Databank of digital maps and Earth's Remote Sensing supports the exchange of metadata between the different organisations

13.10.2017

In KB "Panorama" the Databank of digital maps and ERS version 3.7 is developed. The new version adds the functions of importing and exporting metadata in XML format. This makes it possible to organize a centralized repository of spatial data and metadata in one organization, while other organizations transmit only metadata. Such a mechanism is necessary when it is not possible to organize direct access to the data bank on information security requirements and in other cases.

The metadata contains complete information about the stored data sets, including information about the territory, the date of the terrain condition, the accuracy, the coordinate system, the data format, the organization storing the source materials.

After receiving the metadata, they are imported into the complex of Data bank of digital maps and Earth's Remote Sensing (ERS). It allows to use all means of searching for sets of spatial data, to form requests on their obtaining from the centralised storehouse, to print reports and inquiries, to carry out scheduling on gathering and processing the data.

Within the framework of a single geoinformation space, the Data Bank of digital maps and remote sensing data realises gathering, storage, search and delivery of the spatial data in exchange formats. The spatial data selected by means of the program can be placed for the multiuser access on the GIS Server and be published according to the international standards OGC WFS, WFS-T, WMS, WMTS, WCS on application server the GIS WebService SE. Users can access data from both a thin client (by means of GIS WebServer SE) and from desktop applications (GIS "Panorama", GIS "Operator").

The databank of digital maps and ERS data provides construction of cloud storehouse of spatial data, provision of access to these data, the automated formation and updating of geo-covers. The current state of spatial data is displayed by means of maps-schemes that are maintained for each type of stored data: vector maps, remote sensing data, elevation matrices and terrain models. It provides remote placing the sets of spatial data into file storehouse, keeping versions of stored sets, updating maps-schemes of data availability, the automated collection and formation of metadata, and the 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, checksum of files and completeness of data sets are checked.

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