Windows maps download tool for MapThis! by in7ane

[deniska]

I have a 1 gig stick, so size for the most part is not a prob.
But when I follow your directions it still does not give me a big map coverage and small zoom.
I do not need to zoom in too much just by two levels or so. It does not take the entire area, only a small part of that map and zooms in.
The pic I posted is what I zoomed it to, and only need to zoom 2 levels lower.
It just is not doing the entire map. Really strange.
If i take the map I have and rip it, it will not give me the entire map.
Only the middle of the posted pic...
I'm tryin to not confuse you... Hope this helps...

Basically, when I click the preview 1X it does not match the overall map and it does not give me the whole map.
Do I have to zoom out farther?
My thinking was that Whatever it shows on the screen it will make a map out of, Like the encircled area.
Thats what I need. From the bottom to the top left.
Still confused?
I am...
Thanks for your help anyways...

I still don't understand exactly what the problem is..
Perhaps in7ane can look in to it and post some comments...

Keep in mind that the tool tries to round up your selection to the nearest tile at most distant zoom - so yes - the preview (and the resulting map may shift a bit)
If you need just 2-3 zoom levels - then the different between max and min zoom settings must be 2 or 3 respectively..

Here is yet another beta build in which I fixed a couple of GPSFS bugs and added
"distance to marker" for regular (GPS off) map mode.
Since I am preloading tile indexes in to the memory, there may be significant (10-15 sec) initial load delay for large (1024x+) maps. I put in a little "PLEASE WAIT...." message... After the initial load the map seems to have pretty fast load times...

Anyway, give it a try and let me know if you find any bugs...

deniska, everything works as far as I can see, thanks!

One request though, could you include scale images for -1, and -2 zoom levels (for satellite imagery).

Let me know when you want to make this final so I can get a newer version GMDL out at the same time.

I have ben testede the new version (mapThis_v3[1].7_1.5_EBOOT.rar) and everything works OK.

Error : (I use Dark_Alex's Custom Firmware 2.71 SE-B')
I have a map (1024x+). When I zoom to the low Map-level (tested in map-level: 1x, 2x and 4x) and move cursor for long time (one minute), MapThis is suddenly showing the attached Image (I have maps in this arear). I have done this severel times in defect maps places. If I then try to use MapThis, example to zoom out, the application will stop working. I do not get this error in map-level 8x.

This happaned because of inefficient garbage collection algorithm I used to clean up unused tiles from the memory... It was too slow on large maps (especially noticable at close zooms) - and system ran out of memory...
I re-wrote it with more efficient one (hopefully got it right) please re-test with new eboot...
Also, added the scale support for negative zoom settings (applicable for satellite maps) - just copy the attached scale.png image to system directory...

Russoxley187, if you are downloading from Google Satellite or Google Hybrid (which downloads from satellite) - they ban your IP for a few hours if you get too many tiles from them.

So how can I load a large map from Google Hybrid? I was banned 2 or 3 times already =)

try yahoo....

[gl0om]

maps of yahoo, msn etc. are of awful quality and hasnt 2x zoom level pictures. Well.. ill try to load my map manually =)

I took another look at Chinese maps (maps.51ditu.com), the setup is as follows:

To go north a row add 1048576 (at any zoom it seems)

To zoom in subtract 1099511627771 to get the bottom left corner

To go east add 1

What remains is the secondary parts of the url (1 at zoom 11 to 8, 2 at 7 to 4, 3 at 3 to 0) which I imagine may be to do with the maximum number of files per directory that they store. If somebody has any ideas, it would be much appreciated.

gl0om, a dynamic ip would help - beyond that... it's just under 1000 tiles at a time :/

Perhaps, in7ane, as "official creator and maintainer" of the download tool can add "map download corrector" feature where the application would check all the tiles in the existing map and download whatever is missing..
