Re: Maemo Mapper v2.0
 

Greetings:

I have Maemo Mapper version 2.03 on my N800.

There are so many features with this version.

I really enjoy the totally black screen when I view the maps.
Also the apps keeps on stating that "downloading maps failed"

So it seems for me a black screen is what Maemo Mapper is all about.

Thankyou for helping out.

Regards Robert

Re: Maemo Mapper v2.0
 

Scratch you map repos, download them again, if you still get downloading maps failed then switch to a non-google map repo (their servers seem to automatically blacklist your IP after downloading a certain amount of maps). Works For Me (TM).

Re: Maemo Mapper v2.0
 

Are you sure, or is it just that google doesn't have what are now zoom levels 0..3?

Re: Maemo Mapper v2.0
 

After a bit more playing, I am stunned at how good V2 is. Seems stable too. gnuite, I want to have your children!

Is there any way to change the logging of a track to equal intervals of distance instead of equal intervals of time?

Re: Maemo Mapper v2.0
 

If you meant what I said about maps apparently been blacklisted from downloading, then no - this happens to me when I'm zoomed way out, it's enough that I have started goofing around for a while. In fact when I first tested 2.0 I thought those maps were just offline, until I found I could successfully download them when I moved to another internet connection -- for a while. Until it started failing again.

Re: Maemo Mapper v2.0
 

Okey, this is rude.

There are hundreds of people who had successfully using this software, if it is not working for you then it is your problem. You have to fix this on your own or request help from others. You have no right to make humor about this software.

Re: Maemo Mapper v2.0
 

Make sure you're holding the stylus down hard enough. If not, and Maemo Mapper thinks you're tapping on a single location, then it will center on that location. If the single location is on the right side of the screen (during a drag-pan from left to right), then Maemo Mapper will pan right instead of left.

Re: Maemo Mapper v2.0
 

It should all be fixed now.

Re: Maemo Mapper v2.0
 

In the "Manage Maps" dialog, use the "Along Route" option instead of the "By Area" option.

Re: Maemo Mapper v2.0
 

It sounds like you need to purchase the Navicore add-on if you want a mapping application on your Nokia device. Or, you can buy an N810. Either way, Maemo Mapper does not appear to be for you.

Re: Maemo Mapper v2.0
 

Google supports zoom levels 2 through 20. Attempts to download maps at zoom levels 0 or 1 will fail.

Re: Maemo Mapper v2.0
 

Not sure what you mean. Are you referring to the saving of the track to disk (which occurs once every minute), or to the actual track points that are recorded?

Re: Maemo Mapper v2.0
 

I'll be honest. When I first got my N800 and downloaded MM i didn't get it either. I thought a blank screen was all it was too (well maybe the map of the entire US of A). So I kinda understand this fellows thinking though I wouldn't have posted it here in the manner he did. It was really by accident that I hit the zoom key and figured out what was going on.

Perhaps there should a be quick "set up" screen or something that kind of points total noobs in a direction to get up and going in the most basic way and have that screen only appear the first time the app is run.

Just a suggestion.

Re: Maemo Mapper v2.0
 

Aahh explains my DL problem last night.

Re: Maemo Mapper v2.0
 

Here's a dumb question - but if I use winmapper to download the maps - where do I put them with this version? All I see isa Cache DB that appears quite large. I have managed to move that db to my MMC, and edited my repository to point there, but not sure if I have switched the application to use my MMC.

Re: Maemo Mapper v2.0
 

Two things here, first the 2.0.3 version has fixed my issue with the GPS connectivity!

Second, as I played around with the new POI feature, I suddenly have lots of purple square POIs on my maps. Soooo, would it be easy to have a feature in the Edit POI Category box to allow users to determine each category's POI color? I think that would help differentiate the different POIs as you drive near them.

Re: Maemo Mapper v2.0
 

Ah, ha! Thanks! Man, that's going to take a while. :( 3,775 miles.

Re: Maemo Mapper v2.0
 

gnuite:
When I record tracks on my handheld Garmin, I have the option of recording track points at equal time intervals or equal distance intervals or a magic in-between formula. The equal distance intervals option would be handy on the n800 if I wanted to create a road map by driving around (which I do).

I didn't actually check the n800 gpx track files before I posted my question. I can now see that the track points are recorded every second. This is frequent enough that I can probably create a derived track file with points at equal distance intervals using gpsbabel.

Is the one second between track points a fixed interval, or can it be changed?

