Hi Jürgen,

I tested the "GPS course format". Using GPS conditional access is a very good idea for a Moodle add-on but I found some problems.

1.
You only can use the course with a device that uses a gps receiver. So you can use the Moodle course with an iPhone, an iPad wifi+cellular and an Android with GPS. You can't see anything in the Moodle course if you try to access with a desktop pc, a notebook, an iPad wifi (without cellular) or any other device without GPS.

2.
The "GPS course format" hides complete topics in a course. Moodle conditional access should conditionally hide a topic but also every course activity separately.

3.
If you once added a position to a topic you can't delete the GPS condition anymore. So you can't decide later to show the topic to course students staying everywhere.

4.
You can't move topics in a course. If you try to do so the topic moves but the GPS condition stays on its old place.

5.
The backup and restore process looses all GPS access conditions so you can't duplicate such a course in the same Moodle or copy the course from one Moodle to another one.

You should try to get a better implementation of the GPS conditional access into Moodle.

A.
The Moodle course must work on every device. The GPS driven activity should be hidden if Moodle gets the wrong GPS location or no GPS location.

B.
The GPS condition should not be a course format. It should get an activity access condition same as "before date", "until date", "score less than", or "score higher than".

C.
The trainer must be able to set the location but he also must be able to delete it.

D.
If a trainer moves an activity with a GPS location then the activity must move together with the location. And if the topics has a GPS location the the topic must move together with the location.

E.
The backup process must save the course completely ... this means that it must also save the GPS conditions. And the restore process must recover the GPS conditions if the GPS add-on is installed also in the target platform.

I hope we will get a nice add-on for Moodle with GPS conditional access!

Best regards, Ralf
