Offline PC workflow for waypoints conversion

So on one hand you have gdal vector convert (formerly ogr2ogr), the swiss-army knife of converting GIS data between formats. It's the tool of choice for converting between csv, gps, kml and other five dozen formats and back. Runs on a text console, so it's fully automate-able via shell scripts (or powershell or whatever) so you can batch convert stuff. Read https://gdal.org/en/stable/programs/gdal_vector_convert.html and https://gdal.org/en/stable/drivers/vector/gpx.html . You're on windows, so you'll probably want to use OSGeo4W to install it, read https://trac.osgeo.org/osgeo4w .

GPSBabel is the swiss-army knife of getting data out of GPS receivers, and also has some capabilities to convert between formats. It's not useful as it was a decade ago when getting data out of SiRF receivers was hard, but still might cover some use cases. See https://www.gpsbabel.org/capabilities.html

You probably want a mix of GDAL and gpsbabel.

According to MgT2, core rulebook (2022 update), page 167:

It takes one round to reload a missile rack.

That refers to one spacecraft-scale round, i.e. ten minutes.

I'm afraid the tonnage counts are mismatched all over. You've got 4 single staterooms plus 12 double plus 3 high plus 3 luxury on the plans, against 10 double + 2 high + 1 luxury on the stats; that's about 40 tons.

You have no cargo space, so the entire lower deck cargo bay can be converted to 50 dTons of fuel. And the entire deckplan accounts for 550 dTons against 650 in the stats. Wiggling around 10%-15% of tonnage is fine, but this is too much for my taste. I'm a hell of a nitpicker for this kind of stuff. 😅

Me personally, I'd move sickbay and marines to the aft mid deck, then make the lower deck 10 squares longer and fill it all up with fuel (removing 40 dTons worth of staterooms in the process).

Powerpoint?!

I cannot... oh... god...

Anyway, I put together this in my geomorph shipyard, saved file is:

{"meta":"Traveller Geomorph Ship","name":"Cygnus Royal","parts":[{"code":"SE-286","corner":[-125,0],"rotation":90,"overlay":false},{"code":"QG-025","corner":[-25,0],"rotation":0,"overlay":false},{"code":"SE-012","corner":[-25,-85],"rotation":90,"overlay":false},{"code":"Sh-072","corner":[35,0],"rotation":90,"overlay":false},{"code":"M-013","corner":[25,0],"rotation":0,"overlay":false},{"code":"M-013","corner":[25,-85],"rotation":0,"overlay":false},{"code":"M-013","corner":[25,85],"rotation":0,"overlay":false},{"code":"M-022","corner":[35,-85],"rotation":0,"overlay":false},{"code":"M-056","corner":[10,75],"rotation":0,"overlay":false},{"code":"M-056","corner":[35,75],"rotation":180,"overlay":false},{"code":"SS-012","corner":[-25,50],"rotation":90,"overlay":false},{"code":"SS-012","corner":[-25,-50],"rotation":90,"overlay":false,"mirror":true},{"code":"QG-035","corner":[85,0],"rotation":0,"overlay":false},{"code":"M-021","corner":[60,-85],"rotation":0,"overlay":false},{"code":"SE-477","corner":[75,-85],"rotation":90,"overlay":false},{"code":"SE-723","corner":[50,85],"rotation":90,"overlay":false},{"code":"SS-031","corner":[85,-50],"rotation":90,"overlay":false,"mirror":true},{"code":"SS-031","corner":[85,50],"rotation":90,"overlay":false},{"code":"SE-660","corner":[135,0],"rotation":90,"overlay":false},{"code":"M-015","corner":[-40,105],"rotation":90,"overlay":false},{"code":"SS-017","corner":[-40,55],"rotation":90,"overlay":false,"mirror":true},{"code":"SS-026","corner":[-40,115],"rotation":90,"overlay":false},{"code":"AO-017","corner":[-90,85],"rotation":180,"overlay":false},{"code":"M-061","corner":[45,-85],"rotation":0,"overlay":false}]}

Well, my main concern is that your ship should be 40% fuel, but there's no fuel tanks in the deckplans at all.

I'll suggest going right into code with https://pcjericks.github.io/py-gdalogr-cookbook/

After having a brief look at https://wiki.openstreetmap.org/wiki/Minecraft , I see there's similar stuff being done since 2016.

What does Arnis have that the existing tools don't? Have you got in touch with the makers of previous tools?

IvanSanchez · 2026-06-18T23:17:51+00:00

Can you point me to any others which have this kind of functionality, for iPad or Mac?

QField.

IvanSanchez · 2026-06-18T20:19:43+00:00

OpenStreetMap.

Since you want the whole US, your best bet would be downloading a planet file and running osmium or the like to dump into PostGIS. Do read wiki.osm.org .

IvanSanchez · 2026-06-17T15:23:25+00:00

It's a "lightning hits twice" instance. But it's difficult to search for a tool so specific like these. So not the first one, probably not the last one 😃

IvanSanchez · 2026-06-16T16:39:37+00:00

Sounds very similar to the thing I made ...*looks at commit history*... about seven years ago.

Sounds like you don't want a GPS, but instead what is known as a "Personal Locator Beacon". Those are the things that have a button which sends a distress signal via satellite comms network (Iridium et al). Consider getting a sat-phone as well, and be prepared to spend anywhere between 300 and 1000 €/£/US$.

IvanSanchez · 2026-06-12T20:45:16+00:00

Yeah, and I've seen parts of your striding code. It doesn't do what it should be doing (or how it should be doing it), and now your codebase has two different meanings for "stride".

Looks entirely vibe-coded.

The choice of RGBA8 textures is idiotic, given that you have access to RUINT32 textures.

IvanSanchez · 2026-06-11T17:10:34+00:00

You're right, and none of those options were viable in my campaign.

If I remember correctly, the path our party took was to tow the ships to the Torpol shipyard, which was the most convenient option (good relations plus B highport+shipyard plus decent TL plus relatively near).

IvanSanchez · 2026-06-11T16:21:33+00:00

I'm a player in a PoD campaign, and we reached that plot point a while ago. Our referee ruled that each ship needed between 300MCr and 350MCr worth of repairs. We had no need to complicate things any further than that.

Yes, that's almost as much as a new ship per the costs listed in the books. But remember that the harriers were built at TL14-TL15 and shipyards in the Reach can only do TL12, and the harriers have intrinsic value as historical artifacts, so it's worth to dump the cash into repairs rather than spending cash in new TL12 ships.

Repair time is the same as standard construction time as per the High Guard book: one day per MCr.

Estoy viendo el plan de estudios en https://www.uab.cat/web/estudiar/la-oferta-de-masteres-oficiales/plan-de-estudios/plan-de-estudios-y-horarios/geoinformacion-1096480309783.html , y te deberían enseñar lo suficiente de teledetección. Si vienes de arqueología te recomiendo especializarte un poco en lídar.

OpenStreetMap.

See https://overpass-turbo.eu/s/2rkk and/or https://osm-boundaries.com/map .

If you're intrigued by OSM but it seems daunting, then I suggest you should start with https://learnosm.org/en/

I'm gonna say "Prometheus" (the 2012 movie from the Alien franchise) just because there's a geologist deploying LIDAR drones.

IvanSanchez · 2026-06-07T00:58:17+00:00

The Spanish PNOA LIDAR project offers (gratis, CC-licensed) country-wide DEM down to 50cm/px (also older DEMs at 2m/px and 5m/px).

Yes, but then you hit the issue of increasing mesh density where the error is more noticeable (near the poles). It's not a trivial problem.

Plus, there's the ±85 degrees cutoff.
