Generate raster tiles from QGIS project

Generate zipped raster tiles from an archive with QGIS project and data.

Inputs:

• ZIP file containing QGIS project and data files;

• Extent. If empty, a combined extent of all layers will be used. It may unexpectedly calculate an extent of the entire planet, then the tool will take a lot of time to process. Options to set the extent are: 1) upload a file with polygons - it’s handy if you need tiles for a complex area, along a coastline, for example, 2) mark it on a map, 3) draw it on the map and then correct the numbers or 4) enter the extent manually following the format ‘xmin, xmax, ymin, ymax’. Enter coordinates in WGS 84 (EPSG:4326), for example -7.3,42.1,10.5,50.5;

• Min zoom level - between 0 and 25, the default value is 0;

• Max zoom level - between 0 and 25, the default value is 9;

• Tile image format - if not specified generates PNG tiles. You can also enter JPG;

• Background color in RGBA, if not specified, 0,0,0,0 (transparent) will apply;

• DPI - image resolution in dots per inch, between 48 and 600, the default value is 96;

• Metatile size - between 1 and 20, the default value is 4;

• JPEG quality - the level of image compression between 1 (more compression, low quality) and 100 (max quality), the default is moderately compressed, 75;

• Tile height in pixels, if not specified, 255 will apply;

• Tile width in pixels, if not specified, 255 will apply.

Output:

• ZIP archive with tile images organized into folders.
