Topo Maps :: Beta

A new app, provisionally called simply Topo Maps 2, is currently in development. Ultimately this app will replace the existing app, but they will co-exist for the time being.

A test version of the new app is now available to anyone who has the current Topo Maps or Topo Maps for iPad installed. The test version is distributed using an Apple system called TestFlight. To get started, Click Here. (If you are subsequently asked to enter a code or link, come back here and click the same link again.)

Please try it out and send your feedback. But do please read the notes below!

The new app will include significant new features, many of which have been frequently requested over the years, including:

Much of this functionality is shared with my other apps for the UK and New Zealand. See below for some preliminary screenshots.

Release Notes

February 6, 2024 - build 24399

Important: your existing 1:63k maps of Alaska will be removed by this update. You will need to re-download those maps.

Alaskan 1:63k maps are now shown as a separate category in the Maps screen and hence have a separate grid, making it possible to select the maps that you want where both 1:24k and 1:63k maps are available. Canadian maps are now also shown as a separate category, for consistency.

The app now has a mechanism for presenting "hints"; any suggestions about where hints would be useful would be appreciated.

Please tell me what you think! For example, what do you think of the maps and imagery? What about the hybrid map mode? Have you tried recording tracks? Did that work well? Thanks!

January 12, 2024 - build 24323

This is a bug-fix update.

See below for older versions.

Important Notes about the test version

How to send your feedback

It's probably best to send your feedback by email. Please attach a screenshot if you think it will help describe what you are seeing.

TestFlight does provide a couple of mechanisms to send feedback. If the app crashes, you can send the crash report along with a description; you can also send screenshots. Note that if you use either of these features I probably don't see your email address, so I have no way of replying. Consider putting your email address in your comments.

What to look for

I would especially appreciate feedback about any of the following:

Known Issues

The following are areas where I know that work is required before release; you don't need to send detailed reports about these:

How the TestFlight Beta Test works

The app that you install using TestFlight will work much like an app installed from the App Store, except that it will expire and cease to work after about 90 days. When I release updated test versions you should be notified that they are available; they may be installed automatically if you have enabled that in the TestFlight app.

Eventually, when the final version is ready you'll be able to install that from the App Store. Note that I believe there is no automatic notification about that from the TestFlight system, as far as I can tell.

I have not yet decided on the business model for the new app. It may include a subscription element. It won't be free.

December 4, 2023 - build 24201

I have processed about 56,000 maps and I think most are OK, but there are some glitches:

Please report any other issues not listed above that you spot with these maps! I obviously can't inspect all 56,000 of them myself. Please check a few of your local maps and see if they align properly with adjacent maps, etc., and make sure that they are at least as new as the same quad in the old app.

This is a bug-fix update which should resolve many of the visual glitches seen in 3D mode.
