First, for both file types, it will append 2x to the URL on high-DPI devices. MapLibre SDKs will use the value of the sprite property in the style to generate the URLs for loading both files. stretchY: Same as stretchX, but for the vertical dimension.stretchX: An array of two-element arrays, consisting of two numbers that represent the from position and the to position of areas that can be stretched.If present, and if the icon uses icon -text -fit, the symbol's text will be fit inside the content box. content: An array of four numbers, with the first two specifying the left, top corner, and the last two specifying the right, bottom corner.Image files, which are PNG images containing the sprite data.Īpart from the required width, height, x, and y properties, the following optional properties are supported:.The content of this file must be a JSON object whose keys form identifiers to be used as the values of the above style properties, and whose values are objects describing the dimensions ( width and height properties) and pixel ratio ( pixelRatio) of the image and its location within the sprite ( x and" and vector tile features with a icon property with the value poi. An index file, which is a JSON document containing a description of each image contained in the sprite."sprite" : ""Ī valid sprite source must supply two types of files: Default is 75.A style's sprite property supplies a URL template for loading small images to use in rendering background -pattern, fill -pattern, line -pattern, fill -extrusion -pattern and icon -image style properties. The following configuration options are available to further customize the webp output: -webp-quality = WEBP tiledriver support is new to GDAL 3.6. The –url option is also used to substitute $ in the template MapML file. Template_tiles.mapml file from GDAL data resources The generated MapML file in the output directory is mapml.maplĪvailable options are: -mapml-template = įilename of a template mapml file where variables willīe substituted. Geodetic: mapped to WGS84 MapML tiling schemeĪPSTILE: from the tms_MapML_APSTILE.json data file Mercator: mapped to OSMTILE MapML tiling scheme –xyz is implied, as well as –tmscompatible if –profile=geodetic. Gdal2tiles.py is a Python script that needs to be run against Python GDAL binding. Web viewer to generate (all, google, openlayers, leaflet, mapml, none) - default ‘all’. Options for generated HTML viewers a la Google Maps -w, -webviewer = URL address where the generated tiles are going to be published. For a dataset with different projection use with caution! -n, -no-kml Īvoid automatic generation of KML files for EPSG:4326. Generate KML for Google Earth - default for ‘geodetic’ profile and ‘raster’ in EPSG:4326. Options for generated Google Earth SuperOverlay metadata -k, -force-kml In XYZ mode (used by OGC WMTS too), tiles at y=0 are the northern-most tiles. In the default mode (TMS), tiles at y=0 are the southern-most tiles, whereas Generate XYZ tiles (OSM Slippy Map standard) instead of TMS. The spatial reference system used for the source input data. Resampling method (average, near, bilinear, cubic, cubicspline, lanczos, antialias, mode, max, min, med, q1, q3) - default ‘average’. Placed in GDAL data directory (provided all zoom levels use same origin, tile dimensions,Īnd resolution between consecutive zoom levels vary by a factor of two). Starting with GDAL 3.2, additional profiles are available from tms_XXXX.json files Tile cutting profile (mercator, geodetic, raster) - default ‘mercator’ (Google Maps compatible). An example driver config option is GDAL_PDF_DPI, which can be found at Configuration options -p, -profile = World files and embedded georeferencing is used during tile generation, but youĬan publish a picture without proper georeferencing too.Ĭonfig options of the input drivers may have an effect on the output of gdal2tiles. SuperOverlay), in case the supplied map uses EPSG:4326 projection. GDAL2Tiles also creates the necessary metadata for Google Earth (KML You only need to upload the generated directory onto a web server. Special software (like MapServer) and the map displays very fast in the Google Maps, OpenLayers and Leaflet are generated as well - so anybody can comfortablyĮxplore your maps on-line and you do not need to install or configure any The OSGeo Tile Map Service Specification. This utility generates a directory with small tiles and metadata, following
