New OSM tile server, NVME capacity can be 1 + 1Tb .. or it must be one 2Tb for full planet?

I will let you guys know when I will have the workstation, the courier delivered it but the second package with the extra 32Gb ram was not yet delivered, probably I will have that only on monday, so this weekend I should have time to setup ubuntu, maybe also play with some small files so I understand what each file type does and how I should use it.

The only missing thing so far is the contours files, is there any free source for the contour files? (Sonny DEM, NASA SRTM?) Or the only way to generate contour is to use some scripts that create contours from elevation DEM files (as I briefly read)

I made some progress, I created this style by adding element after element but I have found a few issues with the tiles I generated:

there are some missing elements like [“spring”, “waterfall”, “drinking_water”] man_made=tower,mast,antenna,communications_tower

I think these elements should be in the pbf files I downloaded from geofabrick.de

I want to modify a few elements min_zoom value, some small tracks dissapear to quick, some are hidden from z 13, others from z12 .. I think I ill adjust these one increment lower, instead of 13 it should be 12, instead of 12 it should be 11

I used this script to generate the tiles, it took a few minutes for the whole country (Romania)

~/osm-station/scripts/generate_map.sh romania 24g

#!/bin/bash

Move to the project root

cd “$(dirname “$0”)/..”

Area

AREA=${1:-romania}
MEMORY=${2:-4g}

echo “Building map for: $AREA with $MEMORY RAM…”

java -Xmx$MEMORY -jar bin/planetiler.jar 
–osm-path=data/$AREA-latest.osm.pbf 
–output=data/$AREA.pmtiles 
–area=$AREA 
–force “$@”

echo “Done! Output saved to data/$AREA.pmtiles”

Are there any attributes I can add to this script, or to planetiler, so it exports even more elements, and to adjust the min_zoom level of some categories?

or should I use a different tool for this ?

I also used tippecanoe to generate contours. I love the map so far, I still have many things to style, but now I think the most important things are to find out the easiest / best way to generate all the elements I want (general outdor topo map schema)

cd ~/osm-station/data/elevation/

#We use -i 50 to create a line every 50 meters

gdal_contour -a elev -i 50 romania_elevation.vrt romania_full.json

#Generate PMTiles 

tippecanoe -o ~/osm-station/data/romania_full_contours.pmtiles 
–maximum-zoom=14 --minimum-zoom=9 
–layer=contours --force --simplify-only-low-zooms 
romania_full.json

I haven’t setup the cloudflare tunel yet, so the map is local only for now, but here are a few screenshots:

Zoom level 12.99:

Zoom level 13 bellow. I know the rivers/streams seem to thick but that can be easily style out, the problem is I need these and also all the trails visible even in zoom 12, I will style them to be less visible, but I need them in my tiles at z12.

So can these settings be changed when I run planetile.jar ?

Thanks.
