A pet project I've wanted to do for ages is to hack up a very high-detail (factoring in every road/footpath) isochrone map centred around my home, using openstreetmap data and render the result for a printshop at e.g. 600dpi to create a high quality map/poster Any suggestions for the best (open) software to achieve this?

Mapbox also does isochrones: https://blog.mapbox.com/add-isochrones-to-your-next-applicat...

disclosure: I work for Mapbox (on geocoding, not visual maps)

I vaguely built something similar for Sydney, but in showing how good/bad public transport is than driving (hint: it's way worse to catch PT): http://www.publictransport-or-drive.com/

It pretty much makes a isochrone maps all over the city, and gets google public transport and driving times and creates a ratio. I've started to work on a better version 2, but so far not much work.

I had this idea 15 years ago, although I was thinking you could manipulate the visual distance on the map to make it look physically closer, kind of like a topological map. It would take the current traffic, etc to take into account how close things were in time vs distance.

But I was never smart enough to implement it. This goes a bit along the way but hopefully someone comes along and implements that, I think I would find it very useful.

By removing literal geography, we now have a map that more closely reflects the way we think about our environment: a cluster of restaurants “five minutes that way” versus “ten minutes the other.”

Speak for yourself! I feel way more confident getting around when I know the actual geography.

There are many interactive isochrone maps with sliders - one such example is [1]. Other isochrone maps listed here [2] may also have time sliders. [1]: http://property.mapumental.com [2]: https://wiki.openstreetmap.org/wiki/Isochrone#Examples

They're all public transit. I'm looking for general roads, re: "I'm here, where can I drive to in 35 minutes?"

Mapbox actually has this! Peter, the author, shared our github plugin to generate isochrones in your browser. https://blog.mapbox.com/add-isochrones-to-your-next-applicat...

The problem isn't in getting the data for the transformation but to figure out which transformation to use. It's not possible to do in the general case, imagine e.g. an infinitely quick circle line. Where do you put the part of the map that's inside the circle?

I think as far as figuring out the transformation to use on the a generic map I would: 0) ignore stuff like "infinitely quick" since that isn't realistic for what we are doing :-) 1) For the map I am displaying, pick a handful of points of interest to hse as controls, as well as my current location. 2) Use existing data we already have for stuff like direction routing to get travel times between all the pairs in our…

There's no reason your distance graph should correspond to any continuous mapping of the plane. Two distances constrain a third point to one of two spots. Add a third distance and unless you get lucky, there will be no valid corresponding point in the codomain.

Interesting concept. I like the overlay idea, but I think simply having that as a standalone map would not be useful in other areas where distance as the crow flies ≠ time traveled. Areas with large bodies of water (like adjacent peninsulas), mountainous areas or areas with strange road infrastructure (Some parts of Virginia). Nonetheless, an interesting concept!

The distance changes as you change your mode of transportation - so barriers would be taken into account for the time traveled.
