GIS "Operator" provides monitoring of mobile objects in a three-dimensional model according to data of satellite navigation systems GLONASS and GPS

20.02.2019

In KB "Panorama" the GIS "Operator" version 12.7 is developed for the x64 platform. In the new version in the "Navigator 3D" task, support has been added for displaying data in a volumetric form from geoportals for monitoring vehicle movement, weather changes or other dynamic phenomena. Data acquisition is performed by connecting web-services using the WFS protocol. In this case, you can find out the current information about a moving object: exact coordinates, current speed, height (depth) of movement, workload, remaining amount of fuel and other data that an object can give about itself. All this is placed into its metric and semantic characteristics and is given to the operator in a dialog when selecting the object of interest. The period of updating information depends on the frequency with which the object displays information, and on the settings of the Update period specified in the Options menu. For example, from the Flightradar24 geoportal, you can track the position of an aircraft if it is equipped with an ADS-B type transponder, which every second generates and broadcasts a radio message that contains exact coordinates, speed, altitude and other information about the aircraft. The service uses ADS-B receivers installed all over the world, which receive information from airplanes and send it to the Flightradar24 server. There are improved the tools of importing models of formats Collada, TLS, OC3 to the database of three-dimensional DB3D tiles in the mode of adding and updating models in the database.

The task "To locate photos of JPEG on map by GPS-coordinates", designed to automatically link JPEG photos to the map, has been improved. The list of formats of processed source data in the "preliminary compilation" mode has been expanded. Loading the project of data of shooting from the UAV is added. The project of shooting's data is a set of JPEG files plus a text file — a list of JPEG photos and GPS-coordinates of points of photographing that correspond to them. The "preliminary compilation" mode allows you to process shooting materials obtained from the UAV. An automatic binding and turn of the photo image by coordinates of the shooting point and the direction angle of the image is carried out.

Possibility of obtaining and displaying the packed pyramids of tiles from the GIS Server is added. Data can be in BIR, Mbtiles formats, stored in a database managed by SQLite DBMS. Pyramids of tiles can be created in the Imagery Creator program, including in the environment of the Databank of digital maps and remote sensing data, using vector maps, remote sensing data and matrixes of heights of relief and terrain objects. Access to tiles pyramids can be offline without the use of server applications, as well as in client-server mode through GIS WebService SE via the OGC WMTS protocol or through the GIS Server version 8.3 and higher. When accessing client-server mode, the tiles that were accessed are automatically cached on the client's computer, similar to working through a web browser.

Import of a set of files of format S57 (000, 030, 031) from the folder containing the subfolders with the sea map files is implemented. The processing of the S57 format has been accelerated in several times due to the multi-threaded processing of data sets on multi-core processors. The output map can be created in the MAP format (multi-sheet map) or as a set of maps of the formats SIT, SITX as part of the MPT project.

Ability is added for calculating the absolute height at a given point, taking into account the data of nautical charts of IHO S57/S52 standards. When calculating the height, the data of isobaths, depth marks, coastlines and height-level objects are used. There are used the values of semantic characteristics the "Isobath value", "Height above sea level", and also the values from 3D metrics of depth marks. The function of calculating the absolute height according to data of the vector map is used in the "Map Computer" task, as well as in the Complex of hydrological tasks and the Complex of 3D analysis.

Into dialog of search and mark of map objects into the "Measurement" bookmark the possibility is added to set a condition of selecting objects by number of points in the main contour of object. For example, if you need to mark polygons having the shape of a rectangle (4 corners), you can search for a metric of 5 points (the first and the last are the same).

The task of connecting geoportals is improved. Ability is added for displaying geoportals beyond 180 and -180 degrees in longitude for all supported standards. It allows you to display more visually the data on territory of Chukotski Peninsula and Alaska, and also to carry out editing of objects in these territories. Setting sizes of displaying is done via the "Configure geoportals" menu item. By default, the display area of geoportals is set from -225 to 225 degrees.

A call of the "Transparent color" mode has been added to the "Data list" dialog. The mode is designed to disable the display of both one and a group of colors from a palette of 16, 256-color rasters. For 24 bit rasters, a disabling of displaying one color is carried out. The new mode is called on the "Rasters" bookmark by the item of the contextual menu "Transparent color".

In the dialogs of recalculating and displaying the coordinates of the current point on the map, the replacement of the coordinate system PZ-90.02 by PZ-90.11 is performed.

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