Hi FME's heroes,

 

 

I've got a question about the webmaptiler transformer.

 

I'm trying to generate tiles for a Google Maps API map but the numbering in output does not match to what I expect. I read the doc and tested the different attributes fanout, the different schemes, but I'm still stuck...

 

 

I expect that (generated with QGIS) :

 

 

 

But I get only 

 

 

 

 

Any idea how to do ?

 

 

Thank you from France for your help

Hi AymFR17

 

You should be able to reproduce this structure in FME with a combination of:

 

- the AttributeCreator which can be used to make attributes combining the various quadkey, zoom level, row and column attributes needed

 

- fanout feature type which will make files based on attribute values

 

- fanout dataset which will make directories based on attribute values

 

 

Looking at your screen shot I can't quite make out the scheme you are hoping to replicate. Can you tell me the zoom level and the approximate location in Sperical Mercator coordinates and I can likely give you more detail on how to acheive this.

 

Thanks

Thanks for your answer Ken.

 

 

Here are some more informations :

 

- Zoom level wanted : 19 only

 

- Approximate location is over Brussels in Belgium, in EPSG 3857 : X 150000, Y 170000

 

 

It looks like each folder name is the column and each PNG name is the row according to this site : http://www.maptiler.org/google-maps-coordinates-tile-bounds-projection/

 

 

Thanks
