![]() ![]() By default, the automatic order is selected based on a number of GCP points. Supported orders are 0 (auto), 1 (affine) and 2 (polynomial of second order). order Īn option to set the polynomial order for transformation method of assigned GCPs. At least three control points are required. The last element (elevation) is mostly zero. Each GCP is defined by the position on the raster (pixel_x and pixel_y), which is associated with a georeferenced location (easting northing ). The geolocation can be specified using three or more control points - GCP (Ground Control Point). This option can be used with WGS84 Coordinate System (EPSG:4326) as arguments lng1 lat1 lng2 lat2 lng3 lat3, which will set up -srs EPSG:4326 for files without a specified Coordinate system. To assign affine transformation with 3 corner points:. georeference Īn option to load external georeference from World File, Tab File, OziExplorer Map File or. This option can be also used with its short name -gt. To assign affine transformation directly. To manually set bounds of a file in the specified spatial reference system. To enforce a custom selected georeference information or loading from external files these options are available: -bbox MapTiler Engine is loading the geolocation automatically from the internal headers of the input files (such as GeoTIFF) or from external supportive files (such as ESRI WorldFile) if they are available. Georeferencing can also be done visually using GUI or online tool.įor proper rendering of the maps the location of supplied input files in the known coordinate system (SRS) must be available. Maptiler-engine -o tiles map.tif -nodata 0 0 0 To search for identifiers or definitions use EPSG.io or .Įxample of assigning the United Kingdom spatial reference OSGB to a GeoTIFF file before rendering: Can be WKT, EPSG code in the form of ‘epsg:XXXX’, PROJ.4 string. In case this information is missing in the supplied file or it is incorrect (the maptiler place the maps on a wrong location, you can still assign the information about the spatial reference system with an option: -srs ĭataset projection. ![]() In case the input files contain already the definition of a used coordinate system (SRS) then MapTiler Engine is able to load it and directly use this information for the transformation of the maps. geodetic datum + map projection with parameters) is supported, which means the software can process almost any geodata you may have available from all over the world. Practically any modern existing georeferencing coordinate system (SRS - spatial reference system, e.g. The complete list of supported formats is available online here. MapTiler Engine is able to open and process a large number of raster geodata formats, including: GeoTIFF, Erdas Imagine, ECW, MrSID, JPEG2000, SDTS, DTED, NITF, HDF4/5, BSB/KAP, OziExplorer, etc. The input files and related options Supported input file formats ![]()
