Doted lines outline what?

[Acemac]

any one have any idea what the dotted lines mean on lake maps below is an example.

here is a better example as i think the first pic is outlining a fishing spot.... how they figure that is the bass spot i would like to know?

[TooTallTom]

You've got me. Is there any sort of help file you could search? It seems like they're trying to help you out with something here, so they're probably pretty proud of the work they've done...

[goblueM]

those are the paths of the boats that will zoom around you when you're trying to fish

[mr.z 1972]

Those are the recommended trolling routes.

Hmmm, that second one is just wierd.... survay paths? There has to be somthing to tell you what these are, now I really want to know.

I think they are outlines of different bottom/or weed types....some dnr maps have that, but usually have abbreviations also.

I was actually thinking something like that, that they *should* be bounding some kind of homogeneous area, and that maybe the labels were just off because the scale was too small.

The outlines in the second screen capture remind me of a soil-types map from NRCS...

[Ed Carlson]

What map source did that come from, that may help too?

It looks like Navionics on a smart phone.

I was wondering yesterday, what's the record for replies to a posted question WITHOUT any actual answers?

I believe this response was the correct one

These lines are on DNR maps for two lakes I fish. On those maps they denote bottom composition... on the DNR they're labeled. In the Navionics program on my Droid, the dotted lines are still present however the labels are gone.

[Ed Carlson]

Darn it....I was betting on WaterBug migration patterns myself.

[fishwater]

I know on past version of the navionics maps for the St. Croix river, there used to be lots and lots of denotations and hashed lines denoting features. Saugers here, bluegills there sort of deal mostly, but other odd stuff I never figured out. I know the much of it has been removed in recent updates.

The top pic does look as though it could be a trolling pattern,It hits the spots I'd likly go to.The bottom one is confusing???

[Hawg]

I bet my answer is the right one. You have a bad app. It's new isn't it? I bet it's just plain screwed up. I'm going to watch though because I want to get it also.

[CAMAN]

The top one is unclear, but the bottom one is infact bottom content. Those lines are on numerous dnr maps, their just usually labeled on thednr maps.

[sticknstring]

Skimming the Navionics post in the ice fishing forum the other day, I remember hearing about map gridline overlays. Whether or not that was v 4.3 or the newly updated 5.0, I don't know. I just downloaded this app this morning and haven't played with it enough to find out for myself.

It's the path that the guys with portables use to try to move in on permanant houses

Bottom is for the advanced trollers. Stick to the top one for now.

[jBohmer]

Bump this up! I cannot beleive anyone here has not come up with the "for sure" answer yet. I am very interested in this and I do not even have a GPS.

[My_Key]

Do they guarantee the bass will be there? I see a lawsuit for false advertising on the horizon..................

If people can win lawsuits for driving off the road because the GPS on the dash told them to, anything is possible.

If I get my portable set up next to your perm before you get there for the day does that mean your the rude when you finally get there?

[Surface Tension]

Q. What does it mean when a Track appears as a dotted line and not a solid line?

A. In areas where GPS signal is poor or absent, recorded Tracks appear as a dotted line. This means that the GPS signal has little or no strength.

That might explain the top picture but not the bottom picture.

[Ed Carlson]

OK, my best guess is Navionics will use multiple forms and sources of data to build these lake maps. DNR, state, upgraded on the water surveys. So what I think it is was some left over survey junk data that was later updated with an overlay but not fully omitted, just redundant data. No reason to be there, just is.

Early surveys with boundary's now long forgotten...just a best guess.

It may go away if you change the detail setting and not diminish the mapping?
