osrmtime: does not calculate distances and deletes original GPS information

[Marieke Volkert]

Dear Stata List,

my aim is to calculate distances via osrmtime after having geocodes adresses via "geocodehere". Unfortunately I fail to calculate any distances and after running osrmtime most of the original values are deleted. Let me explain how I proceeded:

1. I downloaded my .osrm file via http://download.geofabrik.de as well as via http://extract.bbbike.org/ - the results after osrmtime remain the same.
2. I installed the osrm time automatically
3. osrm Calculation fails (syntax and output follows) and deletes most of the original inserted gps information (see list below)

I would be happy if someone has an idea what I didn't see...

Thanks in advance

Marieke

As you can see the output variable distance etc. remain empty while most of the values of the input variables are deleted.

Update: I contacted the programmer of the ado who could help me out with additional code. But I am not really able to explain what actually went wrong.

Using the latest ado-files available at http://www.uni-regensburg.de/wirtsch...ime_online.zip
solved the issue.

Best,
