Via-point recommendations?

Post by w2ge »

In the past, (say Mapsource years, older gps’s such as 550, 660) I religiously dropped via-points at true intersections (road and road), however with the newer generation of gps with the ability to set them to “not announce” on arrival (in BaseCamp), what Is everyone’s thoughts on the proper placement of viapoints?

I’ve never quite understood why some guys adamantly say the viapoints should NOT be on an intersection? :?: ; Other than sometimes I’ve noticed at a corner where there might be a quick left, then right, (etc) depending on my viapoints I sometimes get an instruction missing vocals for one of the turns...

TIA

For shaping points I place them wherever needed, without paying too much attention to them. For via points, which I only use if it's essential I visit them (eg fuel or food stop) I place them just before the actual point to give me time to slow down :D

lol, here we go with “nomenclature” ... what you’re calling shaping points I call viapoints, and what your calling viapoints to me are “Points of Interest“. Interesting and a good idea to place POI before the spot to give you time to slow down.

My understanding , routes shaped by:

1.) WAYPOINT: not a point of interest but I believe contains much of the same programming (vector data, mapset date, etc) *Announced by default.* I use mostly for start and finish.

2.) POI: restaurant, gas station, Scenic overlook that are included in NAVTEQ maps, etc.. *Announced by default.*. (I only use these at somewhere I want to stop at)

3.) VIAPOINT: like a pushpin, ‘pinning‘ your route onto a road and that your gps “wants” to go through(as in “via, this way”). Not announced if placed at true intersection, or can be made to not announce in BaseCamp, if it’s placed along a road... (I understand that now many call these SHAPING POINTS :? )

Back to original question, SUSS, so you place them anywhere (your shaping points), then set them not to announce? How’s that work with “turn directions” from gps?

Well it doesn't affect the turn by turn guidance as they aren't announced. For nomenclature here is the accepted definition:

POI - A formal Point Of Interest. An entry in the internal POI database with a name, location and usually other information associated with it.

Waypoint - Any arbitrary point on the map that you have designated you want to keep track of. Usually stored in the "Favorites" or "My Locations" or whatever your personal navigation device calls its waypoint storage database. Your device will usually allow you to store such things as the location, any arbitrary name you want to supply and other information such as address, phone number, category(ies) and a symbol/icon to be used when displaying it.

Via Point - A point used to create a multipoint route, e.g. Go from Point A to Point B via some other arbitrary point(s) that you will designate. If your personal navigation device supports multipoint routing, the via point can be a POI, an existing waypoint/favorite or any other form of location that is searchable on your device, e.g. address, intersection/junction, custom POI, etc. In most cases, to use something as a via point it must already exist in one of the devices' searchable databases. It will be announced when you reach it.

Shaping Point - In BaseCamp, to "shape" a route to go exactly where you want there are a couple of methods. Just as with the personal navigation device, you can edit the route's properties to insert Via points (these are not shaping points although they do serve a similar purpose). You can also just use the route tool to click on spots on the map to force the shape of a route. When you do that, you are using a location that is not already in one of the searchable location databases. BaseCamp does not force you to add these points to any of the formal databases. It simply inserts the actual coordinates invisibly into the route. These are shaping points. They are not announced when you reach them.

Shaping points occur in another, automatic, fashion as well. Even when you only designate a two-point route, e.g. go from Point A to Point B, there will usually be multiple places, usually intersections, where a change in direction is required. When building the route, the personal navigation device (or Basecamp) will automatically include all of these points in the route.

To easily illustrate this, you can create a two-point route in BaseCamp by clicking on a Point A and a Point B that will require a few turns to get from one to the other. Now export the route to a GPX file and take a look at it with Notepad or your favorite text editor. You will see that, in addition to the starting point and the ending point, there will be a bunch of other points <rtept> in the file to control all the turns.

Kk, thanks. Your final paragraph explains why after I create a route and look at properties I see what basecamp calls POINTS, (I never entered those, and never understood that “count”) and I also see in properties my waypoints, etc. are called viapoints. (What I entered).

Kk. Only been creating routes for >15 years and learn something new everyday.

Phil -

I too go back to MapSource days, but the devices have changed the way that they handle the routes. What used to work, I find is now causing problems in the routes.

I now place all of my points, Via Points and Shaping Points, just AFTER the turn. On newer devices, that support unannounced shaping points, it probably doesn't matter. But for Via Points, which get announced, if you place the via point before the turn, all of the directions and distances just before that turn will be to the via point, not to the turn. I find it distracting when I don't easily see what the next turn is and how far until I get there.

I also found for my 590, that placing a shaping point at the intersection of two streets does (sometimes) cause the distance to the next turn to be changed to the wrong distance while riding on the road.

I also found an issue with random straight lines appearing on the devices for my 450 and 550. This also got fixed by rebuilding those routes in MapSource and shifting the via points to AFTER the turns. This also required a recalc of the routes after they were imported to the devices. But once the recalculation is done the routes are correct.

Michael, SUSS...

Damn, this changes what I’ve been doing and always thinking (And teaching others) was a sacrosanct rule RE proper, clean route creation; that is ‘Shaping points at pure intersections‘.

Youve Blown my mind, I’m gonna need time to process this. :D :D :lol:

So, Michael do you go into properties afterwards and change your shaping points to NOT be ANNOUNCED? I want my voice instructions to be Clean and only announce turns and when coming up to a waypoint, poi, or ... via-point.

Phil - Yeah, I have had to completely switch my method of route planning. With my StreetPilot 2610, I used to put a point just before and then just after the turns. With the Zumo 450 & 550, I used to put the points exactly at the intersections. By doing that, they acted like shaping points and did't get announced. But, you couldn't ever recalculate the route, because all the shaping points would get erased and the route would just go from one via point to the other based only on settings in the Zumo. In my case that would change the route to the shortest path from the start to the end.

Now, I still use MapSource for the 450 and 550. But, I changed all the routes so the points are after the turn. But the 450/550 treats them as Via Points and they do get flagged and displayed (briefly) on the screen.

For my 590, I open the route in BaseCamp and make just about all of the shaping points Not Announced. All of the points are set after the turn. There's been a lot of discussion about issues with going off route and getting the device to direct you back to the route. This involves a balance between making a lot of points Via Points, or fewer of them and then having to figure out how and where to rejoin the route. It's a personal choice.
