aaron parecki’s (@aaronpk) iOS GPS logger works pretty well in conjunction with compass. with one exception though: the underground.

i found compass in the footer of aaron’s new telegraph web app, where it’s listed as part of the p3k suite. compass at p3k.io didn’t work though (it threw 500 errors). so i uncommented 2 lines in AppDelegate.m to use compass at compass.esripdx.com instead of compass.p3k.io.

to make the app upload the location data i had to add a write token that i got from compass.esripdx.com/settings/[database name]. with those hardcoded credentials the ios GPS logger sends it’s data to compass just fine.

nice work aaron, thanks a lot for opening your tools to the public!
