NOAA ENC Charts
I've used Open CPN to download the NOAA ENC charts for California. Downloaded to the /.signalk/charts. It created a series of folders inside i.e. /home/rhumbrunner/.signalk/charts/ENC/US_CA/US1WC01M... Inside those are a series of .txt files. How do I get the Signal K Charts plugin to process these files and make then available to Freeboard SK? I have tried adding the full path inside the plugin like above and still nothing is showing up, only the MBTiles I had previously downloaded are there.

Also is there a way to re-name the way the MBTiles files show up in Freeboard SK they all show up as "SG Area" with a description of "summary". Here's what I get from http://localhost:3000/signalk/v2/api/resources/charts/...
{
"ncds_19a": {
"identifier": "ncds_19a",
"name": "SG_AREA",
"description": "summary",
"bounds": [-123.501111, 15, -116.166667, 33.783333],
"minzoom": 0,
"maxzoom": 17,
"format": "png",
"type": "tilelayer",
"scale": 250000,
"url": "/signalk/v2/api/resources/charts/ncds_19a/{z}/{x}/{y}",
"layers": []
},
"ncds_19b": {
"identifier": "ncds_19b",
"name": "SG_AREA",
"description": "summary",
"bounds": [-123.501111, 33.783333, -113.905556, 37.166667],
"minzoom": 0,
"maxzoom": 16,
"format": "png",
"type": "tilelayer",
"scale": 250000,
"url": "/signalk/v2/api/resources/charts/ncds_19b/{z}/{x}/{y}",
"layers": []
}
}
Firstly S57 enc charts are supported once they have been "tiled" see https://github.com/SignalK/freeboard-sk/blob/master/README.md
Freeboard-SK displays the name from the chart metadata...
So you can change the text in the file to the appropriate value.
bash: docker: command not found
did sudo apt install docker and still getting the command not found
docker installed finally... Hello-world works. Now I get this when I try to produce the tiles.

Dove into the github issues for wdantuma/s57-tiler it's a known issue that there isn't an arm64 docker image... I don't have a Linux based laptop. Is there any other way to product the tiles?
1. git clone https://github.com/wdantuma/s57-tiler.git
2. cd s57-tiler
3. sed -i "s/amd64/arm64/g" Dockerfile
4. docker build -t s57-tiler:latest .
There seems to be some steps missing. When I get to step 4. here's what I get...
rhumbrunner@rhumbrunner:~/s57-tiler $ sudo docker build -tag s57-tiler:latest
[+] Building 0.0s (0/0) docker:default
ERROR: unable to prepare context: path "s57-tiler:latest" not found
If I get it built. Then how do I process the files? I have the unprocessed files in ./ENC and want the output in ./Charts
Thanks for the help...
@Willem Dantuma any ideas
README?
