Sure, just hack into the programs and figure out how to bypass the way it's keyed to the unit's serial number then you can use a copy of mine. :laugh:

Yeah, I know.... just wishful thinking... I thought there might be a way for a 3rd party to build a routeable map for these units. Maybe in the future.

I don't think so Denis, the only way I can get my 710 to calculate a route is when the "City Series' map is activated. Either USA or NA.
When any other detail map is activated I get no routing.
When either 'City Series' is checked no other detail map can be checked.

Street data... Is that like, "Routeable Map" kind of data ? Hmm, possibly an alternative option to the NA Magellan Street map ? I'm interested in Canada..... 😉

Jamie,

no, no. I understand your intention to understand where the difference comes from. And just wanted to point out where the difference in the topo information comes from, as I presume most of the users here are not really aware of this.

As for the trails, please post which areas are not covered enough/correctly and I'll do my best to get the respective data, as I am currently working on the new maps for USA (2010/2011 Street data was currently published by the Government)

I hope I've in NO WAY offended you at all...not what I intended what so ever. I REALLY appreciate all that you have done for us even going so far as to set an excellent site for download of all the data that you've worked on. I was just talking in general about what I've seen and am trying to understand what's going on. From some of the shots phild31 has posted that looked really good I've just not been able to duplicate it and like you said...states are so huge that it's probably just due to that fact of the things you have mentioned. You are and have done an EXCELLENT job and major kudos to you for a fine job when you didn't have to do anything for anyone.

Also, thanks for taking some time out of your day in replying to all the messages. That's quite a personality to maintain a humble response to any/all comments that might seem like criticism. Thank you for being who you are.

Jamie

Thanks for this... 🙂

I do not spend any money for data. I am only using 100% free data. But with the trails of the USA is is a matter of time you are able to spend, because if you find a good piece of data (e.g. for a national park) this data will overlap and you will start building a layer by patchworking data, searching for duplicates and manually adjusting... and the States are huge... 🙁

Best regards,
Sockeye

The topo lines of the Terraserver maps is the most accurate information you can get.

Vector maps contain a DEM (digital elevation model). As the maps where designed for the Triton series, the embedded DEM has a spartial resolution of 3 seconds. Which means it stores one height point for every square of 3 arc sec x 3 arc sec (eqv 90m x 90m ~ 270ft x 270ft) This means in the worst case, a 269 foot wide canyon may not show up at all. The map engine now calculates the topo lines dynamicly. Displaying contour lines for the calculated difference between two points stored in the DEM.

Now the explorist units can handle 0.9 arc second data (~ 80ft x80ft) DEM data which is included in the Magellan Topo DEM. But this also results in filesize. The USA DEM takes about 1.2 GB data. But the result is more accurate (still having a worst case error of 79 feet)

I hope, I could explain the possible differences between hand-drawn topo lines on raster maps and calculated topo lines coming from a DEM.

Best regards,
Sockeye

Good, I'm glad you figured it out.
I've found some trails in western Mass that showed on the Maps4Me but didn't show on the Summit.
I guess it depends on how much detail is available in the source data the map makers use.
But I imagine Magellan has more resources to use and money to spend while making their maps than Sockeye does.

But I love your maps Sockeye, you're doing a great job with them. :woohoo:

OK, i think I finally got it worked out. I had three Maps4Me maps downloaded. In addition to the North East I also had NC and GA. When I unchecked the NC an GA maps the North East topo lines appeared along with a few ski trails including the one you showed on Sugarloaf. The map still does not show the trails that the summit map shows, but I am pleased to now get the topo lines.

I have never liked the Terraserver maps very much.
The Summit topo is what I usually have activated and I'll switch between Maps4Me, Summit and Jungle Ghost's topos to see what map gives me the best detail for where I'm at.

Like Sockeye said, the detail available in different areas is not standardized at all.

For not getting details with the Maps4Me, try checking what background map you are using?
When I use the World Wide Map I get all the details on the Summit and Maps4Me detail topos.
So just make sure the MITAC World Wide Map is selected.

The World Topo Basemap is from Jungle Ghost and I will get details on only the Jungle Ghost detail maps when I use it, no details on Summit or Maps4Me.

With ONLY Maps4Me Indiana area with what I know is VERY steep terrain

And with Terraserver at the same scale and section

I can't say that I've noticed it before either (mainly because I use my own Topo's from MOBAC and Terraserver) but I cannot get the topo lines to display. I have also checked and even toggled the 'shaded' & 'topo' settings and still not able to display them at all???? Only shaded relief is displaying for some reason. Hmm....wonder what's going on? I have disabled my 'image' maps so that shouldn't be an issue...

EDIT: Hmm...ok...so I have about 5 states downloaded into my unit and after disabling all of them by my home state of Indiana the Topo lines finally display....and WOW...what a difference I've just noticed. I've taken 2 screen shots from the EXACT same area and although I REALLY like the Maps4me maps for the HUGE level of detail for just about everything I gotta say something doesn't seem right. Compared to Terraserver maps the contours seem WAY off.... I'll try to post some pics...

Then Terraserver

Trail data for the US is a mess. Every government / state / community maintains their own data.

But as I am currently working on updating the maps, please address requests now and then I can go hunting for specific data for specific areas, which is not covered yet.

It would appear from what Phil says that the Maps4me have what I'm looking for, but for some reason the detail just doesn't show up in my GPS.

On my eX 310, the only way to get contour lines to show with the summit maps is to toggle the 'Shaded Relief' on and off. Each time the unit is turned on there are no contour lines. If I go through the 20+ clicks to cycle the shaded relief they will show. Of course then its time to replace the batteries. In my case the maps4me maps work just fine.

Phil

I just checked. My settings are exactly as you indicated and my summit maps are identical to yours. However, the maps4me give the summits only, the background is brown and there are no other details. I would love to get the detail you show.

Check the settings under 'Map Options' -
'Map detail' - High
'Topo Lines' - On
'Shaded Relief' - Color and Shade

You'll also notice the Maps4Me map shows the same geocache 100 feet lower than the Summit map shows it.

They show fine for me.
The trails don't show the same on the Maps4Me as the Summit.
These are Sugar Loaf trail near Twin Mountain, New Hampshire.
Here's 3 Summit shots;

And 3 Maps4Me;
