Building a Dynamic Tile Server Using Cloud Optimized GeoTIFF(COG) with TiTiler
TiTiler is a dynamic tile server built on FastAPI and Rasterio/GDAL. Its main features include support for Cloud Optimized GeoTIFF(COG), multiple projection methods, various output formats (JPEG, JP2, PNG, WEBP, GTIFF, NumpyTile), WMTS, and virtual mosaic. It also provides Lambda and ECS deployment environments using AWS CDK.

Company decided to move away from AutoCAD to something cheaper...
GDAL is the real heart, the python aspect is mostly wrappers around that I'm fairly sure. I love python for the record, the only reason I bring it up, is cause python haters accuse it of being slow, but QGIS drops down to C++ when speed is necessary, like most modern packages do.

gdal 0.15 is out!
gdal 0.15 (repo, docs), a set of Rust bindings for the GDAL library, used for access to geo-spatial data formats, is now out!

What's missing from C# in Godot 4?
GDAL (Geospatial Data Abstraction Library) is a the geospatial data processing library. It handles a lot of Raster/Vector analysis and alteration. gdal_contour and gdal_rasterize which would be used to create isolines (contour lines) . There's more complex processing and analyses than that. More common is reprojecting multiple layers, and some that being as Vector files, into different coordiatne systems.

Not sure if I'm ready to make the jump from Unity yet.
As an example we use GDAL heavily through its C# binds. We do all the additional data processing, that isn't done by the C++ GDAL, in C#. The final results are both Data (held in memory or temp exported to a file), and a normalized Raster Texture that we can display on a TextureRect. Most of the C# data processing scripts aren't even Inheriting from any Godot Class.

What data structure should I use for reading data from a .shp file?
I think this would be the best way to handle this. GDAL is what you should look into for this project.

Protomaps – A free and open source map of the world
I've been using TileServer GL for a while and it looks like there is support for pmtiles coming soon.

Serverless maps at 1/700 the cost of Google Maps API
Firstly, I just want to say thanks for the reply, but more so thanks for your work, its moving opensource mapping forward.
In my work we are looking at switching from mbtiles hosted with tilserver-gl(https://github.com/maptiler/tileserver-gl) to pmtiles to remove a server process. But we we self host already and we are already using maplibre-gl 2.
I can see why the implementation in the blog post would be better for high traffic deployments (ours isn't). It also points out to me I don't understand how a CDN would handle range request for hosting the pmtiles file directly, it probably doesn't?
As far as the mapbox stuff,in my mind, pmtiles is a direct competitor (successor) to the mbtiles format, which was a revolution in comparison to everything that came before it. A successor I welcome because it makes it even easier for me as a developer to self host and not be dependent on a SaaS to run my maps.
The modern opensource map stack wouldn't exist without mapbox and I'm personally grateful to them for that. Most people who use pmtiles will use mapbox's opensource style spec to style them, and descendants of their open source code to render them. But as a developer now its an obvious choice to not use their services after years of using them.
However I'm not doing high traffic stuff and they never made much money off me anyway.

How The Post is replacing Mapbox with open source solutions
https://github.com/maptiler/tileserver-gl makes it really easy. I have a pretty simple pipeline set up to download an OSM extract, convert it to MBTiles, host it in CloudFlare, and render raster tiles with this software.

Does anyone know where to find the global raster set of buildings??
It's not raster directly, but you could use planetiler ( https://github.com/onthegomap/planetiler ) to build a full planet vector map . Then you could use something like TileServer-GL to server the vector map with a style. TileServer-gl ( https://github.com/maptiler/tileserver-gl) would provide a raster source that displays in the style you set on your vector map.

Offline Map Tiles
You could host something like tileserver-gl (https://github.com/maptiler/tileserver-gl) and use the pre-generated vector tiles from https://archive.org/details/osm-vector-mbtiles Add some map styles and you have your own offline map service. Here are some good starters for styles: https://github.com/openmaptiles/osm-bright-gl-style
