S57 END conversion

How to convert an electronic navigational chart to map tiles and how to use them to update OSM data.

I will describe the procdure I used to update the buoys in the Waddenzee. The necessary commands are stored in the makefile, which is in the ZIP with all other resources.

download ENC from https://www.vaarweginformatie.nl/frp/main/#/page/infra_enc
extract the ZIP make unzip
convert the ENC to shape files with ogr2ogr make waddenzee
open them in QGIS using waddenzee.qgs
