Android Triangulation and PI

Performing triangulation calculations involves more than a little interaction with PI. Amusing that the Google Play Store rating might come out as PI … 🙂

Rating: 3.14 ≈ PI (3.14159…)

That said, more seriously … some old one star ratings are dragging things down a little. Old ratings that have not been updated when the application has been improved. New features of using the device compass to allow the application to get a bearing, offline support, persistent database, multiple events. Hopefully the application is higher than a three…

If you have the application and find value in it, a rating / review would be greatly appreciated.

Share Triangulation Android

After considering offline sharing (to offline capable maps) of the triangulation on iOS, I realized the same should be possible on Android.

The share coordinate button on the beta version of the Triangulation application, now offers a chooser to allow any installed applications that support the geo:{LATITUDE},{LONGITUDE} scheme to be opened to that location.

Please join the open beta for Field Triangulation and check it out…

Open triangulation in application…

Some application that support this scheme are:

Response Utilities Android version 1.0.16

A new release of Response Utilities for D4H on Android is on Google Play. Version 1.0.16.

It contains improvements for Upcoming where attendance is displayed inline with the activity, and can be used to filter from the user’s perspective: all activities, Mine (ones the user is attending or requested to attend), Attending or Requested. Use this to more easily track down the upcoming activity you are looking for.

Upcoming Activities on Android

Improvements in Recent Activities include filtering by activity type: all activities, just incidents, just exercises or just events. Use this to more easily track down the recent activity you are looking for.

Android Triangulate Rebuilt


I’ve been working to update Triangulate on Android, and that include porting it to Kotlin (Google / Android replacement for Java.) In sort, I’ve changed every line.

Further I’ve worked to improve handling for offline (it was not as simple as I’d first considered, and testing did not uncover that.) Finally I’ve added a first attempt at allowing the devices sensors to help determine a (rough) bearing, enabling some usage even without the (more accurate) handheld compass.

I would appreciate some help checking it out before I overwrite the existing application with this version. Please check it out at:
