[mapserver-users] WMS T time series data support

[Sushrut Shivaswamy]

Hey,

Thanks for all the responses. They were a great help.
A it turns out my dataset was in EPSG:32644 projection.

I ran gdaltindex again as:

    gdaltindex -t_srs "EPSG:4326" *-src_srs_name* "tile_srs" index.shp
*.tiff

to create an index with the projection of each tiff in the tile_srs column.
I then added the time stamp in each row and added the layer to the map file
with the TILESRS option set to the attribute name "tile_srs".

The GetMap request for the following procedure gave the error "All points
failed to reproject".


To avoid this I reprojected all my layers to "EPSG:4326" and added to the
map file without the TILESRS option.
To test whether the layer is time enabled I sent a GetMap request with the
time parameter outside the "wms_timeextent"
and I got an error saying that the requested time is out of bounds.

The images produced by the GetMap request are all still blank.

Can anyone point out where I could have gone wrong in this process.

Regards,
Sushrut Shivaswamy
