In Imagery Creator the speed of tiles formation in Mbtiles format is increased more than in 10 times

10.10.2017

In KB "Panorama" the Imagery Creator version 9.3 is developed. The new version of the program allows you to create a large number of tiles in a minimal amount of time by recording data blocks as separate transactions. The use of this technology will allow to reduce the time for preparation of data for their further use in the programs GIS WebServer SE and GIS WebService SE.

Imagery Creator automatically excludes empty tiles (not containing information) for optimal use of free space on the hard disk. For example, it takes less than 3 minutes to store more than 1 500 000 tiles in the database. Saving the same amount of tiles to disk in the form of files takes about 5 minutes. Use of SQLite has several advantages: on average, tiles take up 30% less space on the hard disk, all data are stored in one file, so the process of transferring tiles between servers and hard disks is simplified and is accelerated in several times.

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. The tile data generated by the Imagery Creator program are used by GIS WebServer SE, GIS WebService SE software 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.
