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

MAP_DESCR_FILE=./sample/atlas/osmcb/sea/osmcb-catalog-test.xml
MAPSOURCE="./sample/mapsource/mp-OpenSeaMap-Bravo.yaml"
DB_DIR="./cache/"

# 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/
