GIS Server simplifies the publication of spatial data bases within information systems


In KB "Panorama" the GIS Server version 7.4 is developed. In the new version the tools for publication of the information from the spatial databases operated by DBMS Oracle, PostgreSQL, MS SQL and others are refined. Possibility is added to set conventional symbols of database objects by the alphanumeric code stored in a separate field of the database table. The alphanumeric code is an analog of the classification integer code and is also used to encode conventional symbols of objects. In the Classifier Editor of the GIS "Panorama" the possibility is available to enter not only digital codes, but also arbitrary strings in national languages (alphanumeric code). Its main destination is the specifying a mutual conformity of conventional symbols of objects on digital maps and combinations of values of objects attributes, including a code, in databases and other sources of the information. When connecting to a database, the GIS Server has the ability to define a coordinate system in which the spatial description of objects in the database is stored. If the coordinate system and projection parameters specified by the application's settings for displaying the cartographic representation coincide with the parameters of storing of spatial data in the database, the GIS Server does not perform additional operations for transformation of coordinates. If the parameters of the projection and the coordinate system for storing of spatial data in the database differ from the established parameters for cartographical representation of this data on the GIS Server, the transformation of the spatial description of the objects in the database is performed by the DBMS tools directly into the coordinate system of the cartographic representation. Previously, such recalculations were carried out in two stages: at first, the coordinates were converted from the original system to WGS84, and then from WGS84 to the target coordinate system. The coordinate system and projection parameters for both information in the database and for its cartographic representation on the GIS Server are determined by the EPSG code. Such approach accelerates the publication of spatial databases of great volumes.

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