Multiple alerts for POI Factory speed camera locations

 

I frequently pass a pair of speed cameras, one pointed each direction on the two-way street. I begin to be notified at the appropriate distance before the first one (the one I need to worry about), but then receive FIVE MORE notifications (three per camera).

Is there a simple way to sort the .csv file to see if there is an extra set of coordinates in there? I'm not an Excel wizard and a scan for the street name turns up only a single location in that block.

TIA.

.csv files

I use note pad to edit these type's of files, you can view the file and see if there were multiple entries and delete them . make a backup of the file first !!!

Never really thought about it

but maybe has to do with the speed at which you approach the intersection? I would have to check it but if you are approaching at very slow speeds (heavy traffic)you get more alerts? An option is to delete that camera from the file since you know it's there. It's really simple.

Duplicates

Download ASAP utilites http://www.asap-utilities.com/download-asap-utilities.php the Home and Student edition for free.It works with Excel.Great program with easy shortcuts. Once downloaded highlight columns A and B.Then click on ASAP utilities,top right. Select (5)range and scroll over to (22)count duplicates and give each set of duplicates its own color. Once you click on it follow the instructions. Now you can look over the duplicates. This program helps a lot when doing files and etc.

Since you are a long time member, I am going to assume that you do not have multiple copies of the speed cameras loaded. This is reinforced because it seems that you are speaking of a specific pair of cameras in the DC area (which is where your profile places you). Nevertheless, you might check to make sure that there are not multiple .gpi files (with slightly different names because with the same name on the input file POILoader would ask for instruction).

I would open the "Speed-Cameras.csv" file using EPE. If you have never used it, then read
Downloading and Installing EPE {G}
and
Configuring EPE {G}

Use EPE to open the "Speed-Cameras.csv" by
File > Open and navigating to the file.

Then, do
Edit > Find and enter the street name where the camera is and click Find.

This should bring up the first of a match on the street name. If that isn't the one you want, then use F3 to find the one you want.

Then, do a Tools > Sort By Location and the file will be sorted in order of distance from the camera that you found.

Now, you can inspect the first two entries by left double-clicking on the first one and you will get the "POI Edit" dialog wherein you can inspect the coordinates. At the bottom right of this dialog is the "Next POI" button to look at the next closest POI.

Alternatively, if you wanted to see if there were "Duplicates" in the file, in EPE you can - from the main screen (not the POI Edit dialog) - do a Edit > Find Duplicates to get the "Find Duplicates" dialog. Selecting the "exact match" option on the most recent camera file gives us Medina TN (but your profile says you are in DC) so I do not think that is the one.

Using a distance of .02 miles, there are several in the DC area that strike me as being within 30 meters of the "road" to trigger a second alert, but not the multiples you report.

As has been suggested, having to slow under a certain speed often regenerates an alert - but you are saying specifically there are a total of six alerts.

I do not know if you have had someone closely look at the "alert" ovals, but if you have, we would be interested in what they say.

We would be interested in what you find out.

Delete Entries

This is what I do.

Try Google Earth

When I started I took the GPX version and saved as a KML file. Then open it in Google Earth and the check the intersection or any other POI to see if more than one POI is there. If so then with EPE you can delete the duplicates. This will find dups with a slight difference in coordinates.

POI Loader

Will the POI loader export files from the GPS in CSV, GPI and GPX format?

Poiloader

When you run Poiloader on your computer with gps connected . It takes your csv and gpx files and converts them to a gpi file to your unit. The file can be found in the POI folder on the GPS. Look for the extension gpi with the name of the main folder for your custom pois.

POI Loader

POI Loader is a one-way program in that it reads source files in either a fixed CSV or GPX format and converts them to a GPI file stored on the unit. POI Loader will not read or transfer from the GPS to a computer or other device.

I had to reduce the alert

I had to reduce the alert distance to less than 500' on mine because I was getting alerts about cameras on other corners in the city. U may have the same issue if there r cameras like one street over.

Don't often get this chance

I do not often get a chance to quibble with Box Car as he is usually spot on.

His first sentence is spot on.

However, while I was framing my post above, I attached my 765 to the computer. I fired up POILoader and pointed it at the Garmin\GPX folder of the 765 and told it to put its output file on my computer.

POILoader found the "current.gpx" folder in H:\Garmin\GPX and happily created a GPX.gpi file in C:\User\Garmin\@@poigpi on my computer.

Assuming RLC

I do not have enough RLCs where I live such that they are within 500 feet of one another so I can not check this out. However, if this has occurred to you I find it very interesting.

Seems to me that we are talking about either "along the road" or "along the route" as far as "alerts" for redlights are concerned. If one just loads our "Redlight-Cameras.csv" file using POILoader, a default proximity alert distance of 400 meters/0.25 miles (1320 feet) is created because the file name contains the word "redlight".

For an alert to occur, the coordinates of a RLC must be within 30 meters/98 feet of the "road" or "route" along which one is traveling - the difference being that a "route" would let one turn onto a road OTHER than the one currently being traveled as far as the "distance" calculation is concerned.

I do not see how a RLC one street over could activate an alert unless the "route" involved taking either two consecutive right turns or two consecutive left turns - resulting in the route passing by both cameras.

Speed cameras

The OP discussion is about speed cameras. Some of them have the @ with the speed and some don't.

Perhaps I should have been more specific

Perhaps I should have been more specific in stating POI Loader will not transfer from the GPS to another device in a format that can be edited by the user.

@Box Car - that is correct.

I was trying to understand exactly what can happen if one does not follow the "normal" sequence of events we expect of someone working around with .gpx files.

Most of the time we would expect someone to put a .gpx file into a folder on their computer as opposed to putting a .gpx file onto their device. However, users have learned that putting a specific previously saved .gpx file onto the device itself is one way to restore "Favorites" after having done a Master Reset. Sometimes, however, people have put a .gpx file onto the device expecting that the device would place the entries in that .gpx file into their "Custom Pois" of their device which does not happen - rather putting the entries into "Favorites/Saved Places"

After your comment, I got to wondering if I could convert a .gpi file back to a .gpx file in a fashion that would be of some use to me.

So, using the Jo-Ann file that I maintain I created, using POILoader, a Joann.gpi file on my 765 in H:\Garmin\POI\Joann.gpi which had 851 entries.

Based on the thread http://www.poi-factory.com/node/44626, in which Charlesd45 had suggested http://www.gps-data-team.com/convert.php,
I rather went to https://garmin.gps-data-team.com/poi_manager.php which offers to "Select your TomTom OV2, Google KML, Garmin CSV, Garmin GPI file, Nokia LMX, XML GPX or Navman CSV file" for upload.

Then I pointed to H:\Garmin\POI\Joann.gpi as the "Choose File" and let that file "Open".

On the screen https://garmin.gps-data-team.com/edit/poi_manager_online-25_...
at the bottom I saw
"SAVE AS: CSV OV2 GPX GPXx KML LMX Refresh"
I chose the "GPX" option and saved the resulting file on my computer. I then chose the CSV option and saved it also.

I used EPE to open both of these files and indeed they are my JoAnn file with one additional entry (852 rather than 851 entries as it should be). If, however, the last line is deleted, I have a semi-usable file.

Everyone should be careful with "gps-data-team". A number of their options do not work - but right now, https://garmin.gps-data-team.com/poi_manager.php seems to be OK if the .gpi file is less than some size (what I do not know).
