Great Application, Simplifies a lot of things. I have some concerns though.

1) I was not able to download #world though... any ideas?


----------------world.map----------------
GoogleMap
0-6 : -90,-180 : 90,180
----------------/world.map----------------


2) Also, I just have a humble suggestion, is there any way in which we can change this... from below


(is case with the current method)
----------------cache.conf----------------
version=3
tiles_per_file=1
----------------/cache.conf----------------

In this case the maximum size was less than a few KB's ... it created Hundreds of folders (500+) and almost 20K files....

to



(used to be the case for old Method)
----------------cache.conf----------------
version=3
tiles_per_file=32
----------------/cache.conf----------------


In above case, the maximum size of 1 mgm file I encountered was less than 1 MB and total number of files is considerably less than 1K (number of folders were only limited to number of zoom levels)

The reason I am requesting this is because currently with titles per file as 1 makes small file sizes and number of files is very high. (which ultimately occupies and allocates more space)... what i mean is see below....
-------------------------------------------
Size: 8.44 MB (8,858,41B bytes)
Size on disk: 73.8 MB (77,279,232 bytes)
Contains: 18,527 Files, 525 Folders
-------------------------------------------

Earlier with every thing same the sizes were as below
-------------------------------------------
Size: around 9 MB
Size on disk: around 9.5 MB
Contains: 512 Files, 8 Folders
-------------------------------------------

That is correct, it gets all the map tiles that cover the area selected. At zoom 1 that's all the 4 map tiles (the entire world), while at zoom 2 it's still 4 map tiles covering a smaller area around (0,0).

Shouldn't it be 90,-180 : 90,180 for all zoom levels....

any ways here is the new world map that works for me safely from levels 00 to 10 Very Happy without any errors or banning Very Happy ... i did get this figures by trial and error....

----------------NewWorld.map----------------
GoogleMap
00-10: -85.0, -179.99999 : 85.0, 179.99999

Some explanations about the world map restriction here : http://forum.mgmaps.com/viewtopic.php?p=5734#5734

"Smart" :
regarding "proxy list exhausted", you can force gMapMaker to keep downloading a new proxy list when current list is empty by modifying option "HaltOnProxyListExhausted" in gMapMaker.exe.config. gMapMaker works this way to avoid endless loop when none of the current proxies work.

Sometimes image corruption errors happen when something goes wrong in the http download. Corrupted image is deleted from mgmaps cache folder so that you just have to start again the whole download process, image previously corrupted will be downloaded again.

PostPosted: Sat Oct 06, 2007 4:47 pm    Post subject: Quitting gMapMaker Reply with quote

Hi Folks,

I might be quiting using gMapMaker....
Advantages: Very Easy to use, Simple and good interface

DIS Advantages:
Only Google Maps Supported
Occupies way too much of space
Way too many folders and files
Biggest disadvantage is inability to use multiple tiles per file


(Although the Fat32 with 1024 Cluster size helps to some extent) I have a Suggestion, if it downloads that way (multi folder multi files single tile per file), let there be at least a facility / application to change number of tiles per file after they are downloaded.

Also, I do not like the way the folders are organized.

Currently in gMapMaker folder structure is
MGMapsCache
--GoogleMap_0
----0
--GoogleMap_11
----(22 folders ranging from 11-99) and after this there are individual files each of less than 1 KB!!!...
This is just so harsh on my poor 6300 and the E: drive....

Old Method was Very simple and efficient.
MGMapsCache
--GoogleMap_0 ... and inside this only .mgm files same used to be the case with all zoom levels

I used to have 32 tiles per mgm file the max files used to be not more than 1 MB at most.... it was so convenient and so organized....

unfortunately, it was a pain to download in the cmd prompt window.... but then once downloaded, it was peace of mind...

Hi,

I'm sure gMapMaker will include (sooner or later) support for multiple tiles per file, even if most phones are very slow when reading large files with java (I'll try some workarounds for that). Even so, I think many people will still like gMapMaker in the current form...

Of Course I too like gMapMaker Cool .... it takes a while to getting used to so many thousands of files....

Cristian please please ... look for some thing even a perl script will do.... as i already have the required installations to run the .pl files...

I wish i had the skills to do some programming....

Dear Cristian,

i was replying to "(I'll try some workarounds for that)" for multiple tile per file issue / workaround to convert for already downloaded mgm file for 1 tile per file.

OK... multiple tiles per file is already supported but there are two problems: it only works with the perl scripts (not with gmapmaker) and the application is too slow when displaying maps stored this way.

Concerning multiple tiles per file and support for Yahoo! Map, it will be included in next release (v0.6) because it implies some deep modifications.

Since a lot of people were waiting for the bugfix in v0.5 beta, v0.5 has been released as is a few hours ago.

I use mostly Maps application (00-18 zoom) as compared to the Sat images (00-06 zoom). On my Nokia 6300 with 1 tile per file and 32 tiles per file, it hardly makes any difference to maps, but to Sat, there is some lag, but it's ok for me, others might have concerns Smile

As of now, I have both caches, one with 1 tile per file and other 32 tiles per file. using MGMaps, I am happy with both.

There's a very nice map dowload tool for MapThis! (on the PSP) called gmdl (Global Map Download Tool ) --> http://www.in7ane.com/psp/

Any chance your app could become compatible with that tool ?
Or ask that dev to make his tool compatible with your app ?

Don't know how different the two formats are ...

Just my 2 cts

I know about gmdl, I find it pretty difficult to use compared with gMapMaker (haven't used for some while though). Maybe I'll discuss with the author to make his tool compatible with mgmaps, but that's not a priority since we already have a GUI tool.
