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 Engine will handle them as RGBA images. Tile transparency or a background color ¶ See the appropriate section under the Advanced options chapter for more information.Įxample: command for producing tiles for use with Google Earth: custom You can specify your own tiling system. garmin To produce the format for Garmin GPS devices, with a size 1024x1024 pixels and output to. raster Rendering raster files without a need of georeferencing is also possible. These are the alternatives: -gearth Tile profile specific for Google Earth according to the KML SuperOverlay definition. In case you wish to use different tiling system, you must specify it as the first command on the command line. 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 Engine comes with these 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.
