John,
For the most part, GeoMoose relies on what MapServer can serve up. With
the exception of Aerial Photo's, the tiling of data doesn't really help
all that much (IMO) with performance issues. The OGR/Tiling/indexing
can be used, but even it goes through MapServer. All of my Aerial photo
datasets run this route as well.
There are a couple of folks on the GeoMoose list that have brought up
the idea of using tiled services. And I imagine the support will be in
GeoMoose sommetime in the near future, you can get more info from the
GeoMoose list on that.
With the right indexing you can get pretty good performance, see here:

Thanks Bob. Yes, GeoMoose does seem impressive for what it can do out
of the box. I noticed there is a GeoMoose mailing list and will
likely signup for that. Quick question though: can the GeoMoose
interface directly display png tiles (e.g., output from
gdal2tiles/maptiler) or do rasters need to go through mapserver
first? (I have some imagery and openstreetmap data I think would be
best served through TMS tiles rather than mapserver raster data sources.)

John,
First off, I'm close to the GeoMoose project, now having said
that. . .
GeoMoose will implement way faster out of the box.
Usually, the biggest hurdle, is if you need to change the
projection of the data you are displaying. If all your data is in
the same projection, it's not a problem at all, pretty much can be
a plug and play with the datasets using the samples that come with
the GeoMoose package. If you need to pull data from other
projections and overlay them onto your datasets then things get
decidedly trickier (in any application for that matter), although
once you have one layer working , it's usually not too big a deal
to get others working in GeoMoose too.
Don't take my word for it though. I'm sure others will pop on
here and reply too, although, you might want to try the Mapserver
list with the question as well, there might be some other viewers
out there as well that might fit the bill.

I'm looking for a web mapping package that can be used to show 15
- 20 datasets at once. These data just need to be turned on/off
and maybe an identify/query feature. Data are points, lines,
polygons, and rasters (aerial imagery, DEMs, etc...) Basically,
I'm looking for a way to show these datasets to a few dozen
colleagues located in various depts.
So far, MapGuide OS and GeoMoose seem to be the two best options.
I have used Mapserver and Postgis before and could use these
again. Vectors are mostly shapefiles and rasters are img or ESRI
grids (I could convert to png tiles using GDAL or something similar.)
Any thoughts on the ease of setup/config of GeoMoose vs MapGuide
OS? Any other obvious packages I'm missing? (I know about ka-map
but don't think it's being developed, and may not add anything
over GeoMoose/MapGuide.) In the past, I've used ArcIMS and ArcGIS
Server for such a purpose. However, I'm looking for an open source
solution.
If all goes well, we may develop a more sophisticated application
in the future but for right now, viewing the data is most
important. Thanks for your help.
