In KB "Panorama" the ImageryCreator version 9.1 is developed. The new version of the program allows you to create tiles in the SQLite database format - MBTiles. The advantage of this method of storage of tiles compared with storage of tiles in the form of separate files in system consists in saving of a space on a hard disk. All data is stored in a single database file. Tiles in MBTiles format on average take up to 30% less space on the hard disk. The speed of access to the tile in the SQLite database in the Windows system is comparable to the speed of access to the file directly. Use of the MBTiles format will simplify and speed up the process of transferring tiles between servers and hard disks. In order to optimize the use of free space on the hard disk, the program analyzes the size of the created tiles and does not store tiles that do not contain information (empty data). The new version supports the cutting of tiles with numbering for the TMS standard.
The program allows you to create tiles in the formats JPEG, PNG, PNG8 and MBTiles according to the international standard OGC WMTS 07-057r7 version 1.0.0 and the TMS standard. Tile data generated by the ImageryCreator program is used by software of GIS WebServer SE, GIS WebService SE to provide high-speed query execution for displaying spatial data over large areas while simultaneously accessing a large number of users.
The new version of the program is available for download on the Download page.
