Data bank of digital maps and remote sensing data for Astra Linux SE increases the level of automation of processing metadata when large amounts of data are placed in cloud storage

29.10.2018

In KB "Panorama" the Databank of digital maps and remote sensing data version 3.8.3 was developed for OS Astra Linux SE (Release "Smolensk"). In the new version, the mode of setting values of metadata is added when large amounts of data sets are loaded into the cloud storage. This allows you to set the same values, for example, the date of of survey, security classification, or the comment, for all the data currently being loaded. To support a large number of records (more than 1 million), the table of metadata has been further improved. Existing metadata can be effectively changed by means of new possibility of group editing.

The list of groups of processed data is supplemented by classifiers. Classifier metadata includes information about the date of classifier creation, manufacturer, size, a link onto the protocol of placing into the storage. The user gets the opportunity to maintain his own catalog of classifiers with automatic versioning.

The process of transferring existing spatial data sets from one Databank to another has been simplified. To this end, new modes of export and import have been added, allowing to upload data together with metadata. There is added the uploading the list of selected data sets into a file of XLS and DOC format.

In the program the possibility of control of data integrity is implemented. This mode, in addition to restoring the map-scheme, makes comparison of data sets being in the cloud storage with their backups, if it detects differences in the files, restores them.

Within the framework of a single geoinformation space, the Data Bank of digital maps and remote sensing data implements the collection, storage, search and issuance of 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 storage 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 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.