Re: Maemo Mapper v2.0
 

When I did my NJ to Miami trip I downloaded maps while at hotels. Had less errors that way especially for multiple zoom levels. Like I only wanted level 6 for between stops. but I wanted 0-3 for the locations I was stopping in.

Re: Maemo Mapper v2.0
 

Winmapper does not (yet?) work with Maemo Mapper v2.x. It relies on the old 1.x method of storing maps.

Re: Maemo Mapper v2.0
 

You can customize the look of POIs by using PNG or JPEG icons. Simply place an icon file in the same directory as your POI database file, where the filename is the same as the name of a POI category or the label of an individual POI, and give it the "jpg" extension (even if it is a PNG). Maemo Mapper will use that icon instead of the purple square. See this ITT thread for more details, or search the forums for other icons.

Re: Maemo Mapper v2.0
 

It depends on your GPS receiver. Maemo Mapper does not use an interval. It draws data (and records track data) as soon as it gets it from the receiver. Maemo Mapper does discard some data from being recording in the track file, but only if you haven't moved since the last recorded track point.

Re: Maemo Mapper v2.0
 

This is really outside the scope of maemo-mapper, but I'd be interested in what people think.

Maemo-mapper, GPS and Google Earth are now so good that we can see errors in some of the data available. In Trinidad, I can consistently see a 15m offset between GPS locations and Google Earth/Maps data. For instance, the attached file shows a track I drove this morning plotted on Google Earth (I see the same offset on the n800 when I use Google Maps). There was very good visibility of satellites, so the error in the location should be less than 5 metres.

I have noticed a similar, much larger, offset for Dominica using a handheld GPS: 150-200 metres. I posted to the Google Earth discussion forums, but never got a reply.

Data providers like Google do not seem to provide quantification of the accuracy of their data.

How could we improve the situation:

a) Feedback to the map providers
b) Create our own versions of map files, shifted as we see fit.
c) An option in maemo-mapper to shift map data by a user-specified amount.
d) Shut up and be happy with what we got.

Re: Maemo Mapper v2.0
 

Thanks for the info.

Re: Maemo Mapper v2.0
 

That would explain it.

So by setting the cache to my MMC, I effectively am using the MMC for storage? I noticed Maemo Mapper crashing when it rans out of space on the internal flash....

Here's a side question - does Maemo Mapper have the ability to recompute my trip if I go astray?

Re: Maemo Mapper v2.0
 

Hello -

I don't usually join forums (just read them). But I wanted to join to let Gnuite know what an awsome job he has done with this software.

I also have a question: I use the 2007he on the N770 and I was wondering if anyone has any optimal settings to use with 2.0 as I have noticed that it is not as fast as 1.X. I realize it's probably not going to be as fast, but now my blue dot ends up off the screen alot while the software tries to catch up. It used to stay in the middle before.

Re: Maemo Mapper v2.0
 

Does a downloaded route plot with the same error as your track? If so, then it's possible that the lat/lon-to-screen conversion code is not accurate. If I may ask, in what part of the world was that track recorded, i.e. far north or south, near the equator, etc.?

Re: Maemo Mapper v2.0
 

I believe (haven't done formal testing) it's slightly faster if the view is not rotated (i.e. north points up) and when you are at a zoom level for which you have maps in their native resolution (i.e. not pixellated). Also, your memory card read speed will have a direct impact on how quickly Maemo can render the screen, so you may want to invest in a faster memory card.

Other than that, the only thing you can do is enable Lead centering and/or zoom out so that refreshes are not as common.

Re: Maemo Mapper v2.0
 

Darn. That use case is so hard to test on my desktop! I'll see if I can fix it by testing with the file read-only. I would have thought that it would have just produced an error (just like when you're disconnected from the internet).

If you have an internet connection, then yes. In the "Download Route" dialog, enable the "Auto-Update" checkbox. Maybe I should re-word that to "Auto-Correct" or "Auto-Recompute" or something more intuitive....

Re: Maemo Mapper v2.0
 

My routes and plots are pretty much spot on up here. I have seen them drift when I don't have a good gps fix though.

Re: Maemo Mapper v2.0
 

Just out of curiosity : Pymapper (http://www.internettablettalk.com/fo...ad.php?t=10185) allows dragging of downloaded maps without black borders. Is it the pygame that makes the difference or the way tiles are stored/accessed ?

Re: Maemo Mapper v2.0
 

would be nice to have in the repository settings the zoom levels supported too.

