Examples of interactive guidebooks?

Hi all. I am considering starting a hobby project of writing a guidebook for a local area.

During my work as a software engineer I have worked with software libraries like quarto that allow writing technical publications that can be formatted to a variety of formats, including as a website and PDF. See this website for an example.

I see a lot of benefits of this:

1. Export as a PDF, for offline use on your phone, or print to actual paper. This also means 0 printing costs for the author if they are trying to distribute their book for free.
2. All the goodies of a website: search, interactive maps, diagrams, links, live weather, updates and corrections are instantaneous, heck even comments.

Has anyone seen any examples of guidebooks like this, that have a website component on equal footing as the actual book? See any problems with this approach? Trying to get a survey of the landscape. Thanks all!

rockfax has their guidebooks in print and digital format. You can download the app, and then download areas to your phone. They have interactive map features with gps coordinates etc

A little different than what you're talking about but fairly similar

GunksApp is the best guide I have seen. Never thought of printing it…it’s on my phone, why would I want paper.

Toofasttopos is an amazing guide that is sold print and pdf.

The huge leap forward with GunksApp is the author uses the app to show you the start and how to get there.

Not a fan of PDF.

Since you are programmer - probably a better idea is to have "html-type" version of guidebook that may be downloaded to smartphone. Gets rid of pdf overheads and shortcomings. Each phone already has web/html-document browser installed.
