quant_quality The quality of quantization. jpg_quality The quality of JPEG compression. There are some options to specify parameters of the conversion into image formats, which can significantly reduce size of produced tiles by degrading the output. Default background color is white (255,255,255), but you can specify your own with the option: -bg The color of the background replacing transparency in the non-transparent tile formats. If partly transparent tiles are saved into a tile format without support for transparency (such as JPEG specified with -f jpg option) then the background color is applied. Otherwise the tile is marked as partly transparent with alpha. opaque, maximum alpha is 255), the alpha channel is discarded and the tile is marked as non-transparent / opaque. If all of the pixels are fully visible (eg. If the tile is completely transparent it is never saved to the disk to save the storage space. The transparency can come from the image itself as an alpha channel (with support for partly transparent areas), it can be derived from a selected color (so called NODATA color), or can be just a result of the transformation with the GDAL warping algorithm - for areas without available input data. No matter what input datasets you specify, after transforming them into the tiling profile projection, MapTiler will handle them as RGBA images.

Tile transparency or a background color ¶ kmz and save it into the device.Įxample: command for producing tiles for use with Google Earth: garmin To produce format for Garmin GPS devices, with a size 1024x1024 pixels and output to. raster Rendering raster files without a need of georeference is possible as well. See the appropriate section under the Advanced options chapter for more information. custom You can specify your own tiling system. gearth Tile profile specific for Google Earth according the KML SuperOverlay definition.

Compatible with most existing WMS servers, OpenLayers base map. These are the alternatives: -geodetic WGS84 Plate Caree / Unprojected. In case you wish to use other tiling system, you must specify it as the first command on the command line. To create high-resolution Retina / HiDPI tiles with double pixel resolution. It uses coordinate system defined as EPSG:3857 or EPSG:900913. The spherical mercator tile profile compatible with Google, Bing, Yahoo Maps, MapQuest, OpenStreetMap, and mobile maps on iOS and Android. MapTiler comes with three predefined most popular systems and possibility to specify a custom profile. A global option defining the output system of tiles - the target coordinate system, tile pixel size, etc.