Re: Maemo Mapper v2.0
 

Pymapper doesn't have to deal with screen rotation. Pymapper probably does the same thing that Maemo Mapper v1.x did, which is load a 4x3 grid of maps into a 1024x768 buffer (or larger?) and pan the view around it. You can't take advantage of the same initial assumption when you're rotating the viewpoint, because now you have to load maps into non-parallel pixel spaces. For example, to load the same 5x4 grid of maps into a buffer to draw (and pan around) on the screen, you'd need 1280x1280 pixels (> 6.5 MB of buffer). And to have the same pannability as the non-rotated situation, you'd need more than 4x3 grid panels, increasing the number of panels that have to be accessed from the (relatively slow) database.

I'm not saying it's not possible to do it more efficiently. It just wouldn't be easy to do now, given the current codebase. I can look into reducing some of the blackness without increasing the memory requirements (by too much), but right now my focus is on stability and features.

Re: Maemo Mapper v2.0
 

I assume that if I am not connected, it doesn't matter if the maps are downloaded, the route cannot be reconfigured, correct?

Re: Maemo Mapper v2.0
 

@Gnuite

YOU ARE A LEGEND MATE. Quite honestly how you find time to not only develop but then maintain, bug fix and hag around in here looking for and answering questions AND most likely hold down a paying job I have no idea. But I am more than thankful for your efforts - especially as NONE of the commercial offerings for navigation do New Zealand any justice at all.

I haven't had time to read every post in this thread (that's what happens when you go away for a couple of days) but here are my initial observations from v2.0 (I haven't even had time to get to the .03 release)!

Yesterday I knocked out 450km on a journey to Auckland and back - here that equates to about 7.5 hours driving on the roads we have! I used Maemo Mapper v2.0 the whole way and found...

- Very stable on my N800 and works just fine with my GPS unit.

- Have you changed the positioning algorithms as I reckon it is about 5m or so more accurate that 1.x?

- Right now it does seem to suck juice quicker than previous versions. Yesterday was about 8 hours up time for the N800 with BT on. The journey drained the battery completely a couple of times. Previous trips I reckon only used 50-70% as much juice. I have no data from it (quite frankly I was paying too much attention to the road ;o) but could this be the device sucking more juice when accessing the DB?

- Definitely v2.0 is using more processing as I can no longer easily run Kagu and Maemo Mapper with any degree of responsiveness from the UI at 100km/h.

- Also it appears that when running at Level 4 to 0 that after a couple of hours up time MM starts to struggle when updating the maps. I have a screenshot when I arrived home (just need to get it online). The timer icons in the top left seem to represent a new map load or position update and after a while these start to build a fair old queue. By the time I pulled into the garage there would have been a good 20+ queued which equated to approx 500m of delayed travelled information. Damn funny walking around house showing me at 50km/h.

Interestingly the UI correctly displayed the position updates, time etc in the GPS info panel.

Is this just a reading from DB issue or the memory stack not clearing down quickly enough to start throwing new stuff in?

- Google Street Maps for rural NZ pretty well are accurate but occasionally roads are missing (not a MM issue but pretty confusing none the less).

- The UI for creating routes is pretty well unusable in the car. Gnuite - don't take that as a criticism I just can see now why commercial GPS nav systems have more Canola'esque UI's. Big buttons rock at 100km/h. (BTW Kagu really sucks at this - you trying hitting the pause button at speed).

Again a top effort and one for which I, and I am sure many others, are truly grateful. Someone near him buy him a pint.

Re: Maemo Mapper v2.0
 

I have actually seen this problem too and I've been using Maemo Mapper for a while. Once I tried several times to drag up and down, but it wouldn't move until I first dragged left or right, then dragged up an down.

I tried several times because I couldn't believe it. But it doesn't always happen.

Re: Maemo Mapper v2.0
 

Correct. The routes are computed by the google maps server. If you're not connected to the net, well, you get the picture.

Re: Maemo Mapper v2.0
 

Gnuite,

I'm experiencing a problem that you fixed somewhere between 1.4.5 and 1.4.7:

I am getting lots of repeated updates of the route (as if I'm off track), even when I am still on track.

Anyone else experiencing this?

Re: Maemo Mapper v2.0
 

Gnuite,

How difficult would it be to set zoom level based on speed *and* make the zoom/speed threshold configurable?

I use Wayfinder and it does this, but it's not configurable. Having both would be great.

Re: Maemo Mapper v2.0
 

Thank you once again, 2.0 very stable and good travel for 1000km already is good so far. If I can buy you a beer anytime Mr Gnuite.
