Re: Questions about the MaemoMapper
 

I guess I don't really understand POI. If I am passing a location that I want to record the location, I do a "set mark". How do I turn that into a POI? I haven't had much success with sqlite and POI databases. I think I have properly built a POI table and Category table using a sql statement I found. Do I have to dig into the track file Isaved and find the mark I set so that I can use the information to manually insert a record? That seems like a lot of work.

While we're on the topic of POIs, could someone point me to a simple POI file and tell me how to get it into the database? I got the one that someone posted from Italy told mmapper where the file was (settings->poi) but I don't think I ever did anything to make it get entered into the sqlite table.

If this is covered somewhere in a howto, please point me to it.
thanks, rhackenb

Re: Questions about the MaemoMapper
 

The only non-manual way to convert a track mark into a POI is to first save the track to a file, then open the file as a route. You can then tap-and-hold on a "waypoint" of the route and select "Waypoint | Add POI..." from the pop-up menu.

The reason this works is that "marks" in a "track" are equivalent to "waypoints" in a "route." There is no way to make a POI from a track mark, but there _is_ a way to create a POI from a route waypoint, thus you need to "convert" your track mark to a route waypoint by saving your track to a file and then loading that same file as a route.

I good explanation of tracks vs. routes and marks vs. waypoints is in this post, if you're curious.

Re: Questions about the MaemoMapper
 

Thanks for the explanation about the correlation of tracks to routes. My problem is that I don't understand how the data is stored.

I seem to be able to save locations to POI for a specific mark on a track (as a track file). What puzzles me is where this info is saved. I used sqlite to see the data entry stored. When I use sqlite (not sqlite3) with /media/mmc1/poi/poi as the argument, I get the following:

/media/mmc1/poi $ sqlite poi
Unable to open database "poi": file is encrypted or is not a database

Yet, when I do a "grep Point000 poi" on that file, I get:
Point000003turn to marina
Point000002#*
Point000001

This seems to be consistent with locations that I entered from mmapper.

Why can't I read the database with sqlite? Do I need sqlite3? If so, I can't seem to download and install sqlite3 because the only repository where I can find reference to it is: http://eko.one.pl/maemo/eko.one.pl.install
That gets me a "[403] Forbidden : Dostęp zabroniony" error.

Do I need sqlite3 to read this database? If so, how do I install it and do I have to first create the poi and categories databases? Is there a top-level guide to mmapper, POIs, and sqlite?

Try this: http://eko.one.pl/maemo/dists/mistra....8-1_armel.deb

Yes, you need sqlite3, not sqlite (v2)

Re: Questions about the MaemoMapper
 

Almost there. I was able to download sqlite3 from the link you gave. However, when I tried to install it, it said that I also needed libsqlite3-0. I can't get it from your site for the same reason (403 error). Could you send the link for the library? Also, why are we getting a 403 error in the first place? Is the link wrong on http://eko.one.pl/index.php?page=Nokia770_software?

Thanks,

Proper link:
http://eko.one.pl/maemo/index.php?pa...one.pl.install

not ... /maemo/eko.one.pl.install. BTW: my sqlite3 packages is in mistral repo, not bora.

Re: Questions about the MaemoMapper
 

When I visit that link, the application manager opens and tells me that the package cannot be installed. What is missing, apparently, is libsqlite3-0 version 3.3.8. I currently have version 3.3.5-0.2osso1. Where do I find version 3.3.8?

Also, am I supposed to be in red pill mode when I do this?

Thanks,

Re: Voice and Waypoints
 

How do you activate Flite through the application manager? I have tried downloading updates and latest applications but I never get anything on Flite. Is there a direct link to download this particular software? Please advise. Thank you,

Re: Voice and Waypoints
 

flite is available from the same application repository as Maemo Mapper. All you have to do is install it and enable the voice synthesis option in Maemo Mapper's Settings dialog (in the "Announce" tab). Here is a link for downloading and installing flite:

Questions on accuracy
 

Great product and thanks again for supporting OpenStreetMap.

I am using MaemoMapper with an i-Blue BT-GPS to log tracks that I process with OSM. I use the OSM map repository to see what I have not yet tracked.

What I notice, is that the accuracy of the MM tracks is not always good. It is okay if you do long forward stretches, but tends to give a lot of bogus results when you take a lot of turns in cities (which I do a lot, because I want to track every street and every corner). Btw: I wait at every turn for the signal to stabilise.

What I am wondering is, is my GPS giving bogus results (due to buildings, sharp corners, etc.) or is MM doing some optimistic prediction when the signal is of less quality?

If so, would it be possible to switch prediction off and just track the points that are good (i.e. skip points where the signal is below a certain treshold?). This would make MM an even better tool for OSM track usage.

Best,
Zoran
