In KB "Panorama" the GIS Constructor version 12.3.2 the GIS is developed for operating system MSVS 3.0. The new version adds the ability to build a surface profile along a specified line or selected object using a matrix of heights. The result is displayed in a window as a graph, with help of which the user can interactively determine the elevation parameters at the selected point (profile height, degree of slope). Automatically calculates the elevation's values of current and end points that must be added to ensure line of sight. The building results can be exported to a text or graphic file (bmp, png, jpeg). Import of high-altitude data from the exchange format grd is realized.
The visual component of animation of objects of a vector map is added. It allows you graphically to select an arbitrary set of objects with a given color and periodicity. With this functionality, you can implement an animated representation of the result of a search or the operations of adding, deleting, editing objects. Selection of objects for marking is carried out using standard tools of work with the context of the search from the MAPAPI interface. The animation component can be used in combination with the Qt framework's drawing tools to implement arbitrary dynamic selection of spatial data.
The set of test examples is expanded, including: creating of a matrix of qualities, constructions of a visibility area, import of the height data from the grd format, a changing the coordinates of the metrics of object. The functionality of the basic demonstration example mapview is supplemented by map turn, change of parameters of displaying the spatial data (brightness, contrast, transparency), moving of window to the point and center of the object, displaying the cursor coordinates in the status bar.
In the print component, the functionality of outputting spatial data to a physical printer is realized. There is increased the maximum number of processed search contexts for processing vector maps with a large number of sheets in the search component. The processing of the classifier in the component of the road graph is improved.
GIS Constructor is a set of geoinformation components for use in the visual programming environment of Qt Designer, which allows you to develop your own GIS applications. The visualization of the contents of digital maps is made in conventional symbols adopted for topographic, geographical and various special maps. Geoinformation system has ample opportunities for performing calculations, for providing display of spatial data on various graphic devices in standard and user systems of conventional symbols. The main functions can be executed in multithreaded mode. It supports automatic optimization of used memory for processing large amounts of data (tens of gigabytes) on limited resources (hundreds of megabytes).
The toolkit is adapted to work on a wide range of platforms and supports operating systems such as Astra Linux SE, MSVS, CRTOS Neutrino, Elbrus, Zarya, Ubuntu, Alt Linux, QNX, CentOS and others. It can be used in computer complexes with processors of architectures ARMv7, Elbrus, PowerPC, Intel x86, Intel x64 and others.
The new version of the program is available for download in the
