red light cameras

 

Just a general question on red light cameras, why would you get a warning signal on the GPS going North or South, but not going East through the same intersection? This is the POI Factory file.
Thanks (This is a very good web site for information)

Good Question

I think the answer will be that the coordinates of the camera will be "on the route" of north/south.

However, I wonder what would happen if the coordinates of the camera were dead center of the intersection? I will have to try a simulation of that.

Which camera?

Can you post which camera POI it is from the file?

The POI Factory red light camera file will give a proximity alert no matter which direction you approach from.

The location of the coordinates for red light camera POIs is the same as for any proximity alert - 50 feet to the right and left of your track ahead. (some have said possibly up to 98 feet to the right and left of your track ahead) Think of the alert area as a rectangle with a width as described above and a length equal to the proximity alert distance you entered in POI Loader.

I always try to place coordinates at the dead center of the intersection, so any car approaching an intersection of two streets each 100 feet wide would get a proximity alert.

on highway

many times, I get alerts for red light cameras on nearby surface roads when I'm on the highway. I ignore them, but first I have to look at the gps. kind of a pain, but I don't want to complain bec I appreciate the effort people are taking to keep files up to date for us.

POI Update

I just finish update the Rest area and the red light e speed camera on my Gps and I use the POI loader..I notice that when I use the POI loader does not show me the files inside the folder I was reading an article here about this that also describe the same problem, using the POI loader to my opinion is not the best thing to use.infact I hand up with 2 version of REST area and the same it go for the camera..If poi loader does not show the file that I have then you do not know what to delete and what to keep..I would like to know instead me using the poi loader ,what about if I do a copy/paste of those files on the poi folder..At list it show me the file version and the date.Also like to know on my garmin they are 2 folder one is called POI and the other GPX. What files go on the gpx folder ?

What?

What version of POI Loader are you using? POI Loader is the program which reads GPX and CSV files and then compiles those files into a GPI file read by the unit. GPI files are in the poi folder.

POI Loader loads whatever is in a folder that you tell it to load. The folder can have CSV or GPX files as well as one level of subfolders. To paraphrase Capital One, "What's in your folder?"

What problem are you having? Try writing down the steps you are following in loading the files and we'll see if we can tell you what needs to be corrected. You need to be clear and detailed about the steps.

How many GPI files do you have in the poi folder on your unit? What are their names? Did you rename a file or tell POI Loader to name its file something other than POI.GPI?

The GPX folder normally holds a list of your favorites and any locations you have sent to the unit from programs such as Google or MapQuest. Depending on your unit there can be other things such as routes you have created and sent to the unit. You normally don't put files into this folder, but you do need to clean it out from time to time if you have been sending a lot of addresses to the unit or creating a lot of routes.

Use POI Loader

It is normal for POI Loader not to show the files inside folders. This is not a problem. Copy and paste will not work. Run POI Loader using this FAQ -

POI folder

Box car thank you to answer to my question..On my garmin I have a folder called POI.and I was adding all the file into that folder ,From what I reading inside that folder I suppose to Create others folder and name them like speed camera and create more folder like Rest area and then add those file in to the proper folder..

Thank you for your answer..and please confirm if that is the right was to add poi files..
Thanks

Folders and more folders

If you use folders to organize your POI you would normally have a top-level folder - you are calling it POI. Inside that POI Folder, you can have up to 32 additional folders, but those folders can only contain files. You can't put another folder inside a folder that is inside the POI folder.

In each of the subfolders, you can have 32 files that's CSV or GPX files. The BMP and sound files don't count.

You don't need a separate folder for each file, group them together. As an example, I have 3 folders for food, 2 for restaurants and one for fast food. I also have a folder labeled Fuel Locations. I put all the fuel stops in this folder. Another folder I have is "Stuff" that's where I put the time zone file, state lines, speed and red light cameras and other "stuff" that doesn't fit in one of the others I have set up.

The way we use our units is probably quite a bit different, and I load almost exclusively GPX files so I can build speed and proximity alert distances into the file. That way I load everything using express mode. Takes about 2 minutes to load over 150,000 individual POI.

Red Camera

This file may not be perfect, but it is the best one available. I also appreciate the effort and time that goes into creating this file.
