I have access to. I can't figure out what color/symbology the OpenCPN will interpret from the final GPX file.
I had discovered the behind the scenes coding that the MapTech program would recognize. I cannot figure out OpenCPN, so far...
There is no secret or magic here, for route
and track colors OpenCPN follows https://www8.garmin.com/xmlschemas/G...tensionsv3.xsd
(= the <rte> has <extensions><gpxx : RouteExtension><gpxx : DisplayColor>)
The waypoint symbols are the normal <sym> subelement of the <wpt> element as defined by the GPX standard (https://www.topografix.com/GPX/1/1/
) and OpenCPN by default supports the symbols from https://github.com/OpenCPN/OpenCPN/t.../svg/markicons
(In the GPX file use the filename without ".svg" as the value of <sym>) plus any user defined symbols you have.
For a "template" simply export something from OpenCPN as GPX and have a look at it in a text editor.
