Changing distance in speed proximity

I assume you are using CSV POI files. You could convert them to GPX. GPX files let you set the distance as well as the speed independently. You can set the speed either with or without proximity or proximity either with or without speed alerts. These are set once in each POI entry as you modify the file then you use POI Loader's Express Mode to load the files onto your GPS I use GeePeeEx but there are several good programs that will convert CSV files to the GPX format.

Good luck

If you are looking at getting around running poiloader in manul mode for some custom pois you can use the rename method for pois that don't require a lot of update http://www.poi-factory.com/node/8779 .Also you can use Extra Poi Editor to build the alert distance in and use express mode.Here is how.

You can download Extra Poi Editor at http://turboccc.wikispaces.com/Extra_POI_Editor and build the distance in for the alert. When you download the program if you get message about OCX file missing scroll down on the main page and under troubleshooting you will find the Extra Poi Editor Installer that you will need to download. Once installation is completed you will need to set up the preferences you want first. Under options click on preferences. For example using ft for input. Under units you will see editor, select Imperial/US. For Field Read select metric and Field save select Metric. After setting your preferences click on file and click open to select from your computer the file you want to build the distance alerts for. Then go to edit and click on replace field. Once the next screen comes up use the down arrow for Field name and pick proximity. Under new field value put in the distance in feet you want for the alert. Then click replace all. You now have distance set for each custom poi. Then save as a gpx file. You will lose the built in alert if you save as a csv file. The nice thing about this method is that you can use express mode for poiloader.

I have been trying to figure out how to set the proximity in the extra poi editor. Your explanation made it quick and easy.

Thanks Again,

Once I converted all my .csv speed traps into .gpx, how do I set the speed and distance without having to manually change it each time in POI loader?

See my post above for alerts on building the distance in gpx file.Same method for building the speed in.

With certain key words in the file name alert will be automatic.Speed sets off a 1/4 mile alert distance.

This is some information from the help tab on poiloader.

If a file name contains a valid speed number or if all records in a file have speed encoded in the name, then all records in the file will include speed and proximity alerts. For example, a data file with the file name "Speed_30" generates speed alerts of 30 mph (or kph, depending on the type of units selected in POI Loader) for each POI in the file.

If the file name contains "redlight", POI Loader assumes all records in the file have proximity alerts with a distance of 400m/0.25 miles.

If a file contains "GATSO," "mobile," "SPECS," "safety," "speed," or "camera," but does not have a speed, POI Loader uses a default alert speed of 0, which means you will always be alerted. You can override this default value by entering the speed in Manual mode.

You can also enter speeds for each POI individually by adding the @ symbol and a number after the name of the POI. For example, a Custom POI named "Ridgeview@25" would create a POI named "Ridgeview" with a 25 mph speed alert.

POI Loader calculates proximity alert distance based on speed. You can enter proximity alert distance for individual Custom POIs in a .gpx file. You can also enter proximity alert distance for all Custom POIs in a data file using Manual mode.

If you are using Extra POI Editor it's a simple process. Press Ctl-R and bring up the replace field box. Press the 'P' key until Proximity shows in the box, tab, then type in the alert distance. Tell it to replace the field and then confirm. All done.

The same process works for speed but be certain speed shows.

I'm not clear on the last part of your statement. "POI Loader calculates proximity alert distance based on speed. "

Do I enter both a Prox Alert and a Speed Alert?

If so does this cause the Prox Alert to increase if your speed is higher than the Speed Alert Value entered?

Distance alerts are distance alerts. They don't change. A speed alert is different. It will trigger at a distance calculated by your current speed. That distance is equal to the amount of ground you will cover in 36 seconds before you reach the point.

You can set both speed and distance alerts but they are a little tricky. If you include a speed in the file name of a CSV file such as School Zones 20.csv you will get an alert based on your current speed 36 seconds before entering the zone. Because you are going faster than 20, the alert will repeat until you are at or below the default speed in the file name. Now, if you are extra paranoid, you can also set a distance alert using the proximity settings of either POI Loader or EPE if you use GPX. (And if you use GPX you can set both alerts and not have to include the default speed in the file name.)

This is great. I never really understood speed alerts before.

I created some Red Light Camera Alerts for my city and just used Prox Alerts. I'm going to test this. It also seems a better way to set Rest Area Alerts.

I was wondering why there were 3 files in the red light camera download package with duplicate camera locations.

Are they written for different warnings/distances/speeds so you get multiple alerts for each?

You'll find your answer in the explanation Charles45 provided a few posts back. Since the word "redlight" is in the file name of the 2 redlight camera files, POILoader will load them by default with a fixed 1/4 mile (.25mi) alert distance, no speed factor involved.

Since the word "speed" is in the file name of the speed camera file, POILoader will load them by default with an alert speed of 0, which means you will always be alerted.

When I load the redlight and camera files, I change nothing. I load them both using the default values. In this way, I get an alert 1/4 mile away from a redlight camera and an alert no matter what speed I am traveling as I approach a speed camera.
