![]() ![]() The file can be either CSV oran OGR dataset (such as ESRI ShapeFile. They specify the cutline (a clipping path)for an input image in pixels or in projected coordinates. 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 specified Coordinate system.Cutline (Crop)There are two command line options for cutline: -cutline and -cutline_proj. prj file.-corners east1 north1 east2 north2 east3 north3 To assign affine transformation with 3 corner points:. This option can be also used with its short name -gt.-georeference An option to load external georeference from World File, Tab File, OziExplorer Map File or. MapTiler is loading the geolocation automatically from the internal headers of the input files (such asGeoTIFF) or from external supportive files (such as ESRI WorldFile) if they are avaialble.To enforce a custom selected georeference information or loading from external files these options are available:-bbox minx miny maxx maxy To manually set bounds of a file in the specified spatial reference system.-geotransform posX scaleX rotX posY rotY scaleY To assign affine transformation directly. You can set a specific color of the map to be considered fully transparent during rendering.Example for removing fully black border around a map:maptiler -o tiles map.tif -nodata 0 0 0Georeference / calibrationFor proper rendering of the maps the location of supplied input files in the known coordinate system (SRS) mustbe available. To search for identifiers or definitions use of assigning the United Kingdom spatial reference OSGB to a GeoTIFF file before rendering:maptiler -o tiles -srs EPSG:27700 map_in_osgb.tifTransparency from a color-nodata This command is typically used to eliminate borders of multiple map sheets that are stitched to- gether. ![]() Can be WKT, EPSG code in the form of ‘epsg:XXXX’, PROJ.4 string. MapTiler Manual Documentation, Release 0.6.3file or it is incorrect (the maptiler place the maps on a wrong location, you can still assign the information about thespatial reference system with an option:-srs Dataset projection. In case this information is missing in the supplied3.5. Map projection with parameters) is supported, which means the software can process almost any geodata you mayhave available from all over the world.In case the input files contains already the definition of used coordinate system (SRS) then MapTiler is able to load itand directly use this information for transformation of the maps. ![]()
