[mapserver-users] TileIndex and relative paths

[Lars I. Nielsen]

Hi Steve,

You mean a symbolic link in the file system ? Well, that's not really applicable in my case.

I'm trying to keep the files for multiple datasets and tilesets in a logical structure, i.e.:

ROOT_DIR/
..	Dataset1/
..	..	(dataset mapping file)
..	..	Tileset1/
..	..	..	(tiles and tile index)
..	..	Tileset2/
..	..	..	(tiles and tile index)
 ..	..	Tileset3/
..	..	..	(tiles and tile index)
..	Dataset2/
..	..	(dataset mapping file)
..	..	Tileset1/
..	..	..	(tiles and tile index)
..	..	Tileset2/
..	..	..	(tiles and tile index)
 ..	..	Tileset3/
..	..	..	(tiles and their tile index)

The mapping files are specific to a single "Dataset", and each tileset is set up as a layer in this.

I would like to set my SHAPEPATH to the Dataset folder, and reference each tile index using a relative path. This works.

The problem arises because I want the tileindex to reference the tiles without a path, so their movable in the file system.

But if the tiles in each tileindex uses the mapping file SHAPEPATH only, I cannot maintain a simple structure.

As it is now, I have to add the tileset folder name into a relative path for each tiles (e.g. Tileset2/Tile45), thereby hardcoding them to a specific tileset folder (name).


I think it would be beneficial if one could specifiy, that the tiles paths were to be considered relative to the tileindex file.


Ps! I'm on a Windows box.

I'm afraid your stuck. Can you do a symlink?

Hi,

I'm using Mapserver to display a raster, that I've split into multiple tiles for performance reasons.

The shape file I'm using for tile index have no path in the Location field, just the file name of the raster tile. And each tile (png) is accompanied by a wld file.

I've previously used absolute paths in my tile indexes, but this is not feasable in this project.

It looks like entries in a tile index is attempted read from the folder defined by the environment variable SHAPEPATH.

I would have thought that entries without path were to be considered relative to the tile index table itself.

Is there a way to force Mapserver to fetch the tiles relative to the tile index instead of relative to SHAPEPATH ?

Cheers.
