Data bank of digital maps and remote sensing for CentOS OS increases the speed of loading spatial data into the cloud repository

01.08.2017

In KB "Panorama" the Databank of digital maps and remote sensing data of version 3.5 is developed for CentOS. The new version adds the ability to load spatial data into the repository directly from the local directory. This allows you to increase the speed of data placement by not having to use the HTTP protocol for transfer.The user is able to simultaneously download a large amount of data in a short period of time.

Security is increased when working with the database by using a separate account with limited rights. The rights to access 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.

Within the framework of a single geoinformation space, the Data Bank of digital maps and remote sensing data collects, stores, searches for and provides spatial data in exchange formats. The spatial data selected with the help of the Data Bank can be placed for multiuser access on the GIS Server and published according to the international standards OGC WFS, WFS-T, WMS, WMTS, WCS on the GIS WebService SE application server. Users can access data from both a thin client (using the GIS WebServer SE) and from desktop applications (GIS Panorama, GIS Operator).

The database of digital maps and remote sensing data provides the construction of a cloud repository of spatial data, the provision of access to these data, the automated formation and updating of geo-covers. The current state of the spatial data is displayed by means of maps-schemes that are maintained 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 storage, a keeping the versions of stored sets, an updating of 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, the checksum of files and completeness of data sets are checked.

The new version of the program is available for download in the Download section.
