[mapserver-users] Advice for a new server for a huge data set.

[Bob Basques]

Demitri,

You will want to build yourself a tile system (there are a number of tools for this) with an attached index of the tiles.  You'll need to build a set of tiles for each level of zoom (pixel scales) that you will be using in the map interface drill down.

With the right indexing of tiles, and proper tile building, you can serve up just about an unlimited size raster dataset.

MapServer includes some utilities to build a tile set as does GDAL/OGR.   Do a search on the keywords Mapserver, tiles and index, and that should get you close to what you are looking for.

Hello,

I have recently discovered MapServer and I wanted to get some advice about setting up a new WMS. I have a data set that is several terabytes in size that I'd like to serve.

As just a trial, I want to start with a single raster layer. Is there an example of a MapServer setup that I can look at that only serves raster images in the form of individual tiles? The raster examples I have seen use a single image that MS apparently slices up on demand, but no such single image for my data exists (it's far too big).

What is the recommended approach? I could write a script that can generate the images on demand from the raw data - can these be passed to mapserv? I can also pre-generate tiles of the whole data set. If I want to implement a zoom, presumably I'd generate multiple sets of these at different scales? Would each zoom level be a new layer?

I'm sure I'll have lots more questions, but this should start me on the right path!

Cheers,
Demitri
