Ding...ding...Speed Camera Database...ding...ding..ding

[M7]

I dowloaded the camera update yesterday onto my Zumo and am not happy with it but that may be my fault for not setting it up properly.
It is a very comprehensive database showing an accurate location of all cameras.
Unfortunatly the Zumo warns me of every camera including red light cameras and cameras in the opposite carriageway neither of which I want.
I also get warned too far ahead of the camera sometines more than half a mile.
On a ride yesterday there was an alarm going off virtually all the time from Wandsworth to Esher along the A3.
It became so distracting that I ended up turning the thing off, which rather defeats the point of having it.
Is there a way of turning off red light and opposite carriageway cameras so the warnings I am getting are relevent to me?

Hi and welcome.

If you download and use the Consolidated Database you can choose to omit certain camera files such as the Mobiles and RedLights, by simply not loading them.

Unfortunately Garmin only allow their own database to use Directional Data to distinguish between cameras on your side of the road and the other side of the road.

You can edit the alert distances with POILoader by selecting Custom mode, or you can use Ash10s Camera Manager from here which allows further customisation of the way the database alerts work.

That sounds like a challenge Sal

the cyclops database file is .gpi file just like those that poiloader creates so we know 3 things:

1) .gpi files can handle directional data
2) there MUST be a program (special version of poi loader?) that can create these
3) garmin are spoil sports

sallyann, there is software that can convert gpi to csv BUT the garmin database is, obviously, encrypted and cannot be converted this way. not sure on the legality of 'breaking' that encryption though...

If it were simple we'd have done it, the data is encrypted. Nothing illegal about attempting to decipher the encryption format if all you wish is to offer your own data in the same format.

What you can't do obviously is extract and use the their data not that we'd wish to as ours is far better!

It would depend on the licence conditions that came with the software. Usually, but not always, there is a clause that forbids reverse-engineering. Someone with a licence would have to check.

Edit: Darren, I never suggested it would be simple. Hard just takes longer.

I would go along with this definition from Wiki

"Reverse engineering (RE) is the process of discovering the technological principles of a device, object or system through analysis of its structure, function and operation."

[Darren]

Indeed, and my point was that you can't forbid this type of reverse engineering, see here.

[Sallyann]

Darren,
I don't think we are in disagreement.
There is a huge amount of case law about this and as a software developer I try to keep it touch with it. The most crucial thing though it what the individual software licence says. It should specify what can be done or not done by the licensee, and it over-rides any general principles.

I am just a little surprised though that you say "All moot anyway as being encrypted its unlikely to be easily understood." How heavily is it encrypted? Has anyone actually tried?

[Darren]

I can email you a sample file if you want to take a look?
