Go Map!! Update and source code availability

Posted by bryceco on 25 September 2018 in English (English).

Go Map!! is an OSM editor I maintain for use on iPhone and iPad, available from the App Store.

Version 1.6 was released last week, with the primary improvement being support for multipolygon relations, and much improved protection against accidental damage to relations of all types.

More importantly, I’ve published the source code on GitHub if you’d like to contribute or use the code in your own project: Building the source requires a Mac and Xcode. Contributing code requires fluency in Objective-C. It is released under the ISC license, the same as iD.

If you are a frequent user of Go Map!! and wish to be a beta tester please send me an email using the app’s “Bug Reports and Suggestions” button.

Finally, here’s a short video showing basic use of the app:

Go Map!! 1.1 available

Posted by bryceco on 26 February 2013 in English (English).

The 1.1 release of Go Map!! is available in the Apple App Store today. It includes many relatively minor usability improvements:

  • Fixes issues with Russian and Asian street name rendering
  • Improved tagging presets for highways and other ways
  • Auto-complete for all tag values
  • Easier to read street labels
  • Displays house numbers
  • Many new POI icons, especially seamarks
  • Improved login experience
  • Lots of other minor improvements

About 7500 people downloaded version 1.0. Hope you enjoy the update!

Editor usage rates

Posted by bryceco on 2 February 2013 in English (English).

The wiki has a nice page on editor usage statistics showing how many people are using each editor on a year-by-year basis. The data is compiled using data available from this page, where each 550MB archive contains the entire history of changesets starting in 2005.

Because I released Go Map!! about a week ago and the weekly changesets file became available last night I wanted to see the degree to which people are using Go Map!! for real editing. Here are the top editors sorted by number of edits for the week ending Feb 1:

Most frequently used editors

Go Map!! has a very solid showing at position #4 for its first week, and as people become more comfortable with the app’s feature set and mapping on a mobile device it seems entirely reasonable to reach 100K+ edits/week in the near future. Clearly many people want to map on the go, rather that at home in front of a computer.

I was surprised at the proportions of the countries downloading the app. While supporting multiple languages would be nice to have, at least in the short term it doesn’t seem like being English-only is limiting the user base much:

Downloads by country

I’m also disappointed and sorry that a font rendering bug in v1 may make many street names render incorrectly in those Asian countries, and it will be addressed in the next update.

At first most downloads were in the US and Europe, then later in the week Russia and Asia were the largest downloaders. It will be interesting to see at what level download rates stabilize over the next couple months. OSM is a relatively small community and it is hard to predict how quickly market saturation is reached:

Downloads by day

Around 1200 people had downloaded the app when the changeset snapshot was made, but only 170 people had uploaded edits, so the rate of use isn’t as high as I’d like. Part of this might be due to the font rendering bug that affects non-Roman fonts, disenchanting downloaders in Asia/Russia, and part just because of the relative newness of the app.

Go Map!! now available in the App Store

Posted by bryceco on 25 January 2013 in English (English).

My new OpenStreetMap editor for iPhone and iPad is now available for download from the App Store: Go Map!!

Or you can read about features and use on its wiki page.

I have lots of improvements and additional features I’d like to add in later versions and it would be great to have additional beta testers. If you find yourself using Go Map!! on a regular basis and want to receive the latest builds and provide feedback please let me know.

Editor trial run

Posted by bryceco on 24 December 2012 in English (English).

I did a pretty big test of my iPhone OSM editor today. I’m in Mexico and don’t have cellular connectivity, but nevertheless I was able to download the Bing tiles and OSM data at the hotel over wifi, then walk around town adding almost 70 POIs, and then come back to the hotel and upload everything. Full changeset for my walk is here:

OSM editor

Posted by bryceco on 6 December 2012 in English (English).

I am working on a native Cocoa based editor, with the goal of having a reasonably high quality editor for iOS devices. I’m starting with a Cocoa-based desktop editor, will then port it to iPad, and then to iPhone. It will never have all the features of JOSM, and possibly not even Potlatch, but it will be a fast, friendly, easy to use, mobile editor whenever your primary device is an iPhone/iPad and you’d like to do some OSM editing.

If you wonder why we need yet another editor, RichardF (primary author of Potlatch) has a nice overview of the need for new and better editors in his blog (
