Specialists of KB "Panorama" have updated the training material on preparation and execution of the automated generalization of topographic maps. The training material demonstrates a technology of generalization of digital topographic maps by using the task "Automated generalization of topographical maps", which is part of the professional GIS "Panorama". The work of the modes "Formation of nomenclature sheet of a map of derivative scale", "Generalization of hydrography and hydraulic structures", "Generalization of settlements", "Isolines generalization", "Setting of visibility boundaries" is shown.

Into presentation the information about the necessary preparatory work before performing the generalization, requirements to the initial data has been added, and also the processes for the phased execution of the task are considered.

The automated generalization includes automatic modes of data processing which are displayed in the work of the task "Map processing by scenario" and "Automatic labels alignment". The purpose of generalization is to improve the image of the map on a smaller scale, to submit the main features of objects, their characteristic features and relationships. Insignificant or unnecessary for a map of the given destination the information on represented object in the process of generalization is excluded.

You can get acquainted with educational materials in the "Presentation" section.

In KB "Panorama" the classifier of large-scale plans of a scale of 1:5 000 map5000m.rsc, used for publishing maps of regions of the Russian Federation and foreign countries according to OpenStreetMap data, has been improved. There is implemented a support for a multi-level tree of layers for a more convenient search for objects, change of map content, analysis of terrain and updating of digital models of territories. The generalised layers of top level include classes (layers of lower level) of objects by their general properties. For example, the "Vegetation" layer is divided into classes: "Tree and shrub vegetation of natural origin", "Tree and shrub vegetation of artificial origin", "Herbaceous, shrubby, moss vegetation", "Individual trees and characteristics", "Clearings, forest quarters, contour of vegetation", "Agricultural land". Each class can contain objects of different localization - polygons, contours, point symbols, titles. The composition of the classes and the number of the tree levels are selected based on the complexity of the described subject area and maintaining the ease of navigation through the tree of layers. For other classifiers (for example, geological ones), the hierarchy of layers can have a large number of nesting levels. The map5000m.rsc digital classifier and its detailed description are given in the Classifiers section.

On the geoportal "Bank of spatial data", the maps of the region of the Volga Federal District, formed according to OpenStreetMap data using an updated classifier, were updated. The maps included the Kirov, Nizhny Novgorod, Orenburg, Penza, Samara, Saratov regions, the Republic of Bashkortostan, the Republic of Mari El, the Republic of Mordovia, the Republic of Tatarstan, the Udmurt Republic and the Perm Territory. To work with maps, you can use the GIS Panorama Mini program or other software products of KB "Panorama".

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

Specialists of KB "Panorama" have updated a video lesson on filling in information in the "Base of cadastral works" dialog. Users of "Workstation of cadastral engineer", GIS "Panorama" or "Panorama-editor" can add, edit, delete information in the database of cadastral works using a complex of geodesy calculations.

The subsystem "Base of cadastral works" is designed to maintain information about cadastral engineers, customers, measuring instruments, geodetic bases and contracts for the performance of cadastral works. The subsystem is integrated into all modes of preparation of cadastral documents, including: land survey plan, technical plan, map (plan) of object of land management. The information specified in the subsystem dialogs is used to speed up data entry in various modes of forming cadastral documents.

"Base of cadastral works" is stored in the SQLite format and contains information about contracts for the performance of works, cadastral engineers, customers of cadastral works and other information. You can get acquainted with the training materials in the "Video lessons" section.

Specialists of KB "Panorama" have prepared and posted on the geoportal "Bank of spatial data" a map of the Republic of North Macedonia. The map is formed according to OpenStreetMap data. 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 the SITZ format. Placement 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 GIS Panorama Mini version 14.2.6 has been developed for operating systems "Astra Linux Special Edition", "Alt Linux", "RED OS" and GIS Panorama Mini version 14.5.6 for MS Windows. In the new version the saving of a set of open spatial data into pyramids of tiles of the Mbtiles format according to the selected scale range has been implemented. To create pyramids of tiles, a combination of digital vector maps, space and aerial photography, matrixes of heights, data from geoportals (for example, Yandex or OpenStreetMap), as well as other data sources can be used. It is possible to create a pyramid of tiles using other Mbtiles databases by specifying a data fragment on the source image for saving. The Mbtiles format is a SQLite database that stores images in png, jpg, png8 formats. Pyramids of tiles can be published via the OGC WMTS protocol by the GIS WebService SE service or displayed in programs the GIS "Operator", GIS "Panorama", GIS Panorama Mini and in various mobile applications. The purpose of forming a set of rasters (tiles) is to accelerate the display in WEB and mobile applications of spatial data containing a large number of objects or occupying large amounts of data. The Mbtiles pyramid is formed in the EPSG:3857 coordinate system with the TMS pyramid type. You can create tiles using the menu File - Export to a tile pyramid - Mbtiles pyramid.

GIS "Panorama Mini" is the universal geoinformation system designed to collect spatial data, maintain a database of spatial data, create and update digital maps and plans, and create information systems for various purposes. The GIS is included in the Unified register of Russian programs for electronic computers and databases (registry entry No.7226 dated 11/03/2020).

New versions of the programs are available for download on the Download page.
