World Maps for Download

No Street Names

A clean map without street names, ideal when you want to minimize visual clutter.

With Street Names — Recommended

Includes street names for easier navigation and identification.

Note: The BSC may not render streets correctly when there is too much information on the map. For the best results, this version is recommended.

With Water

Includes water features such as lakes, rivers...

With Forest & Grassland

Includes forest and grassland areas for a more detailed representation of the landscape.

IGPSPORT BSC300 / BSC300T Map Creator

This is a clone from https://github.com/adrianf0/bsc300_maps with an added CI step so github builds maps and ported to python for simpler math (no original code remains). If you are logged in to github you should be able to download the artifacts. Ping me if a map update is wanted or a country should be added (or fork the repo and trigger a CI run).

It is based on the description by CYMES source but the maps are heavily filtered and modified.

The idea is that we have up to date maps and not rely on the igpsport maps from 2023 and regions that are not officially available. Also, the maps are shit. If someone is interested, this are the maps that came preinstalled on my device. Only open the link on a performant browser (not on mobile).

Improvments:

Original iGPSPORT Map	New Map	OSM
cycleway is included in the maps but not rendered as it is too crowded	contains cycleway
random stuff included	inaccessible streets removed
from 2023	up to date

in cruiser:

Original iGPSPORT Map	New Map
includes a lot of random stuff making the file bigger (e.g. footway/sidewalks)	also not perfect, missing one road (highway=service and no bicycle=* tag, should be fixed in osm)
highly simplified	way better resolution
cycleway is useless as it is not rendered on the device (too crowded)	everything rendered

Map format

• Format is mapsforge
• Renderer on the BSC300:

  • anything you want green use landuse=grass (--modify-tags="landuse=something to =grass" or leisure=garden to landuse=grass)

  • it can only render some amount of roads/ways. Even the original maps are not rendered fully. Random roads are missing.

    • thats the reason why I filter extensively which ways to add.

  • Code on this repo does not use simplification-factor for zoom levels 13 and 14. Original uses some factor > 0.5 making the maps even smaller but less accurate

  • Supported tags (colors from night mode):

    • thick yellow line
      • primary
      • primary_link
      • trunk
      • trunk_link
    • less thick yellow
      • secondary
      • secondary_link
      • tertiary
      • tertiary_link
    • thin white line
      • cycleway
      • living_street
      • pedestrian
      • track
    • medium thick gray
      • residential
      • road
      • unclassified
      • service (destroys other stuff like living street?)

  • Not rendered tags examples (some are included in igpsport maps...):

    • path
    • footway
    • motorway
    • motorway_link
    • bridleway
    • construction

Usage

Run the tool with the following syntax:

python generate_map.py -i input_map_file.pbf -c DE -s 1200

• Input map files can be downloaded from Geofabrik.
• The output will be a .map file, automatically generated with the correct extension.
• The output filename must follow a specific format to be recognized by BSC300 firmware, it will be calculated in the script.

Output Filename Format

The filename should include:

• Country code
• 4-digit region code
• Date in the format YYMMDD
• Coordinates in base36 (see python code for calculation)
