I have saved MVT tiles locally like this,

c:/3006/0(zoom level)/0(Tilecol)/0(Tilerow).mvt

Skärmavbild 2021-06-29 kl. 13.01.15Information about the tileset below.

<TileMatrixSetLink>

<TileMatrixSet>3006</TileMatrixSet>

</TileMatrixSetLink>

 

<TileMatrix>

<ows:Identifier>10</ows:Identifier>

<ScaleDenominator>14285.71428571428623399697</ScaleDenominator>

<TopLeftCorner>8500000.000000 -1200000.000000</TopLeftCorner>

<TileWidth>256</TileWidth>

<TileHeight>256</TileHeight>

<MatrixWidth>4096</MatrixWidth>

<MatrixHeight>4096</MatrixHeight>

 

When I RUN the Workspace I get this translation log (see link) and no GeoJSON file is to be seen. What do I do wrong?

As far as I can see the workspace did read 0 features and write 0 features.

It's quite hard debugging what it does with a log file only. Can you share your workspace?

From previous questions and answers I think you want to create an offline copy of a basemap, is this correct?

Did you understand what @virtualcitymatt​ tried to explain about the TileMatrix Set?

Hello,

Updated with Workspace, Zipped MVT files and GetCapabilites Info.

 

Yes I want to create a local basemap. As I have understood it, MVT files must follow this file structure to be placed correctly (https://docs.safe.com/fme/html/FME_Desktop_Documentation/FME_ReadersWriters/mvt/mvt.htm). I have tried to replicate but with no luck. Not sure what I'm doing wrong.

 

Thank you for taking your time!
