Databank of digital maps and remote sensing data provides automatic backup and control of the integrity of spatial data


In KB "Panorama" the Databank of digital maps and Remote Sensing Data version 3.8.7 is developed. In the new version automatic creating a backup of metadata database is added when placing new spatial data into data warehouse. The backup is created taking into account the backup's interval settings. Possibility of creating a backup copy in a manual mode is supported.

For each data type, two backup storage locations can be defined at once. When performing the data integrity control procedure, the data stored in the data warehouse is compared with their backup copies. If there are differences in the files, they are restored. A section has been added to the documentation describing how to set up backups in automatic and manual modes.

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 remote sensing data provides construction of cloud warehouse 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 matrixes and terrain models. It provides remote placing the sets of spatial data into file warehouse, 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.
