Re: MapTiler can't warp

[Jeff Boothe]

I loaded a modest 1280x1280 image and set the 4 bounds manually and error dialog "can't warp" resulted. 

Any word on this? 

Thanks,

Jeff

Jeff,

Please provide more details (step by step what you did), otherwise nobody can help you.

No word until we are able to reproduce the error on our side.

IMHO you probably typed numbers in wrong order or specified wrong coordinate system.

Regards

Petr

Petr,

Thanks for the reply. 

Here are the steps I took. 

Using this site http://www.maptiler.org/photoshop-google-maps-overlay-tiles/ , I generated that attached image and used these coords:

-9131317.586575875 3247051.0726798973 -9131126.494005162 3247242.16525061

In MapTiler:

 - chose Mercator Tiles

 - loaded the attached file

 - chose WGS84 EPSG:4326

 - chose bounding box option

 - pasted in the coords above

 - choose an export location

 - errors “can’t warp” here

Jeff,

In MapTiler:

 - chose Mercator Tiles

 - loaded the attached file

 - chose WGS84 EPSG:4326

Here is the problem. You were suppose to select "Web mercator EPSG:3857"

 

 - chose bounding box option

 - pasted in the coords above

 - choose an export location

 - errors “can’t warp” here

Regards,

Thank you, Petr - that did it!

Can you recommend some good resources to learn more about the different coordinate systems?
