Hi,

I was wondering the same thing. I currently want to get a detailed map of an area from Flint Michigan to Myrtle Beach but it takes up like 12 gigs of space. Is there anyway around this?

Thanks
Wup

p.s. I am new, but i have been doing some reading---also nice work on maemo mapper Gnuite

Wow, 12 gig means I can forget about keeping whole US and Canada. Now I am fearing that I may not keep at least Kitchener and Toronto detail maps with my 2Gig Card.

I've got a good portion of New England download, it really depends on the zoom level you are looking for. Normally I download the upper level maps for the bulk of my drive and download the more detail maps when I get closer to my destination and that saves a ton space right there. If you know your destinations ahead of time this is more then acceptable. If you're a traveling sales person maybe not so much since you don't always know you destinations ahead of time, but finding hotspots now a days is fairly easy. The other thing you can do is get a decent cell phone with bluetooth and a data plan so that you can down load maps and routes on the fly which solves the latter.

My plan is to keep street level maps between waterloo and toronto in Canada. I mean to say whole city map of waterloo/kitchener/cambridge and Toronto GTA. I need a zoom level of showing at least street name.

If you guys have ever used Google Maps, you know how zoom levels work: as you zoom closer in, you can see the names of more and more streets. Even at zoom level 6, you can see street numbers for most of the larger roads. The key to minimizing disk space utilization is picking your level of detail at certain points on the earth. You can download all of North America at zoom level 8 in very little space; at that level, you can see state and inter-state highways. Then you can download areas around you (your state, or surrounding cities) at lower zoom levels, for your day-to-day mapping requirements. If you're planning a road trip across the country, you can download maps along your route in high detail (low zoom number) without using much space; the tradeoff is that you have to stick to your route if you want the detail.

Also, you can cut your disk space requirements in half by only downloading every other zoom level (either all evens or all odds). Very rarely is it useful to download every zoom level. I have a 1GB RS-MMC card, and with it I am able to fit:

1. The entire world at zoom levels 16, 14, 12.
2. The entire U.S. at zoom level 10.
3. The East Coast from North Carolina to Massachussets at zoom level 8.
4. Virginia to New York City at zoom level 6.
5. Major cities surrounding my home at zoom level 4.
6. My major city at zoom level 2.
7. Surrounding suburbs at zoom level 0.

(My card was formatted with ext3 with 512-byte blocks. I'll be able to fit even more with the database repositories available in Maemo Mapper v2.0.)

If you want to experiment with disk space requirements, consider using Winmapper to download maps in bulk and see how much disk space is required. Or, if you have access to Linux or VMWare, you can run Maemo Mapper inside the Maemo SDK and test space requirements that way.

That's a wonderful reply gnuit. Thank you. My 770 is on the way, I may receive it tomorrow. The first thing I am going to try on my 770 is this mapper software.

Now I am happy. I am hoping mapper v2.0 will release very soon (Do we have any estimated date when it is going to release? just curious .....!!!).

Which repository are you guys using? I cannot get a decent detail level on openstreets (nothing), googlemaps/ve streets (only basic view of south west england)

The majority of us I would guess are using the google maps repository. At the higher zoom levels the detail should be very good.

hi gnuite
I've a known problem with Maemo/Mapper : when the GPS receiver stops or gets out of bluetooth range, Mapper crashs.
The problem is that I use Mapper for creating tracks (for OpenStreetMap) and when it crashs it takes the track with him (in /dev/null ? ^^). Last time I lost a 3-hour track
When I reload Mapper it reloads a very old track.

=> could you add an option (in v1.4 or/and v2) to auto-save the tracks (every x mn) ?

Thanks for this great app !

Lately my Maemo Mapper (latest version) on N800 (latest firmware) does not seem to detect if there is no Bluetooth GPS device in range. It just sticks on saying "Searching for GPS receiver", while there is none (or any other Bluetooth device) in range. Before it used to work that after few seconds it said something like "No GPS device could be found... Retry?". If I selected "No" then the Mapper quit trying, just like it should.

I was wondering if the latest software installs (RTComm, UKTUBE, MicroB) coudl have caused this... but I tried uninstalling RTComm with no chance in behavior. I didn't try to uninstall the other software yet, since I could not think why they would have anything to do with this... or can they?

Anyone seen the same, or know how to resolve this?
