Nor is there a way to control the compression/quality level of the PNG/JPG images created by the tile-cutting process. Crucially, I could see no way to specify the resampling method used when warping the input raster file into the Spherical Mercatorprojection suitable for Bing Maps / Google Maps, and resizing the data for different zoom levels. Secondly, the front-end MapTiler interface does not expose all of the possible parameters of the underlying script.Reading through the release notes on the GDAL site shows several bug fixes and enhancements have been introduced to the GDAL2Tiles.py script between these two versions. However, the GDAL2Tiles.py script maintained as part of the GDAL library, and packaged with the latest GDAL 1.8.1RC2release, is version 19288, dated April 2010. Firstly, the source code repository reveals that the current MapTiler executable was compiled using version 15748 of the GDAL2Tiles.py script, dated November 2008.The current version of MapTiler (download from ), for me, has three main shortcomings: However, like many GUI applications, in the process of simplifying the experience for the end user, MapTiler also loses some of the flexibility and power of the underlying script. Generally speaking, the application is reliable, easy-to-use, and generates pretty good quality results. This is an admirable objective in itself because, as noted in previous posts, simply trying to compile the components of a typical spatial tool chain can be quite a headache. Like all GUI wrappers, it provides a convenient front-end interface, and doesn’t require the end user to have any knowledge of command-line processing or build tools. MapTiler is essentially just a GUI wrapper around the GDAL2Tiles.py python script, which is distributed as part of GDAL. MapTiler is a Windows application that will reproject and cut any GDAL-supported datasource into a set of 256px x 256px image tiles, suitable for use as a custom tile layer in Google Maps or Bing Maps et al. ', rendered by HERE and partly based upon OpenStreetMap data are offered.So I’ve been using MapTiler to create some quick raster tilesets from a set of GeoTIFF images. Instead, the map services MapTiler and 'PTV. Neither any user defined map service added toĮdit -> User preferences -> GUI -> Background mapĬontacting OpenStreetMap (or Google) will not work without any license. Note: For PTV Visum 16 and older: Replace "https" by "http".įor PTV Vissim/Vistro 2020 (and older) is no workaround available and we recommend to use the Map services offered with PTV Vissim/Vistro 2021. The PTV Group is not responsible for these map services which might be slower. To add them as map services the contents of the XML file are added to the User preferences: It contains 3 URL templates which can be used as a replacement for OpenStreetMap. The map services offered by Munidialis when complying with the OpenStreetMap license URL templates as XML file is attached. The map service "WMS TopPlusOpen" for which an URL template as XML file is attached. Note that since the introduction of PTV Visum/Vissim 2021 the Background map 'OpenStreetMap' is not offered anymore, as the map service 'OpenStreetMap' is not intended for commercial purposes and its use lacks any contractual basis: This is caused by changes implemented by the community. We have identified that the map service OpenStreetMap cannot be loaded anymore from PTV Visum/Vissim 2020 (and older) since July 2022. The server of the map service used might not be available temporarily.

When choosing OpenStreetMap as map service the following error messages (or similar) may occur:
