[Gvsig_english] How to see my map tiles in GvSig Mini fromMaptiler?

[Juan Lucas Dominguez Rubio]

Hello,
I know some WMS servers which deliver the same image for EPSG:26915 and EPSG:32615, which means they are considering the NAD83 and WGS84 datums to be equivalent.
 
I think gvSIG Mini does not know what the code EPSG:26915 means, but probably knows what EPSG:32615 means, so take those tiles in EPSG:26915 and use the code EPSG:32615 in the layers.txt file (pretending that they are in the hopefully equivalent EPSG:32615)
 
If that lets you browse the tiles but you notice an offset in the map, then maybe you'll have to reproject the original image before creating the tiles.
 
Regards,
Juan Lucas Domínguez Rubio

Hi,

This is the result of my MapTiler process.

I copied the tiles into this directory /sdcard/gvSIG/maps/MillerL

I am attempting to complete the folllowing layer information.
[1]
https://confluence.prodevelop.es/display/GVMN/How+to+add+a+new+layer+to+gvSIG+Mini

based on the information below.

I am confused.  I created the tiles from the following coordinate system
NAD 1983 UTM Zone 15N   EPSG:26915

As you can see in the results below it does not show that EPSG code but it
does show 5 other EPSG codes therefore I am not sure what EPSG code to use
for the layer.txt file.

Please advise on how you would use the information below to create the creat
text to insert into the layers text files so I can use my tiles in offline
mode.
