Databank of Digital Maps and Remote Sensing Data for Linux provides construction of geo-coverings from stored data sets

18.08.2016

In KB Panorama the Databank of Digital Maps and Remote Sensing Data of version 2.4 is developed is developed for Astra Linux Special Edition operating system. In the new version the mode of creation of geo-coverings from stored data sets is implemented. The mode allows to select data sets by various criteria (territory, date of terrain shooting, scale, type of a material and others) and to form coverings from vector maps, rasters or matrixes in the chosen coordinate system. Procedure of forming a geo-covering is carried out on the GIS Server by the command of the Databank operator. For placing the created geo-coverings the virtual folders of GIS Server are used.

It provides automatic access to them without additional administration of various groups of users. For convenience of conducting versions of geo-coverings in the specified virtual folder the separate folders for each covering automatically are created.

Configuring of virtual folders for placing geo-coverings is carried out by the Administrator of Databank of Digital Maps and Remote Sensing Data for each group of the data. Coordinate system of a covering can be specified by EPSG code (for example, "epsg:3857") or by a code of the user's coordinate system (for example, crslist:user_code). In this case the coordinate system parameters are read on the server from the service file by the specified code of user's coordinate system (identifier). Parameters of the user's coordinate system can be added onto the GIS Server from the task "Map Passport" of system the GIS "Panorama". Upon termination of procedure of forming the geo-covering the work protocol is created. Data sets of geo-coverings are recorded in database of metadata and displayed on a map-scheme. Objects of geo-coverings of different groups of the data have different color filling on the scheme. During formation of geo-coverings the survey image also is created.

Databank of digital maps and remote sensing data is intended for gathering, storage, search, issuance of spatial data in exchange formats and displaying the status of a databank in the form of maps-schemes. Maps-schemes are conducted for each type of stored data: vector maps, remote sensing data, matrixes of elevations and terrain models. The reference to the Databank and data exchange is carried out via the web-interface. The program can work in operating systems with the closed contour where processing of the protected data is carried out. The databank includes applications the GIS Server and GIS WebService SE that are certified by Level 2 of absence of undeclared possibilities in system of certifying securities of information of the Ministry of Defence of the Russian Federation. For conducting the base of metadata there are used the DBMS PostgreSQL (OS Astra Linux SE), DBMS Zarya (OS Zarya Data Processing Center).

The module of administration of the Databank of Digital Maps and Remote Sensing Data is included into the Complex. It provides customizing the general parameters of the application's work, a customizing the parameters of metadata database, a choosing the formats of storage and the composition of groups of stored files, views of objects for maps-schemes, a conducting the groups of users and appointment of the users rights onto access to the data and allowed actions. Users of desktop programs of GIS "Panorama", "Panorama-editor" and others can connect to the Bank of metadata via the GIS Server.

Source codes of modules of loading the sets of spatial data and metadata into the Databank of Digital Maps and Remote Sensing Data are included into SDK for the GIS Server and GIS WebService SE. Using SDK it is possible to expand operations on conducting archive of spatial data from other applications.

New versions of software and documentation are available on the Download page.
