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.

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.

5 JavaScript mapping APIs compared
Leaflet stands out as one of the top open source JavaScript libraries for crafting interactive maps. Optimized for both mobile and web devices, it is relatively small (around 42KB) and offers a ton of features, plugins, and a straightforward API. It works across all browsers and platforms.

Shots: Create Mockups
Finding maplibre 'better' was more valid at the time than today, and is also subjective. The creators and maintainers of both libraries have done some great work (and are still doing so).
Back in January 2022, the stable version of leaflet, v1.7.1, was from September 2020, and was affected by some small bugs degrading the user experience. Although the release of following version seemed close, there was no clear schedule for it, and I had concerns about how maintained the library would remain.
As of today, the bug from 2015 where there is some white space between map tiles on fractional zoom levels [0] is still open.
Also, leaflet was a pain to integrate in Svelte Kit framework, because it depended on `window` and-or `document`, not available at server side.
Maplibre, on the other hands, with a feature set roughly equivalent to Leaflet, benefited from much more frequent releases, and seemed more stable across browsers and devices. It was also easier to make it work in Svelte kit.

Ask HN: When building with complex maps do you go with GMaps, Mapbox, OSM?
None of those things are what most in the GIS space would consider "complex", so you could go with any of the options you selected. For lightweight maps, I like Leaflet
