GIS Server expands tools of creating and displaying databases of spatial data for various purposes


In KB "Panorama" the GIS Server version 7.4.3 is developed. The new version provides complete management of spatial databases of arbitrary structure. There is implemented a direct editing of databases records with fields of different types, containing the coordinates of objects. Fields of spatial description of objects are supported for DBMS of Oracle, and PostgreSQL is SDO_GEOMETRY, St_Geometry ArcSDE, St_Geometry PostGIS. Database connection parameters, coordinate system code, library of conventional symbols and table fields assignment are customized by the GIS Server Administrator. For compensation of absence of some information layers and some attributes in a database (titles, kilometer grids, filling signs, undirected point signs - bridges, buildings and so on) in the GIS "Panorama" are implemented an automatic procedures on arrangement of titles, formation of grids, a turn of signs and others. It provides editing of data in multi-user mode with high intensity, including support for applications that transmit data in automatic mode. On the client's monitor, the map will have the same appearance and be edited by the same tools, regardless of how the data is stored on the server-in data sets or in a database. The assembly of information by layers stored in various tables (one cover can be collected from more than a hundred tables) is performed automatically at the time of access to the data. Different layers can be located in different bases and in data sets as part of general image of the territory.

GIS Server automates the creation of backup sets of data in the Databank of digital maps and remote sensing data, control of integrity of data sets and their recovery. Automatic creating one or two backup copies of downloadable into the Databank of data sets with distributed storage of backups for different data groups is performed. In procedure of control of the databank metadata a check of backup copies availability in accordance with the group settings is added. In the absence of the first or second backup copies the automatic formation of a copy of the main data set and auxiliary files (classifiers, metadata, images, etc.) is carried out. Automatic recovery of data sets is ensured if there are two identical backup copies in the Data Bank of Digital Maps and Remote Sensing Data.

The possibility is added for transferring the arbitrary (user) metadata for data sets loaded into the Data Bank of Digital Maps and Remote Sensing Data directly in the list of xml format sets. In the list of downloadable sets, you can specify metadata for both the entire data list and for each set individually.

The network-centric architecture of storing and processing data is realized due to the distribution of data storage functions and the provision of access to them onto a group of servers united into the network, with automatic duplication and replication of transmitted information, with the ability to function in the event of failure of individual servers by readdressing requests and issuing a copy of data stored on an inaccessible server. Replication of information is carried out in the minimum necessary volume: the description of only updated (coordinates or attributes) or created objects is transferred. GIS Server is intended to provide remote access to the spatial data for users of programs the GIS "Panorama", GIS "Operator", GIS WebService SE and others. GIS Server is certified in the information security system.

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