Map generator for "BE Graphes"
To clone this repository:
# You need the --recursive option (--recurse-submodules with Git >= 2.13),
# you can use https or ssh, it does not matter.
git clone --recursive https://gitea.typename.fr/INSA/be-graphes-map-generator.git
# Then you need to initialize the repository, this may takes some time as it needs
# to fetch a shapefile (~500MB) on a remote server.
cd be-graphes-map-generator
bash init.sh
If you do not plan on generating maps with coastline for mapsforge (see below), you can use the --no-shapefile
option
to avoid the download:
bash init.sh --no-shapefile
Folders organization
The two main folders are inputs
and outputs
:
-
inputs
mainly contains:- a script
coastline-fix.sh
to merge land/sea polygon (see below) and PBF files; - a directory containing boundinx-box (
bbox
) for specific regions; - a file containing highway filters;
- PBF files downloaded organized in folder
$REGION/$REGION.pbf
.
- a script
-
outputs
is the default folder for generated output.
Obtaining PBF files
You can download PBF files for multiple regions on Geofabrik: https://download.geofabrik.de/index.html
You should put the PBF file in subfolders, e.g. if you want to use bretagne.pbf
, you should save it to:
inputs/bretagne/bretagne.pbf
Doing so will avoid having a messy inputs
folder due to region-specific files generated by coastline-fix.sh
.
Generating maps
Only manual generation is supported as of now:
Mapsforge file:
# You do not need to specify a bounding-box if you did not use the coastline fix or
# do not want it.
bin/osmosis --rb inputs/bretagne/bretagne_merge.pbf \
--mapfile-writer file=outputs/morbihan.mapfg bbox=47.234,-3.598,47.997,-1.648 threads=2
Binary graph files
# You do not need to specify a bounding box if you do not need it. You can use either "insa2016" or
# "insa2018" writers, and you should change the map id to your need.
bin/osmosis --rb inputs/bretagne/bretagne-latest.osm.pbf \
--used-node --bounding-box top=48.1749 left=-1.7709 right=-1.5014 bottom=48.0644 completeWays=yes \
--tf reject-relations --tf accept-ways highway=(cat inputs/highway-filter.cmd) natural=coastline --lp \
--osm2graph file=outputs/rennes.mapgr writer=insa2018 map-id=0x235
Fixing coastline
When generating mapsforge file that contains sea, you will need to fix the PBF file prior to running osmosis. The fix is an adaptation from https://github.com/mapsforge/mapsforge-creator — It basically does the same but does not download PBF or do the final osmosis run for you.
You will first need a PBF file and its associated polygon file, you can get these from https://download.geofabrik.de/index.html. You need to put those file in a region folder, e.g. if you want to fix bretagne
, you should have:
# Do not rename these files!
inputs/bretagne/bretagne-latest.osm.pbf
inputs/bretagne/bretagne.poly
You should also have run the init.sh
script without the --no-shapefile
option (you should see a folder named land-polygons-split-4326
in the inputs
folder).
Once you have the requested files, you can simply run (from the inputs
folder):
# If you are not already in the inputs folder
cd inputs
# Change bretagne to whatever region...
bash coastline-fix.sh bretagne
