GIS Panorama Mini provides high speed of display and processing of remote sensing data (Earth's remote sensing)

14.12.2018

In KB "Panorama" the GIS Panorama Mini version 12.6.3 for the x64 platform is developed. In the new version of the program a support of SQLite database for pyramids of tiles in Mbtiles format is added. You can open the data from the main menu the File - Open. 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.

Support of new data formats MAPZ and SITZ is added. Multi-sheet map and user map can be packed into one file with data compression. Packed multi-sheet map has a MAPZ extension, a packaged user map - SITZ. To increase the degree of compression, the accuracy of the object metric is automatically converted to centimeters. The volume of the packed data decreases approximately in 3 times in comparison with volume of initial data with the maximum accuracy of a metric. Unpacking of data is carried out automatically in memory in process of reading the corresponding sheets and objects from the packed formats. If the map sheet is located in memory entirely it is unpacked in a multithreaded mode at opening of sheet's data for access acceleration. The packed maps are accessible read-only. Conversion to SITZ and MAPZ format is performed in the "Map Sorting" task. Formats SITX, SITZ, MAPZ can be converted back to the original SIT or MAP formats by sorting. Packed maps with the reverse converting retain the accuracy of the metric in centimeters.

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).

New features are added when processing rasters opened directly without conversion to RSW (when opening, the mode "Don't copy the source image to the RSW-file" is selected). There are added a joint discovery and display of Landsat, Kompsat and GeoEye images delivered as a set of single-channel TIF rasters. Single channel TIF rasters are interpreted as different channels of the same image. To speed up the display of raster data, there is added a choice of an arbitrary scheme of created general images: 1: 4, 1:16, 1:64, and others. If the source image contains general images, then they are used directly when creating the derived general images and displaying them. Now you can create compressed general images. The restriction on the maximum size of general images of 4 GB has been removed, which allows processing images of any size. The GDAL library has been updated to version 2.2.0, in which new formats of processed rasters have been added.

The task of connecting geoportals is improved. A new geoportal the "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. Information on health care, education and sports facilities, the MFC, employment centers, as well as information on the approved master plans and land use and development rules are posted on the RGIS geoportal in public access. 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. 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.

The task "GPS\GLONASS Monitor" has been improved. A function is added for determining the location by the data from the navigation receiver without configuring a virtual COM or USB port.The new mechanism of exchanging the navigation data is implemented using the Sensor and Location platform technology and it can operate under the control of the MS Windows 7 operating system and later.

GIS help system updated. Always up-to-date version of the program's help system is located on the server. Help sections are organized in the form of HTML files that are displayed in a regular browser. The opening of help topics from the server has been added in the GIS. In case there is no access to the Internet, it is still possible to use the help system located in the local folder of the computer when installing the program. For a choice of used help system into section "Help" of the main menu of the program the item "Local help" is added. For more information on the program into the Help menu, the items of the Documentation, the Forum and Video lessons are added. The Documentation menu item allows you to view any document from the operational documentation, which speeds up the search for the necessary reference information. Forum item performs a quick transition in the browser to the web forum, designed for communication and information exchange between users and developers of the program. The menu item "Video lessons" is designed for fast transition in the browser to a page of educational films. For the purposes of distance learning, the site contains a number of educational films aimed at mastering the basic technologies and functions of GIS.

For quick opening of examples of maps, rasters and matrixes from the composition of the installation, the "Data examples" item was added to the File menu.

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