Instruction for the creation of KAP Files

Use Mobac [1] Software to select one or multiple areas for chart generation.

• start the software
• select a tile server e.g. OpenStreetMap 4UMaps.eu
• select GridZoom 16 in upper area of the shown map
• Create New Atlas Content PNG + Worldwide (PNG & PWG)
• Set Menue -> Selection -> Selection Mode -> Rectangle
• Select "15" in zoom level dialog, select multiple zoom levels where needed.
• Use the Mouse to select a area for single chart
• press "add selection" in the "atlas content" dialog
• save the profile e.g. newatlas

note: the atlas will be stored in a xml file located in the mobac software directory (e.g. "C:\tools\Mobile Atlas Creator 2.0.0\mobac-profile-newatlas.xml").

clone project and call python scripts to create kap file of specific mobac project file

cd ~/
git clone https://github.com/stevo01/SeaChartCreator
cd SeaChartCreator
git clone [email protected]:OpenSeaMap/chart-projectfiles.git

# fetch tiles
python3 fetch.py -m $MAPSOURCE -d $DB_DIR -q -s -f -i $MAP_DESCR_FILE

# merge tiles
python3 merge.py -d $DB_DIR -q -s -i $MAP_DESCR_FILE 

# build kap file
python3 build.py -t kap -d $DB_DIR -s -i $MAP_DESCR_FILE

# build mbtile file
python3 build.py -t mbtiles -d $DB_DIR -s -i $MAP_DESCR_FILE

notes:

• the generated kap file is located in directory ./work/kap/
• the generated mbtiles file is located in directory ./work/mbtiles/
