The placeholders have the general format of There are some variants even between applications that in principle use the same system, which are noted for completeness sake below.
Placeholders are replaced when the application retrieves imagery files from the source and are replaced by calculated values.
Tile size side length in pixels for the tiles, default 256.Zoom Min and Max zoom levels, these indicates the minimum and maximum zoom levels available and are important for the app to determine over- and under-zoom correctly.Coverage left, bottom, right and top coordinates of a coverage bounding box in WGS84 coordinates, if the values are empty it is assumed that the layer covers the whole visible web-mercator area, that is -180°, -85°, 180°, 85°.the Overlay flag, indicating that the layer is not a background, but partially transparent images for displaying over a background layer.an URL the URL for the source with place holders in the same format as the JOSM imagery sources that Vespucci, JOSM and Go Map!! use as source for standard imagery.a Name this is what is displayed in the Layer control background or overlay selection form.To add a custom layer goto the Preferences screen and select Custom imagery, press the + button to add a new layer. NOTE even though the URLs may look similar to those for a WMS layer, we do not support requesting data from ESRI MapServer with their native protocol. OpenStreetMap / google map tiles (EPSG:3857 and EPSG:900913, later Vespucci versions support EPSG:4326 for WMS servers too), support for layers from OAM and support for imagery layers in MBTiles format. Generating MBTiles files with custom imageryįor Vespucci 10.1 we've added four long requested features: a simple UI to add custom imagery sources, support for WMS servers that support the same projection as conventional.
