Automatic intelligent update of spatial data (tiles)

At transfer and an exchange of the spatial data the size of the data for updating or query can total tens or hundreds of gigabytes of spatial information. In most cases there is no necessity to obtain all this data, sufficiently only their part onto certain territory, depending on division level (state, federal, municipal, enterprise level).

Formation and filling of BSD by the tile data requires more time, and computing operations. But what about the ever-changing data? Of course for this purpose it is possible to assign the operators, who would monitor the change of vector, matrix or raster data, but that if the volume of this data is estimated in hundreds information gigabytes, or only the part of them is changed and specified - to keep track of changing all parameters to the simple operator it is impossible, and process of new reorganization of a tile base is long. Therefore acutely a question arises about automation of this process. For this purpose, there was been developed a service of Panorama Imagery Service, which is an automated intelligent system (AIS) to maintain tile base of BSD in an actual condition.
