Databank of digital maps and RSE data - the complex of programs for conducting cloud storage of spatial datasets, collecting and storage of metadata, selection and output of spatial data by request, preparation of reports, formation and publication of geo-covers, mapping status of databank as map-schemes.

Map-schemes are providing for each type of stored data: vector maps, RSE data, height matrices and terrain models. Provides remote placement of spatial data sets in the file storage, conduction editions of the stored sets, updating map-schemes of the availability of data, automated collection and formation of metadata.

The complex of programs includes: Database management system, GIS Server, GIS WebService SE, Databank.

The basis for building the spatial data infrastructure of the federal,regional and municipal levels and in corporate information systems.

Main characteristics

  • Software is implemented for OC Red Hat, Debian, Fedora, QNX, CentOS, MS Windows and other;
  • Compatiable with various means of providing Security (means of authorization, Data encryption, antiviruses, firewalls and other);
  • Support for processors Intel, AMD, SPARC, MIPS, ARM, Elbrus and other;
  • Users interface is implemented in russian, english, french and other languages.

Work scheme of Databank work


Main functions

  • Maintenance of distributed structure of file storehouse, unlimited amounts of stored data;
  • Maintenance of metadata database according to international standards;
  • Visual display of the status of the data bank on the map-schema, search of data by characteristics;
  • Obtaining selected sets of spatial data;
  • Authorization and delimitation of access rights;
  • Remote placement of spatial data into file storehouse;
  • Editing metadata;
  • Creation of geo-covers from stored data sets;
  • Logging of user actions;
  • Formation of reports on the state of the databank and the issuance of materials;
  • Configuring the general settings of application.

File storehouse of data

Maintenance of distributed structure of file storehouse, unlimited amounts of stored data. The data can be on different physical media, the mirroring mode can be used.

Database of metadata

Maintenance of the metadata database by international standards

  • ISO 19115:2003;
  • Geographic information - Metadata and ISO/TS 19139;
  • Geographic information - Metadata - XML schema implementation.

Visual display

Visual display of the status of the data bank on the map-schema, search of data Displaying datasets in tabular form and in the form of maps-schemes.

Search and filtration of data sets by characteristics and spatial position.

Data downloading

Obtaining selected sets of spatial data in the form of a single zip-archive in one request.
Implementation of data selection by spatial filter on the map and by characteristics of metadata.

Authorization and differentiation of access rights

Support of domain authorization (Active Directory, KERBEROS, system authentication of web-server).
Differentiation of access rights.

Data loading

Remote placement of spatial data into file warehouse.
Choice of group at data loading.
Automatic or manual definition of group.
Automatic formation of metadata.
Formation of reduced copies of data images.
Updating maps-schemes of data availability.
Maintenance of versions of stored datasets and the accounting in the metadata database.

Work with metadata

Editing the information and removal of data sets from storehouse.
Expandable list of metadata fields.
Connecting to external information sources.

Geo-coverage

Automated formation and updating of geo-covers.
Selection of data by various criteria:

  • territory,
  • date of terrain survey,
  • scale,
  • type of material,
  • and others.

Work with geo-coverages in various geoinformation systems.

Logging of user actions

Conducting and viewing the log of of users actions.

GIS WebAdministrator

Configuring the general settings of the application's work.
Configuring the metadata database settings.
The choice of storage formats and the composition of groups of stored files.
Selecting the views of objects on the map-schemes.
Conducting groups of users and differentiation of access rights.

Reports

Formation of reports on the state of the databank and the issuance of materials.

  • by data types;
  • by scales;
  • by the terrain state.
