This is really cool! I’m super impressed at how quickly it loads on my phone.

Really great idea to compress the spatial data into Paths.

I would suggest using Natural Earth data instead of OSM so you could drop the ODbL license.

It’d also be really cool if you included the tool that converts the spatial data into Paths.

The bookings are all done through rec.gov

It’s Apache Solr. Most of the data is static, but alerts and events get frequent updates.

The GitHub is mostly outdated repos, although Symbol Library is still active. The developer API is great though.

I'm surprised I don't see more implementations caching and serving vector tiles. I know some (most?) large mapping companies do this.

I maintain a heavily used map of the US, and I found that storing data/serving in vector format seems to be the most efficient (on AWS s3 / DO spaces), and converting to raster in the browser or with a service call / lambda really opens the doors to a lot more use cases. I suspect parent can talk more about this than I can.

After watching this, I made the connection that the French "Bois d'arc" for Osage Orange refers to its use in bows. It turns out that Osage Orange really is one of the best woods for bows.

From PA, can confirm. Also, it's pronounced Leb-nin.

I had a TV that did this exact same thing! Except I was given it as a color "monitor" for an Apple IIE. I would spend hours building my own antennas and spinning the fine tune knob to try to bring in far away signals.

There is also a good buildings dataset from DRCOG that we're (OSM Colorado) importing into OSM. Reach out to us, or come to our next meetup if you're interested.

In many (most?) cases it can be better than the authoritative sources. But there is also the possibility for vandalism or sloppy work.

There are established ways to combat this (peer review, data stewards, reputation scoring) and even OSM has a checkbox for further validation.

OSM will never fit every use case, but it's good to understand where it falls short and can improve.

I used to work in the building with the USGS map store. It was very sad to see it close. It wasn't commercial map providers that caused it to close, it was the avilablilty of USGS topo maps online, and a faster data collection to map pipeline. You can still order maps printed on demand directly from the USGS.

Thanks for posting this here! I feel like this is mostly good constructive criticism.

I have given a few talks about using OSM data in the US government and it comes down to authoritative data sources and validation. It's a great starting point, but there needs to be another layer (or two) of validation before it can be used at the enterprise level. The National Map Corps has some good examples of how this can be implemented with data stewardship.

I am also working on a few projects to take public domain data and put it into OSM. While it's useful and mostly open, it's definitely less open than the original data sources. Another issues is that as soon as someone edits the imported data, it will become less authoritative as well.

Such sad news. Mapzen has been a core component of many projects that I've worked with. They have created and supported many great products that will be missed.

They also have been a big part of supporting the GeoNYC group and helping to organize the OpenStreetMap US conferences.

Thanks for all the maps and data Mapzen!

This could also be used when looking for an Airbnb. You could use it to get a rough price estimate in an area near your destination.
