Thank you for building leaflet. It (and scrapy) are how I wound up finding the house I live in now - a quirky, dirt cheap cottage I'd never have taken note of without the tools to filter and visualize a whole country's listings.
You wouldn't happen to have the tools to still do that, would you?

What country and how did you get their listings?
We use OpenLayers at our company. We are building an interactive map with a bunch of tools for measuring distance, calculating routes, drawing features, displaying diagrams right on top of the map, and OpenLayers is doing wonders for us. It has a steep learning curve but once you grasp the fundamentals, you can figure out how to do all kinds of magic tricks with it.

Thanks for sharing! One more curiosity - what PNG compression tool was used and how long did it take to crunch 216GB to 17GB? I'm surprised it didn't crash.
I didn't compress an actual image from 216GB to 17GB. Instead, I created the highest resolution image already as a set of tiles (each one 5000x10000 px). Then I tiled them further in two additional zoom levels, until I got 4x8 square tiles of 1250x1250px. From there I worked backwards merging chunks of 2x2 tiles. The figure 217 GB comes from the cumulative size of all the pandas DataFrames containing the whole datase…

What's your company?
Leaflet author here! Just wanted to note that if you haven't looked into OpenLayers in a few years, you absolutely should — it's astonishing how much it progressed: from something that I was so frustrated with that it prompted me to write Leaflet in the first place (11 years ago) to a modern, fast, well-engineered and lovingly maintained library. It's especially great when you're doing complex GIS stuff and need a to…
Thanks for creating Leaflet and Mapbox GL! Do you have any specific examples of "complex GIS stuff" (Uses OpenLayers) or a "highly interactive app" (Uses MapBox GL)? Are there any big feature gaps from leaflet->mapbox-gl that developers should consider when choosing a mapping library?
When I was working with this stuff, Leaflet was more "view only" and not so much editing. This was back in the "have to support IE6" days. I remember trying Leaflet for a simple project, but gave up since I could not set a bounding box for panning (the map was only supposed to show a limited area of the world), while OpenLayers seemed had every API feature one could wish. Although more bloated, less polished :)

To answer your question: Leaflet.draw is superior to mapbox-gl-draw. mapbox-gl-draw is very lightly maintained and is not as full featured as Leaflet.draw. mapbox-gl-draw sounds like it may also be no longer maintained by Mapbox in the future either - refer to the recent GitHub issue on the repos that hints at this. There are mapbox-gl-draw plugins to make it comparable to Leaflet.draw but these are features IMO that…
