GIS "Operator" provides construction of a highly accurate digital terrain model of a single geoinformation space based on laser scanning data

12.07.2017

In KB "Panorama" the GIS "Operator" of version 12.5.0 for power structures is developed. The program provides support for a single geoinformation space based on building a network architecture managed by spatial data servers (GIS Server) and application servers (GIS WebService SE). As a source of geospatial data the Databank of digital maps and remote sensing data can be applied.

In the new version, the speed of requesting and updating data from the GIS Server has been increased for providing collective work in a network with maps of the terrain and operational situation for the planning and management of troops and weapons. The ruler of sources of the data has been expanded that are used for formation of terrain elevation matrixes and execution of computational tasks related with heights (construction of profiles, visibility zones, estimation of elevation, calculation of ground volumes, 3D modeling).

The task "Navigator 3D" is refined. Into it the new mode "Cloud of points" is added which provides displaying the data of laser scanning of terrain in three-dimensional model. As one of sources of the data of laser scanning, the dense digital model of a surface is used that was created by software PHOTOMOD DenseDSM of the Rakurs company. The model, calculated on the basis of many types of input data using the method SGM (Semi-Global Matching), simplifies the creation of three-dimensional urban high-resolution models and can be loaded into the GIS "Panorama" for displaying in two-dimensional and three-dimensional form, vectoring, constructions of profiles and execution of other calculation tasks. The digital model of a surface comes in LAS-files. The data of the terrain's laser scanning is downloaded from LAS-files and stored as MTD-models.

The new "Cloud of points" mode allows you to display in a three-dimensional form a cloud of points of any volume. If the points have not only high-altitude, but also the color data, this data is also used for 3D-displaying. Otherwise, the model is displayed in the colors of the altitude palette. The model of a cloud of points can be displayed in the original form or its data are included into the terrain mapping.

In the new version of the program the converter of digital vector maps from SHP format has been improved. It supports the import of a folders tree with SHP files, with the automatic formation of sheets and map layers in national division and coordinate systems, with the assignment of conventional symbols by alphanumeric code in any national language encoded in UTF.

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.

The sorting of multi-sheet maps (MAP) is accelerated by 3-4 times due to multi-threaded processing on multi-core processors. When sorting map objects, the order of displaying objects in the layer is taken into account.

The task "Import of navigational data from GPX files" is improved. The program allows to load simultaneously several files in format GPX onto one map. This will save operator time on converting data.

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.

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