Data bank of Digital Maps and Remote Sensing provides a one-time placement into the data warehouse of a large number of maps and images

10.07.2017

In KB "Panorama" the Databank of digital maps and Remote Sensing Data of version 3.5 is developed. The new version optimizes the loading of a large number of materials into the data warehouse. There is added a mode of placing into the data warehouse without downloading via the HTTP protocol, the data is downloaded from the local folder. Two download modes are supported: remote downloading of data sets via HTTP protocol and download over the local network from the available device. Downloading over the local network provides a one-time placing of a large amount of data into the data warehouse and a higher filling rate of the Data Bank.

Security is increased when working with the database, work with the database is implemented through a separate account with limited rights.The rights to access the data and functionality of the complex are assigned to users in accordance with the rights of the groups to which they belong. There is expanded the list of metadata fields for maps and remote sensing data, which are automatically filled when materials are placed into the data warehouse. The mode of search and selection of materials is optimized, the ability to manage the list of displayed fields is added to the search tools. The system of the help on work with a complex is realized.

The data bank of digital maps and remote sensing data is intended for building a cloud data warehouse of spatial data, providing access to these data, the automated generation and updating of geo-covers. Provides gathering, storage, search and delivery of spatial data in exchange formats, displaying a 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 heights and terrain models. It provides remote placement of sets of spatial data into file data warehouse, conducting versions of stored sets, update of data availability maps-schemes, the automated collection and formation of metadata, automated formation and updating of geo-covers. Automated collection and formation of metadata is performed according to the standards of ISO 19115: 2003, Geographic information - Metadata and ISO/TS 19139, Geographic information - Metadata - XML schema implementation. The reduced copies of data images are automatically formed, the checksum of files and completeness of data sets are verified.

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 protected data is carried out. The databank includes applications the GIS Server and GIS WebService SE that are certified to Level 2 of undeclared possibilities in system of certification of means of the information protection of the Ministry of Defence of the Russian Federation. For conducting base of the metadata there are used the DBMS PostgreSQL (OS Windows, Astra Linux SE), DBMS Zarya (OS Zarya-data processing center).

The complex includes the module of administrating the Bank of Digital Maps and Remote Sensing Data. It provides customizing the general parameters of the application's work, customizing the parameters of metadata base, a choice of formats of storage and the composition of groups of stored files, types of objects for maps-schemes, conducting the groups of users and assigning the rights of users for access to the data and allowed actions. Users of desktop programs the GIS "Panorama", "Panorama-editor" and others can connect to Bank of metadata through the GIS Server for work.

The new version of the program is available for download on the Download page.
