I just learned that QGIS 2.18 has a Tile Server (XYZ) provider in the Browser Panel. I created a large tile map using gdal2tiles and I'm trying to load it. However, I'm not publishing the tiles through a web server instead, I though about reading the files strait from the disk. So, in the Tile Server url I used file:///I:/SUL/rapid_tms_utm21/{z}/{x}/{y}.png
. The tiles do not load and I see the following error in the log panel: Tile request max retry error. Failed 3 requests for tile 13 of tileRequest 2 (url: file:///I/SUL/rapid_tms_utm21/6/19/38.png)
.
So, the questions are:
- Does QGIS Tile Server provider works with local files?
- Can I use the
file:///
protocol? How?
I tried the following lines as the TMS Server address:
- file:///I:/SUL/rapid_tms_utm21/{z}/{x}/{y}.png
- file:///I/SUL/rapid_tms_utm21/{z}/{x}/{y}.png
- I:/SUL/rapid_tms_utm21/{z}/{x}/{y}.png
- I/SUL/rapid_tms_utm21/{z}/{x}/{y}.png
- /I/SUL/rapid_tms_utm21/{z}/{x}/{y}.png
- /I:/SUL/rapid_tms_utm21/{z}/{x}/{y}.png
- file://I:/SUL/rapid_tms_utm21/{z}/{x}/{y}.png
- file://I/SUL/rapid_tms_utm21/{z}/{x}/{y}.png
And the tiles work using the TileLayerPlugin

For use of a local Apache Server from the ms4w package, I installed MS4w into
C:\ms4w\
and stored the tiles folder structure beneathC:\Tiles\
.Then I edited the file
C:\ms4w\Apache\conf
around line 252 to change the DocumentRoot to:Tiles can then be accessed by something like
http://localhost/{z}/{x}/{y}.png
This is rather a dirty hack, but works for me.
