Tool for creating tiles from QGIS projects.

This plugin was developed by NextGIS for the UNDP/GEF «Разработка для пилотных заповедников системы контроля территории, основанной на базовых интерактивных картах в среде ГИС (обеспечение мониторинговых работ и патрулирования)».

Plugin goal — creating multilevel tile cache according to the Slippy Map specification that can be loaded into mobile devices.

main window will appear

Plugin main window

"Output" group is used to select output type: as directory structure or as ZIP-archive.

Group «Extent» allow to set desired geographic extent of the map. You can select one of the following options:

  • Canvas extent — current canvas extent will be used
  • Full extent — full extent of all project layers will be used
  • Layer extent — output extent will be the same as extent of the selected layer

In «Zoom» group one can set zoom levels. In most cases maximum zoom 18 is enough, but plugin can generate tiles for "deeper" zoom levels. "Depth" depends on the map detalization on certain scales.

"Parameters" group is used to define tile size. Supported values are 128 - 2048 pixels per side.

Press "ОК" to start tile generation and "Cancel" to terminate it.
