Directions to your vehicle - in the Vertical?

I probably know the answer to this already, and meant to check it out on my recent trip to NYC. I parked on garage level 2, but was dumped off at level 4. Does the Jaguar Remote Directions to your vehicle allow for elevation differences? I was going to give it a try, but forgot, just wanted to get home....

GPS horizontal accuracy is somewhere at 3 meters or less, vertical probably at least twice that (6 to 9 meters), all depending on how many satellites the receiver picks up on. I think iPhones have a limited bandwidth, so maybe less accurate as it is not collecting all possible GPS signals. I know the iPhone collects elevation data, as I have an app that shows this. Likewise, concrete parking lot, signal reduction as well.

Anyone working in high-rise buildings try this from the upper floors?

They say that "RECOGNIZING" you have a problem , is the key to a *Brighter Future* !!! 0:)

It looks like you are on your way , since you are willing to admit this fact !!!

I just hope it hasn't been "idle" for too many decades !!! I wish you well , theweeb !!! ;)

Every now and then , my mind (that's always going 100-mph) , wonders what it would be like to just "idle" !!! >:)

I don't think I'm understanding the original question.....do you want to know if the app will direct you to "go up three floors" if say you parked on level 3 and are standing at the ground level? Or does it just direct you to the parking structure and then not specify which floor exactly?
Is that what we're trying to figure out? I think it would be cool if it did the first, someone needs to figure this out!

I'm not "trying to figure anything out" ! I'm just goofing around at theweebs expense !
When I park my car in a Parking Garage , I just usually LOOK at what *Floor Color Code* my car is parked on , and the *Floor Level Number* , and then when I go to get back to my car , THAT information that is still logged into my memory will get me right back to my car !!!

It doesn't figure out the reverse, I was trying to find a branch office of my bank and the car kept telling me I was there, an address which had been verified over the phone with a banking officer. I could see no sign of the bank so I parked and after some asking around figured out I was in fact there, I just needed to go up 46 floors. I tried it on google maps while I was in the lobby waiting for my escort up and it told me I was there as well with nothing indicating it wasn't a ground floor outlet. While I was waiting upstairs curiosity had me trying to get directions to my car parking location that Maps conveniently provides and it told me to walk 250 ft east which would have been about a 45 foot walk followed by breaking down a wall and a long fall. o_O Doesn't seem to me like these mapping programs are taking altitude into account.

Thanks all, even the sarcastic ones. I am not sure how I could have rephrased the question, "Directions to your vehicle - in the Vertical?" plus what I wrote I thought was self-explanatory. Yes, say you park on a level in a 10 story garage, but forgot which level, the directions take you to the spot in two dimensions, where you might stand, looking at the screen, supposedly at your vehicle, when in reality it is three floors above or below you.

As I said, the GPS signal is used to determine elevation, and I think it could be incorporated into the application.

Interesting, and what does the telemetry system consist of? How does the FP "know" where it is, if not for GPS? Does it use cell phone triangulation? My thought was the FP system uses GPS, "I am here" and the smart phone uses GPS, "I am here" and then it is a simple maps API to figure out how to get from here to here.

If not GPS, what does the FP use to determine its location?

I think it uses GPS. I went into Airplane mode - cellular off - and it still located and gave me directions. Anyway, I think the take-away is that elevation data is not available, but possibly could be used. Maybe in a future iteration.

To the other's point about "remembering" where you parked, yes, I get that. I typically take a picture using the phone of the location and the proper door, for example, at DIA. Years ago, would have to write things down, before smart phones with cameras. My point is that the technology is there to make it easier.....

Keep in mind that the app may remember the last place your car was located. Try shutting down the app for a day or so and move the car after you know for sure the app is not running. Put your phone in airplane mode first then start the app. There is another possibility the "cloud" keeps a record of the last location. I noticed in your picture that you had Wi-Fi turned on.
