I was using GoogleMV to create map slices for GPS Tuner but now I've found the best method is to use GoogleMV to just capture one large high res map and then use the free GPS Tuner Map calibrator to create suitable map slices for Tuner. Heres's my work flow so far:

Step 1 Use GoogleMV to go over the interested area capturing the files into the cache at high zoom.
(if banned re-logon with ISP to generate new IP address)
Step 2 Again with GoolgleMV zoom out and then save a single high zoom map of your selected area. A .map calibration file is also created automatically. (Most files for the map should now already be in the cache and so no hassle with Google banning your IP at this stage)
Step 2 Check the map in image viewer (Paint Shop Pro in my case)
Step 3 Convert the calibration file from .map to .gmi using the above mentioned converter.
Step 3 Edit with notepad the first line of the calibration file to change 'GTM' to 'Map' text.
Step 4 Bring the map into GPS Tuner map calibrator application and save the map as Multiscale map slices. This uses the .gmi file for calibration but on save also adds some extra bits of information into the file. I found that the auto map select feature of GPS Tuner only works with .gmi files that have been saved using GPS Tuner map calibrator application.

For GoogleMV zoom level of 18 seems to be limit for my area. 17 is limit if I need hybrid maps.

The end result is calibrated maps at the highest resolution that are quick to auto load in GPS Tuner, without white space, and I can zoom out to the lower zoom levels with auto loading of these maps as well.

Overall its not so hard or complicated to do and there is no need to split up the maps with GoogleMV. Aprt from captrung maps in the GoogleMV cache is fairly quick too. I am new to this stuff and it took me many hours of surfing and experimenting to figure it out. I post here so that others can get off to a good start with GPS Tuner. As a nooby I expect there could be better a process? Feel free to add suggestions.

It seems the default or recommended settings are not working for hybrid maps. Anybody have new working map source settings?

map

It seems that map and hybrid have swapped places. The default doesn't work anymore. I did find that if I uncompress the GoogleMv zip and start a new instance then the url's are correct from the start. If I then press default button they get swapped. It seems that GoogleMV on first start gets the correct ones.

I have been following this thread for a few weeks now.
I have downloaded the software and changed it to English ver.
I have followed all the problems of subscribers and the solutions and where appropriate I have tried them.
I have, with reluctance, switched off my pop-up blocker
Still all I get is the grey screen with loading written over it.

Is there anyone out there with the patience and time to blog full Instructions for Dummies for this software?

It looks useful and it is frustrating not to be able to get a handle on it.

Thanks

Thanks for that ETXEGARRAIA.

Still no success. I am away for a week or so, when I come back I think I will download the program to my wife's computer and try everything again.

If that does not work I will be back for more help!!

Cheers, Ian

Hi, I have the same problem. Tried to zoom out to the max, but no picture seen... Tried the help from cpasoft (show map in browser (opera), the show the picture address and paste to GMV), but nothing changed. What's wrong?

Replying to myself: the previous version 2.9.0.50 didn't work, I tried download older version from first page of this discussion, but it is newer version and it's working fine (2.9.2.0).

One day after... :-)

There is problem with hybrid map. I tried to download hybrid map of larger area (ie. one county), it creates about 3000 .map files, but when downloading and creating .jpg files GMV hangs. It seems to be working, but when looking to firewall, it pings few data to server, but without answer, it realy doesn't donwload anything. In folder where .map files are stored it creates one .jpg file, this file is okay, the second and maybe the rest are complete grey with announcement: Loading image.

When this happen, I can't look to hybrid and sattelite image in my browser (IE and Opera). I'm trying to erase browser cache, to restart, to turn off firewall, but sometimes it helps, sometimes not. It seems to be Google blocking data mining from my IP for a while. But normal map works.

Has somebody experienced the same problem?

Is there a way to go from a map with the Google 'qrst' format to get its latitude and longitude?

Is it as simple as assuming the longitude is determined by e.g 'r' is 0 degrees, 'rq' is 90 degrees.

Similarly 'r' is latitude 0 degrees, 'rq' is latitude 45 degrees.

Hi, I have found one interesting mistake: GMV downloads portions of map in .png file, with 8 bit colour space. When you order GMV to mape your decided map and compile it into .png, colour space of the final .png file is 32b! After that, there is a very big problem to reduce colour spacel and convert this file. And, img2ozf file doesn't work with this file (now I'm not sure if with common .png can, but common .png is not problem to convert ie. to .gif).

If you make maps into .jpg with 24b colour space (16M colours), the final .ozfx3 is not so clean as if you convert 256 colour .png.

For example try to make some map from ocean area: source .png from google has 2 colours (blue only) and is all blue. Final file has 32b colours and on your monitor you see a grid (try to zoom at least 400%).

The second bad thing is a file size. I have marked whole Europe and downloaded it. Source .png in cache (800k files!!!) has about 2GB. Final .jpg has 30GB!!!
When I convert .jpg into .ozfx3, it is 3 times smaller than .jpg, but the size is still so big to use it on SD card.

Can someone help with this problem?
