Route Properties Incorrect Point Count in Summary?

I believe the top number is the number of instructions in the route, the lower number the actual number of points. But it's confusing I agree.

And whether it's meant to be that way I have no idea :confused:

Thanks.

It is confusing and funny trying to figure this out. When I look at the route directions window it has 60 Instructions (which includes 18 Via points). If I add the total instructions with the 39 via points from the route properties window that is 99 - getting closer. But 18 of those are counted twice. Hmmm. I get it! Sum the two lists, subtract the number of lists plus 1 = total points. It all makes sense now:rolleyes:.

So what I'm taking away from this is that the Total Points is some number not particularly useful.

It would be nice to see the number of via points less shaping points.

...Normally this would not concern me but I just recently picked up a Zumo 590 that uses Trip Planner, and is limited to 30 waypoints per route. Routes with more than 30 way/via points are split into multiple trips when imported to the device...

Don't think that is quite true as you have stated it.

More correctly you are limited to something like 30 ANNOUNCED POINTS (a/k/a Waypoints) In between each ANNOUNCED POINT you are allowed something like 29 to 125 (I can't remember the exact number) of UNANNOUNCED POINTS (a/k/a SHAPING POINTS)

I think BaseCamp will allow one to mark a point as unannounced and your 590 will honor that marking. If you are designing the Route on the 590 you can change the point from ANNOUNCED to UNANNOUNCED.

Go read through the 590 thread on AdvRider.com. Lots of good info there...

Huh?

You say: "limited to something like 30 ANNOUNCED POINTS (a/k/a Waypoints)"
I say: "limited to 30 waypoints per route"

I think we're saying the same thing.

And yes, the 590 is limited to I believe 125 shaping (non alert) points between each way/via (alert) points. But if the route contains more than 30 way/via (alert) points the 590 will split it up into shorter trips.

Basecamp does allow you to change a point to a shaping (non - alert) point in the route properties window and the 590 recognizes this feature. That's not my issue though.

I often download routes that others have created that contain a lot of way/via (alert) points. What I would like to be able to see is the number of way/via (alert) points only. Route properties only shows the total combined way/via (alert) and shaping (non alert) points.

I was just reviewing a route through Acadia Nat'l Park and around Mt Desert Island. The route has 200+ points. Almost all of those were way/via (alert) points. After changing all the obvious ones to shaping (non alert) there were still a lot of way/via (alert) points for stops. When I imported the route into the 590 it split it into two routes. Oops, too many way/via points still - turned out there were 41. Just saying it would be nice to see that in the summary.

I’m reluctant to chime in here since I don’t own a Zumo, but I think you may be overly concerned about type of point (waypoint/via/shaping) and alerting/non-alerting.

Historically, Garmin has provided two point limitations for routes. One is for Direct Routes and the other is for Automated Routes (anything that isn’t Direct). These numbers refer to the total number of user entered points. These are the points on the Route Property page and this number is always the Via Points in the summary information.

I suppose it is possible that the maximum number of allowed points in a Direct Route could also be a limit to the number of turn by turn instructions allowed in an Automated Route. This may be what the Points number in the summary refers to, but how they are counted I have never figured out. After looking at several routes, I have never been able to make the numbers add up for all routes.

This is a case where thinking like a human fails. The issue is one of programming limitations, whether it is related to memory allocation, total number of actual points in calculated routes (there can be thousands when you include points that make up the line on the map) or perhaps something else.

What happens when these limitations are exceeded will likely depend on the device. It is pretty much left to users to experiment with their devices as I have never seen a clear explanation. If you like to play around, I can think of three possible limitations: 1. number of user entered points for a route type (Automated/Direct); 2. number of turn by turn instructions (related to maximum number of points in a Direct Route?); 3. total number of points which would include all the points in a gpx file for a route (you can get an estimate of this number by opening a gpx file of a route with Excel). The routes will have to be sent to the device and activated to test what happens.

BTLAAKE:

I'm not overly concerned. For newer units that use Trip Planner it does matter.

The Zumo 590, like many newer units that use Trip Planner, is limited to 30 waypoints per route. This limit does not apply to "user entered points" - it applies to any points in the route that alert (via). It does not apply to user added points that do not alert (shaping). That's just the way that it works. Really, I'm not making this up! It's in Garmin's support literature and I have confirmed it with my own use. There may be other limits that apply but I'm not concerned about those, I've never run up against limits on any of my previous units.

If there are more than 30 waypoints that alert in the route, Trip Planner in the device will split the route into multiple trips.

Basecamp has a great feature in the Route Properties window that allows a user to set any waypoint to not alert, basically making it a shaping point. The Command is "Don't Alert on Arrival (shaping point)".

Since the Z590's (and many other units) routes are limited to 30 waypoints that alert (or viapoints or user entered points, whatever you want to call them) it would be nice to see the number of via points that alert in the route properties window.

I agree, we were saying the same thing, Breezly. But, I wasn't certain you were aware of the ability to have many points between the waypoints.

One out of the box type solution to routes having too many points is to convert many to POIs and set them to alert based on proximity. One can also add custom symbols to those points (On my Nav-V most points have that darn heart symbol). As long as the route gets near enough to the POI to cause the alert they will just about fulfill the usual waypoint functions. Since the number of POIs is unlimited for all practical purposes and because they don't count against your route limit you will still have a single route. You might also just consider making them waypoints and set proximity alerts, should work if you aren't concerned about the symbols.

I did the save as POI with custom symbols and proximity alerts on my last big trip where the original gpx file I purchased had over 750 waypoints whose symbols carried a lot of information.
