construction of passages allows you to automate the creation of navigation maps, as well as to prepare maps for the implementation of generalization of the road network and settlements in the mapping of smaller scales.

Into the "View Passport" task there is added a new type of maps "Topographic PZ-90.11" (Pulkovo2017), based on application of the PZ-90.11 ellipsoid and the Gauss-Krueger projection. As a system of heights, the World Ocean Level (Geoid) is set that is corresponding to the EGM2008 model.

The task of Creation of rule adds support for a new type of map. To speed up work with large regions (MAP maps containing more than 1000 sheets), when you import sheet lists into DIR, folders for every 1000 sheets are automatically created starting with the second one. The folders are named sheets_1000 (for sheets from 1000 to 1999), sheets_2000 (for sheets from 2000 to 2999), etc. The first thousand sheets are written in a folder together with the passport of the region map. For every 1000 sheets, 4-5 thousand files are created. Earlier versions of programs open such regions in the usual way, if they are from the same OS (MS Windows or Linux) with the program that created the large region.

The task "Map Editor" is improved, the mode "Building the azimuth circle" is added. The azimuth circle is a set of closed circles of a preset radius and the straight lines divergent in all directions in accordance with specified indicators of angles. Values of radiuses and angles of the azimuth circle are drawn onto the map in the form of explanatory labels. The parameters of lines and labels can be set by the user when building the azimuth circle.

In the "Map Editor" task, into the "Autofigures" group, a new object creation mode was added - "Create expanding zone". Expanding zone is an area around a part of a linear object whose radius is evenly increased from zero to the value specified in the Map Editor parameters. Expanding zone can be used to display on the transport maps the ways of servicing the trains on the sections of circulation of locomotives and locomotive brigades.

A support of SQLite database for pyramids of tiles in Mbtiles format is added. Mbtiles format is convenient for storing tile data, since it consists of a single file.

Satellite images in TIFF format can contain dozens of gigabytes of information, so they are slowly displayed. To speed up the display and preserve the quality of the data, they are converted to the Mbtiles format. You can convert data into Mbtiles format using the Imagery Creator program.

The task of connecting geoportals is improved. Support of Flightradar24 geoportal is added for monitoring aircraft movement. A new geoportal of regional geographic information system of the Moscow Region (RGIS)" has been added. Information about spatial objects is placed in the system by the responsible state authorities and local self-government bodies of the Moscow Region and is the official state information resource of the Moscow Region. Support for geoportals with an arbitrary tile size is added. The settings are put into the user file crsregister.xml, which contains the description of user matrixes, their projections, scale factors and tile sizes. Speed of displaying geoportals is increased. Possibility of imposing the color filter on the image of a geoportal is added. It allows you to change color of lines, areas, titles onto the color of filter. For example, to change the color of quarters from red to blue on the Rosreestr geoportal. The ability to set the offset for different geoportals is added. This option is necessary to set an exact match between the source data and the geoportal, which artificially introduces an offset.

There is implemented a display of rasters and matrixes with recalculation of coordinate systems (transformation) and/or turning on the fly. This allows you to display images and matrixes of elevations together with geoportals and vector maps with different coordinate systems and rotate these images at an arbitrary angle (for example, in a navigation task). The display speed of rasters and matrixes with transformation and rotation roughly corresponds to the usual display of rasters due to the use of multi-thread processing for multi-core processors and new data caching algorithms (display processes are accelerated 10 or more times).

The new mode of creating a multipolygon by selected polygon objects is added.

Tools of combining objects into sets (logical groups) on the map are improved. Sets of objects are formed by addition to objects of attributes with number of objects set and type (the objects equal in rights, the main/subordinated object).
