Always offset while tiling from Google Maps!
-
Hi,
I have a great issue while making tiles!
From Google Maps (resolution currently 100m == 63px) I take a screenshot from a part of Chongju.
Then I put it into Paint.Net in a new picture. There I select the usefull part and copy it into a greater picture (to collect).
Then, back to the Geoogle Map with Chongju, I scroll e.g. 7 times to right by the right arrow key, and then same procedure: Screenshot, copy the usefull part into the sample picture.
That way I did all the time and it was always fine!
But now I have always an offset, a (relative) great offset! E.g. near the top it fits, at the bottom I have ~5, 6px offset! <grrrr>I have already installed an earlier version of Paint.Net with which I know that it worked!
But always the same, I get an offset!
I also installed FF, but still the same: Offset!As I did my City tiles I used 20m for Google Maps and collected the screenshots in one big picture and all fits!
BTW: That is the reason why these Chongju tiles are so blurry. It is made from one screenshot…
Of course, I´m wondering what this issue caused.
Regards
EarlybiteEDIT:
If I´m correct it was 3D in Google! It makes a “deepening”. At width, center ok, right up, left up…
But I also worked with that option earlier! I´m pretty sure!
Howsoever, I can tile again. Now I make some non blurried!Best regards

Hmm I believe u know the tile is 1024x1024 in pixels resolution. Also it is 1km x 1km.
Maybe this helps with the offset?
Also have some points that you can measure from Google Earth. That way you will have a good reference.
Don’t use terrain or 3d from Google Earth.
Also as you move Google Earth looses the exact vertical view and u have to re make it vertical.Sent from TapaTalk

Earlybite, I strongly recomend you to use a dedicated software to get tiles.
There are many, but my favorite one, and easy to use is SASPLANET. Latest release is 070716 if I remember correctly
There you can select between diferent sources, select an área, with the resolución you Desire, and récord It with diferent formats, with específic prjection and such things.
Really handy, and of course free.
Hope you’ll enjoy It.
