Split the OpenStreetMap files into smaller tiles in order to use them on your Garmin device, with this practical command-line utility
Mkgmap splitter is a useful and efficient piece of software designed specifically for the users who want to create and load OpenStreetMap files on their Garmin GPS device. As the name suggests, it was built as a side-project for Mkgmap, and it can convert the data from the large OSM files in tiled versions that are usable by the device.
Mkgmap splitter can calculate the area of each tile by analyzing the node distribution within the OSM file. It can also export the nodes and relations data to multiple files. Seeing how the program does not come with a graphical user interface, it is safe to say that novices will find it a bit overwhelming to handle.
Advanced knowledge, particularly in working with CMD is thus a requirement for successfully performing any task with Mkgmap splitter. At the same time, it is necessary for Java to be installed on the host system, for correct functioning.
To obtain a full list of Mkgmap splitter’s functions, users can run the JAR file from the decompressed archive in CMD, using the ‘java – jar’ argument followed by the program itself, including its full path. Automatically, the available operations are enumerated, for instance ‘split-file’, ‘problem-report’, ‘stop-after=dist’, ‘geonames-file=’, ‘mixed=false’, ‘output-dir=’ and several others.
Moreover, the downloaded archive also comprises a series of helpful documents that will explain to users the role and functioning of Mkgmap splitter, enabling them to discover how an OSM format file can be cut into smaller portions or tiles. It also includes detailed descriptions of each available operation, allowing users to determine which is the one that would best serve their needs.
