[mapserver-users] Layer with over 6000 shapefiles

[Brent Wood]

This is less a mapserver issue than a data management issue - and shapefiles are not a particularly good way to manage data.

I suggest you look at a spatially enabled database, with attribute & spatial indexes, such as Postgis, instead of shapefiles as a data source. These are pretty much designed for such use cases.


That said, if you cannot use a spatial database in this case, you can do things with mapserver to improve things - like have multiple layers (though 6000 seems a bit excessive) in a single group - so addressable as a single layer but each with its own shapefile spatial index file.

Subject: [mapserver-users] Layer with over 6000 shapefiles
 

Hi,
Is there a way to add a layer that points to 6000 some odd shapefiles?  I've created a set of contour files for the whole world, and when I had the info in a single shapefile it was about 260GBs.  Mapserver would serve it up, but performance was horrible.  I now have the set broken up into about 6000 separate shapefiles, but don't know how to address that in a single layer.  I tried using gdaltindex, to create a single index file that points to all the other shapefiles, but I get an error saying the shapefiles are an unsupported type.  Is there some other way to create an index that Mapserver can use to point to this many shapefiles?
Thanks,
James
