GIS Constructor extends the possibilities of creating GIS-applications by using the cross-platform Qt 5 framework


In KB "Panorama" the GIS Constructor of version 12.0.3 is developed for operating system Astra Linux Special Edition (release "Smolensk"). The new version is adapted to work with the Qt framework version 5.5. This enables developers to create modern user interfaces with use of Qt QML and Qt Quick modules in combination with high-speed digital data access logic implemented on the basis of C ++ and the MAPAPI interface. By using the combination of Qt Location module for obtaining geographical coordinates and access interfaces to digital data the GIS Constructor extends a set of data sources for creating and updating maps.

The source texts of GIS applications written with using the software product the GIS Constructor and Qt framework are cross-platform and can be used for assembly for a wide range of devices: desktop, mobile and embedded. Adaptation of existing GIS applications for work with new versions of GIS Constructor and Qt require a minimum of efforts due to preserving the interfaces of the graphic components of the GIS Constructor and the interface for accessing digital MAPAPI data. The graphical components of the program are adapted for use with the new version of the environment for the development of graphical interfaces of Qt Designer.

GIS Constructor implements support for a single geoinformation space managed by spatial data servers (GIS Server) and application servers (GIS WebService SE). Due to the ability to work with the GIS Server, users of GIS applications can directly connect to geospatial data bases, view and edit tables in the form of maps in the specified conventional symbols. Support for interaction with GIS WebService SE allows to get access to spatial data according to international standards OGC WFS, WFS-T, WMS, WMTS, WCS.

GIS Constructor supports various coordinate systems and projections, provides ample opportunities for creating and adding of user conventional symbols. Visualization of the contents of digital maps is made in conventional symbols adopted for topographic, geographic, cadastral and other types of maps.

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